“Metasonix TM-5, All pentode guitar preamp. Like new. Extremely rare!!
This is the most sought after of all of the Metasonix pentode hardware. And frankly, it’s the most useful and usable of them all. This device doesn’t just mangle audio, like the other Metasonix yellow boxes – it’s a very versatile preamp, can be used to add subtle analog presence to any audio! Not just for guitars!
Like new condition! I’ve only plugged it in a handful of times. It’s a beast, very fun to tweak, lots of cool features. It’s been a prized possession, but I’m entirely digital now, and don’t have use for analog effects like this anymore. Comes with power supply and original box.” Click here to visit listing on eBay
“Metasonix TM-1 Waveshaper And Ring Modulator Vacuum Tube/ Valve Distortion Pedal. Condition is “Used”. Dispatched with Royal Mail 1st Class.
“Very rare distortion unit which is great for real tube distortion and crazy tube effects. Unlike any other audio distortion I have heard. Comes with lots of extra NOS tubes for different tones. Reluctantly selling due to downsizing studio. Unit is serial number 127. Only used in a smoke free studio.
” This was purchased new and put away for over a decade. Recently found amongst a bunch of other pedals and random bits of gear wile moving. I own 3 of them along side other Metasonix gear. I had money back then and kinda went nuts on spending.
“BRAND: Metasonix
“Sad to see these go… By far the juiciest synth tones out there.

“This is a Metasonix 5-51 Vacuum-Tube VCA/Distortion for Eurorack format modular synth. This is a super fun, unique and quirky-looking module. These are not easy to find. Item has been used very little, fully functional and has little cosmetic wear. It will include the ribbon cable for power. It will include a second set of vacuum tubes to replace or experiment with (four fully working tubes total).”
