rp exploere “I’ve had this for several years and have decided it was time to part ways. It’s in fair condition considering its age. Everything functions fine, though some keys do stick occasionally (fixed after running through all the keys before playing) and there can be some static with the switches (also fixed by manually adjusting all the knobs and sliders first), probably just needs to be cleaned well. The external body is fine, minimal scratches but the labels have become faded. Has all original parts, including knobs and sliders.

It’s a very fun old school synth with some very customizable sounds. Great for a nice retro monophonic sound!” Link

explorer ” Up for sale is an ARP Explorer I synthesizer model 2900 from the early 70’s.
I’ve owned it for about six years and used it occasionally when gigging out. It was given a good going over by Sound Source in Rochester, NY when I first got it, and could probably stand another going over now. All of the switches and sliders work, but there’s a bit of scratchiness that’s telling me that the sliders need cleaning again.

The particulars:
-Serial #2900-0482
-Monophonic
-It has some scratches on the control panels, some black marks on the upper keys, two sliders are missing their caps, and the bottom particle board has a crack (doesn’t affect playing.)
-I will include a USB drive with files of: the owner’s manual, service manual, several factory patch settings, and blank template for your own patches.

All in all, it’s a really cool synth if your looking for that 70’s sound. I’m trying to slim down my collection and I just don’t use this one nearly enough.

I’ve tried to show all of the dings and scratches in the photos. ” Link

explorer” Selling a vintage ARP Explorer 1 synthesizer. Great 70s synth sounds! Features 4 mixable waveforms and noise, a fantastic sounds 24db/octave Moog style filter (ARP 4034 module), and an ADSR and LFO with modulation routing. Lots of range for a somewhat preset synthesizer.

The unit is great cosmetic condition as seen in the photos. Powers up and seems to be working fine. Comes with a 100-130V power supply input and 2-pin plug.
There is a demo video of the unit. Do get in touch if you are interested and wish to view it.

Considering it’s age, a bit of clean up and tuning would bring the unit up to its most optimum state.” Link

explorere” Up for sale is my ARP Explorer 1 synthesizer. This thing is a fun little one oscillator synth that is capable of some cool sounds. The electronics on this synth are all working well. The physical condition is not great however as much of the writing has been rubbed off at this point and some of the slider caps are gone. The key action is also not in great shape and would have to be re-done. However, it is still a lot of fun to play. Item is sold as-is, no returns” Link

arpexplorer ” For sale is a great shape and fully working ARP Explorer I synthesizer, mfg in the mid-1970’s . The factory model number is 2900. The key-less version of this synth was called the little brother.
The explorer is a combination of subtractive synthesis in the filter and ADSR , but with the capability for additive synthesis in the waveform and pitch sections/any or all waves and pitches at once.
Keybed can use new bushings to make the key action smooth as new. The rightmost high ‘C’ note has a tiny chip on the left side of the key, shown in closeups, otherwise, Cosmetically, it’s excellent/mint. It works great and all the major parts are original, no mods have been done. I have replaced a few capacitors and resistors that were aged. The power cable was repaired/ patched by the previous owner (inside the instrument). The only thing missing is the (piano-style) sheet music stand. I have thoroughly cleaned the sliders, j-wires and the inside chassis several times during ownership. The new owner will need to keep the instrument covered and clean to maintain proper working order. Any questions about the item please let me know! ” Link

explorer“Here is an exceedingly rare 1970’s ARP Explorer synthesiser. If you know synths then will know how rare these things are and that they don’t come up on Ebay very often.
Cosmetic condition of this is really good and has one small scratch on the top of the synth about an inch in length- does not detract from its beauty.

Synth works as it should and all keys play great with a nice action.
The volume dial is a bit scratchy and the resonance dial will need some switch cleaner etc. I would say it would benefit from a small service just to bring it 100%(I would say if you know how to clean the sliders yourself with switch cleaner then you will be able to do it yourself) but it is certainly very usable as is and is in tune and scales correctly.
All footage switches work and so do all the oscillator select switches.
The synth is from the seventies, rare and very sought after and it will only go up and up in value so grab this whilst you can. ” Link

“This is a genuine ARP Explorer I monophonic synthesiser from the 1970s. It’s in good working condition – some of the faders crackle a bit but all knobs/faders present and correct. The original cardboard bottom has been replaced by MDF by the previous owner, and I’ve taken a few pictures to give you an idea of the condition it’s in. It has a great white noise setting, which I’ll particularly miss, but hope it ends up going to a good home where it’ll get a bit more use than I could give it. UK-based bidders only I’m afraid, although I’m offer collection in person if the winning bidder is happy to come to London to pick up the synth. Happy bidding – whoever gets this will end up with a fairly rare bit of kit as I don’t think there are too many of these around these days.” Link

