Some stitching has come undone on the purse but is still usable which don’t really matter because it has a hard plastic carry case with an eagle on it. Battery compartment is in good condition, just the sticker is a little discolored. Little to no wear around the buttons and knobs. 100% working condition, no operating issues.” Click here to visit listing on eBay

Roland, TB-303 @ 01 July 2018, Comments Off on Roland TB-303 with Devil Fish Mod

“Extremely rare Devil Fish modified Roland TB 303 baseline synthesizer version 2.1 A. In very good condition with some scratches here and there, but mostly on the underside. You can see on the pictures that this 303 has been used but not abused. In particular the markings around the cutoff knob and all other knobs are still there, a sign of relatively light use.

No scratchy pots. Everything checks OK. Power supply is not a Roland original but provides enough current for this bass and acid monster.

Among the many modifications, the Devil Fish provides extended bass response and extended controls. It is very rarely offered for sale on eBay or anywhere else and the last one that was sold here went for $5,500. Get mine for less.” Click here to visit listing on eBay

“Roland TB 303

Classic analogue synth.

All in perfect working order.

Serviced a few years ago in 2015 by Kent Spong of KSR.

The pots are nice and firm with no crackles.

Hasn’t seen too much use as you can see from the condition of the unit. That being said it does have a couple of minor surface scratches on the bottom and front side of the unit which I have shown in the pictures.

It was midi modded sometime back. This doesn’t seem to sync to midi but can be used to trigger notes. I always used it with a Kenton Pro solo to sync the internal sequencer.

Selling with power supply, din sync (sync24) cable and two mini jack to female midi connectors again as seen in pics. ” Click here to visit listing on eBay

“Chance to own the original classic TB 303 bass line. For that amazing acid sound. good condition for a 35 year old machine that has had plenty of use as most have. (see photos for condition). Fully working i have tested today as i havent used it in about 8 years. tested with batteries as i have no AC adapter. It did work with adapter when i had it in my studio years ago and still should. when tested I noticed a cracking sound when turning the volume but this faded to almost nothing after playing with it for half hour so should completely disappear with more use. it didnt do this when i used it regularly. ”

“This is an original gangster TB-303 thats lived in a non smoking studio environment for the past 5 years in Brooklyn New York. It’s produced for a bunch of records so its had a good life here and I would like to hand it off to someone that can take good care of it. I have a kid on the way and so I have to start becoming a dad. More picks off the TB-303 up soon.

I updated the picks finally. To answer a few questions you may have, heres a bit more info;

– No scratchy pots. All of the knobs work well with out any scratchy noise.
– There is no corrosion in the battery chamber.
– All of the in and out puts work.

– Batteries included. But you have to get your own DC 9v power source.”

“This Roland TB-303 synthesizer is the only one on the market with a Sync Output in the front bottom of the unit to be used as a daisy chain connection with your other equipment.

All buttons, knobs, plugs, and switches work perfectly. The maintenance has been done before to keep the unit in great condition (look at the last picture shown). It has never left the studio for preservation reason.”

Roland, TB-303 @ 08 October 2017, Comments Off on Roland TB-303 with CV Mod

“So sad to part with my beautiful modded TB-303 (but for now I’m going in a more digital direction)!

Has CV mod control over Pitch, Filter, Gate, Slide, and accent. Control this with a Maths module over the filter and kiss your brain goodbye! Use in tandem with a Kenton Pro MK2 and you have a midi slaved TB-303. I have used every single feature on this thing many a time and everything functions as it should. Ready to hook up to other Din Sync devices through the Sync In. Can also do an unofficial Sync Out, but I don’t recommend it.

Comes with original carrying case, and though it’s not pictured, it comes with US power supply.”

Roland, TB-303 @ 25 September 2017, Comments Off on Roland TB-303

“It pains me to have to let this go as it is the cleanest and most complete one of these I have seen. I have owned this 303 for a little over 15 years and it has had little use, especially after its service where all that needed replacing were the tact switches.

All working fully as it should do.

Comes with the correct Boss/Roland power pack, low interference and noise, which are in them selfs getting hard to come by, and Kenton din sync.

As I now have a young family it only gets sat high out the way with little love and use, I am almost scared to set the 303 out and use it with the kids about, through fear of them getting hold of it.”

It’s in perfect condition.
Since I’ve been an owner, it’s never been gigged.
Comes from a smoke-free home.

Includes:
– official, original Boss/Roland PSU (110v North America)
– original carry bag
– printed quick start guide

Earlier this year the button switches were replaced, so no worries about
double trigger notes or missed presses. This 303 works like new.
Also, it was tuned and calibrated at the same time.
I must say, this 303’s resonance is amazing. ”

Roland, TB-303 @ 11 June 2017, Comments Off on Roland TB-303 with DevilFish Mod

“This auction is for my Robin Whittle Devilfish modified TB-303. Robin did the original devilfish mods on this and then I sent it to him to do the Quicksilver 303 CPU mods. The patched holes you see on the front of the case are where the original extended memory upgrade from the original devilfish went. Robin did all the patching and was his typically meticulous self. All of the controls have been cleaned and upgraded by Robin during the process. The Devilfish was always in a smoke and pet free studio.

As you can see, this comes with the original Roland manual in excellent shape as well as the patch sheets and guide. The original case in excellent shape is also included and it all fits well in the road case. I have also included the manuals for the Devilfish and Quicksilver implementation. The little midi dongle allows you to hook midi up via the DIN port as that is how Robin implemented midi in this Devilfish.

These things are crazy sounding as I am sure you are all aware. One in this condition with these mods and accessories is impossible to find. I hope it finds a good home.” Click here to visit listing on eBay
