I do not currently accept any repair jobs, i could however possibly help (for free) via e-mail. I'm also always interested in buying broken gear for my own fun.
I had a small repair-shop run out of The True Vine record store in Hampden / Baltimore / Maryland / USA, it's not there anymore but the True Vine is possibly one of the best record stores / day care center for adults you've ever been to so it's worth coming by anyway!
I have also fixed a large number of amps, pedals and consumer audio stuff - but they're not as much fun to brag about. Also i'm currently not very prone to take on those kinds of jobs, but there are many other people around that can deal with those things unlike with analog synths / drummachines which nobody seems to repair around these parts.
