my crate 15 gts overdrive just went out, when i turn it on the dirty cannel the od knob just makes it get a little louder, i took it apart and everything is good. is it shot or can i fix it or should i take it in. its just a practice amp but i would like to have it working properly to sell it.
You could take it into a local gutiar shop and ask them what they think and how much they think it would cost to fix it, then you can see whether it will be worth it to get it fixed to sell...