“This wonderful synth was lost in storage and found damaged when other boxes fell on it. It still works but has loose keys and the portomento and intonation is way off. Would make a great fix it project or a great noise maker. As is due to its condition. Some of the wood paneling on the side is broken and missing. I can kick myself in the butt for leaving it in storage, but my apartment is not much safer, so either way I would be kicking myself in the butt. I know how expensive these things are going for today, I wish I could list it for more, but It does need some TLC. AS IS.” Link

ARP, Explorer @ 26 June 2013, Comments Off on ARP Explorer Project Machine


I am selling this as is for parts. I plugged it in and got no sound. I know the pictures are some what grainy but the control panel is not rusty. The over all condition is good. All the keys move as they should. All sliders and switches seem to work. Sliders are a little sticky. It’s missing the tuner knob on the right hand side. It may or may not be fixable. There are places that repair these and there are owners manuals and a lot of details about these at arpexplorer.com” Link

ARP, Explorer @ 09 January 2013, Comments Off on ARP Explorer

“Case is scruffy in places but no major damage. Have owned it for over thirty years and used to gig with it in the early 1980s. It is monophonic and produces some very distinctive bottom end sounds. Took it out of storage recently and it wasn’t working – many of the switches and sliders had seized. I took it to a technician who has been looking after equipment for me for many years and he serviced it. As far as I can tell it is now working as it should and it certainly sounds how I remember it after thirty years. However, it has only been tested very briefly after thirty years of sleeping so whilst it does seem to be working as it should, I cannot offer any guarantee as to future performance although I have described it as accurately as I can” Link

“Zur Auktion kommt ein echter vintage Synthesizer, von denen es vermutlich nicht mehr allzu viele geben dürfte. Der ———————————————————————ARP EXPLORER 1—————– zählt zu den ersten Synthzesizern, die ca. 1972 auf den Markt kamen.
Die Auktion richtet sich natürlich an Liebhaber, denen klar ist, daß man in dieses Instrument zunächst ein wenig Arbeit und Zeit investieren muss, vermutlich auch das eine oder andere Bauteil ersetzen oder erneuern muss (bei den Oldies geht das!), bevor das Teil dann wieder so klingt wie im Neuzustand! Aber diese Investion lohnt sich für Liebhaber in diesem Fall sicher.
Denn alle sichtbaren Teile (Fader, Potis, Schalter etc.) sind offenbar in Ordnung und das Instrument wurde in den vergangenen mindestens 12 Jahren im klimatisierten Studio sicher aufbewahrt.” Link

“This is an Arp Explorer I synthesizer that still powers up, so I’m assuming that it still works. I have no way of testing whether the system creates sounds or not. It has been in a closet for years. All the knobs and sliders are there and work…the portamento slider is a bit stiff… and the last key, ‘c’ of the 37 is a little raised. The frame is sturdy and the cord is strong. Does not have the music stand or a manual. It’s small, portable, has monophonic presets and programmable sounds. Great vintage electronic synthesizer.” Auction ended. Click here to browse on eBay.

“Sadly, I am having to sell my well loved ARP Explorer as I do not have the space to accomodate it.

IMPORTANT – THIS ITEM IS NOT FULLY WORKING, AND WILL NEED A PROFESSIONAL SERVICE AND REPAIR BY SOMEONE WHO SPECIALISES IN SERVICING/REPAIRING VINTAGE ANALOGUE SYNTHS – also, please read the bottom bit before you intend to bid for this item.

If you buy this, this is what you will get:

ARP Explorer 1 not fully working – serial number 2911-0085 (likely part of the first batch made in 1974)

Original hard case

Original Users Manual – slightly damaged

Original Service Users Manual – essential for the repairs you will need to carry out. This is several pages long, designed to sit in a ring binder, and contains the circuit diagrams of the ARP Explorer. It does cover each part in some detail, and contians diagrams of each part throughout. I hope this helps.

9 Original Cardboard Overlay sound templates

1 euro (kettle) lead

The keyboard itself is fully working, with no dead keys – one or 2 are sticky, but I never found this a problem.

I am not technical at all but I will do my best to list the issues that need adressing:

Sawtooth and pulse width sound only works at 16′

‘Fuzz’ sound does not work.

Sine and Noise fully work across the pitch scale.

ADSR only works note on note off with immediate attack and decay – if the decay slider goes up a notch, the sound will infinately sustain.

All the sliders are a bit crackly, and there are a couplpe of dead spots on the volume slider.” Auction ended. Click here to browse on eBay.

“The most organic sounding,mono-synth I’ve ever played. Syncs accousticaly with guitar /drums/bass in a band setting moreso than most mono analogues of comparable build.Extremely fat Bass lines and ethereal stringlike repeat phrases are possible with this rare synth.What was meant to accompany the Arp Solina organ/string synth, at the time, is just that – a formidable companion; sound quality-wise and functionally.Of course it has the same styling ,as well.

