MTI "Tubes" Pedal
One of the more unusual pieces of junk I have kicking around the shop is an old (probably '70s vintage) tube overdrive pedal made by MTI, the Japanese company who owned the Ampeg name for a time. The basic premise of the pedal is cool enough: it uses a 12AX7 running at "medium high" plate voltage with a Fender tone stack driving a single-ended output section with a small 7-pin pentode, transformer-coupled to a resistive load, with a switchable reactive load (namely, a tiny speaker hidden inside the case). The pedal looks cool as well, with a slanted front and tube cage on top. Unfortunately, it sounds like garbage! Anyway, this is the only one I've seen and I'm wondering if others are familiar with this unit. I've often considered stripping it down and using the case to build a better-sounding tube pedal, but have thus far preserved it as-is for reasons of historical curiosity.

Hey Dave,  
I've had one of those for about 10 years now and I just use it as a head-phone practice amp. Sounds ok through my old BF twin . Got it at a garage sale with a Mutron Bi-Phase thing, which i never use ..I think i paid twenty bucks for the pair.
