So I'll start with the fault;
The gain knob is super crackly when being turned, I'm guessing this could be quickly fixed if someone can get inside with some switch cleaner, but I'm not a tech so can't say for sure.
Otherwise this is a well used, but well loved workhorse. As you can see the top panel is somewhat scuffed from gig life but this is just aesthetic.
Anyone is welcome to come and hear the crackle for themselves before making a decision, or alternatively I could send a video on request to give a better idea.
This could be a steal (or even a money maker) for anyone who knows their way around the insides of these things!
