Model 6A Super Sustain Match Box - help with this, please

Ok, my son got this unit, the Model 6A Super Sustain Match Box, in trade, and sent it to me to try out, as I have a pedal steel guitar, and he doesn't. (Not that I didn't offer him one...)

Anyway, I hooked it up to my Blanton, and it doesn't seem to do anything. The signal comes out, but only if I turn the 6A up all the way, and when I do turn the pot up all the way, it makes a weird electrical click, like something is shorting out.

I already tried brand new batteries.

So, what am I missing? Does the Blanton already have so perfect a signal that this unit can't help it?

Anyone with a clue, please let me know what else to try.

Well Max,

This may sound obvious, but did you make sure the cables are plugged in correctly, and not backwards?

Good luck,
Benton

I had one and spent hours tracing down the circuit without a schematic, replacing bad transistors. I could not get a schematic or much support, unfortunately. Considering what one is worth I do not find them economical to repair, at current shop rates.

The first thing I would do is put in a fresh battery. A weak battery can cause all kinds of weird things to happen.

Maybe a bad/dirty pot?
