Metasonix TM-7 Scrotum Smasher 2007 - Yellow

"Metasonix TM-7 Ultra Distortion Scrotum Smasher
This particular TM-7 was modified at the factory to have a TRS connector that provides a stereo signal on the output.
Includes box, manual and power supply.
The TM-7 is basically a mean, angry guitar preamp made of three vacuum tubes. Plus a feedback loop which makes the preamp unstable. The first tube is a 6AK5. It was used as an IF amplifier in military radios and suchlike. We use it as a preamp—a BAD preamp. Then the signal goes through ANOTHER 6AK5. Finally, we have a 6BN6 tube. It was used as an FM modulation detector in cheap FM radios. You’re not supposed to use it for audio. But it has a neat effect….when overdriven, it sounds like a push-pull guitar amp driven deep into saturation. The SMASH switch selects the output desired. Down, and you get the output of the second tube. Up gives the output of the third (6BN6) tube. If you want maximum saturation, flip it UP. The TM-7 outputs are divided down, so they are more compatible with solid-state devices than previous TX series pedals."

"I was in the middle of trying to resurrect us about fifteen years ago and never got around to finishing it. There's still quite a bit of parts intact and populating the sport so the chances of repair are good."
