I basically got it free. The input where you plug in your bass is broken. Im pretty experienced at fixing things and soldering. My question is this- I opened it up n noticed that the "tuner" input is identical to the input switch. I don't plan on using the tuner function, can I just un-solder them and switch em around? I don't have money to take It to a shop, I'm pretty confident this will work. No diodes or electronics will be touched, only the plastic/metal input jacks. Any advice? Thanks!
