I have an SD1 which I did the Monte Allums mod to (the basic one) which has worked fine for years but now has gone a bit weird.
Works fine when the od is switched out but when it is on the level and tone work but the gain is just fuzz all the way.
Any ideas would be welcome on what maybe to check first, all the mods I did still look okay but I guess the first thing I could do was put back the components I changed maybe.
If not what about a simple project to use the enclosure, jacks etc ?