This unit has faded text printing(old gold), and has been re-applied in some areas, and since faded – refer tp photos for a closer look.Since it is extremely easy to use, doesn’t take long to figure out what toggle or knob does what.I am including the patch sheets regardless, so it should be crystal clear,then.” Auction ended.

Missing Pitch knob, still works though,one of the 2 Output jacks is missing,jacks is de-installed.. and

a toggle for one of the presets is missing (but still switches)..seen in the pics.Sliders are a bit stiff,but not scratchy.

Missing slider caps too, but doesn’t matter.

This thing is a Bass Monster, served me well, and I am reluctant to sell,due to its rarity and usefulness.. Sounds great.

“Arp Explorer I 1970s synthesiser

I have had this since late 1970s when it worked fine.

I am selling it as spares & repair as it produces sound but the portamento appears to be jammed on. Also as you can see from the photo some of the sound switches are replaced. They’re not pretty but work. One other is stuck though.

The faders are very stiff. Cleaning these would probably resolve the sound problems.

Essentially with a bit of know-how and tender loving care hopefully it would be back working.” Auction ended. Click here to browse on eBay.

“You are looking at a very rare ARP synthesiser in nearly perfect condition.

This was made somewhere between 1974-78 so it’s at least 32 years old and for it’s age it is in remarkable condition really! There is one small chip on the wood of the left-hand side end cheek as you can see from the pictures. Other than that all knobs and sliders function with a small bit of crackle on the frequency. I think a bit of a clean with some switch cleaner should sort it out but I thought I’d better mention.

It sounds great, very organic and ‘real’ like analogue synths of this era do. It comes with all the music stand, original sound cards, also in great condition, the manual and service manual. This synth is perfect for a collector really.” Auction ended. Click here to browse on eBay.

“I have an Arp Explorer 1 Synthesizer. Also known as the ARP 2900.
I’ve owned it for about 5 years and it’s always been good to me.
The sound is real 70’s. Herbie Hancock used this on Headhunters.
From what i’ve heard, it has one oscillator from the Arp 2600, and the filter is the Moog lawsuit type.
Nice and fat, warm sound, and quite a diverse range for such a simple synth.
The oscillators can be stacked and waveshaped with the toggles to get a thicker bass.
It has filter/pitch lfo, portamento, adsr assignable to the filter and amp, cutoff/resonance.
The back panel has only two jacks, one for 1/4″ audio out, and one for a standard 3 prong ac cable.
It has all the things you would want in a basic synth. very usable. stays in tune.
Great lead synth, very musical sounding and always sits nicely in a mix.
I personally love how all the performance controls are under your left hand,
which makes it easy to tweak parameters while jamming along.

I’ve heard these are very rare. The serial number is like 135 or something, a low number.

Condition wise, the thing is definitely used, but not so abused.
All the slider caps are missing, but all the sliders work.
Some sliders seem a bit stiff and could use some lube i guess, but they work and don’t crackle.
There is one toggle (the saw wave) that has broken off, but it still can be switched with a pen or a key or something. it works.
One toggle (the noise osc) has been replaced with a generic switch, but it works.
All the keys work perfectly. Actually every function works.
The paint for the parameter function labels is quite worn and somebody in the past
has written them back on in gold pen, which has also faded.
The Arp Synthesizer logo on the back is still bright, as is the Arp Explorer 1 logo on the front.
The wood end caps were covered with a tolex sticker which i removed to reveal nice wood.

All in all, the thing is pretty badass. I was using it in an electro project and it looks great on stage and gives forth quite a loud dirty bass that rips through the speakers. It’s fun to play for sure.” Auction ended. Click here to browse on eBay.

“Hello, for auction is a great little vintage synth, 1974-75 ARP EXPLORER I, model#2900, first version/mark 1. Everything works fine and the only thing could be done to improve this instrument’s performance capabilities, is to re-bush three keys for smoother key action- Bb #1 and 2 and Eb#3

I’ve owned this about a year and a half, have since bought a minimoog and need to downsize. When I acquired this keyboard it was very dusty inside, so badly that some sliders’ functions were inhibited, so I thoroughly cleaned and inspected it, but other than that and since then I have not had to make any repairs and it now works great, it’s cosmetically beautiful on the outside, a few minor nicks and a bit of hazing on the top that should be clear in the pictures. but has some wear on the bottom panel, which is original but made of particle board, specifically the screw hole tabs, as pictured. The tuning knob’s metallic finish is a bit discolored/spotted but the knob is in great shape. The detachable sheet music stand is/was not included.” Auction ended. Click here to browse on eBay.
