I Need a bit of help with this, I am fixing up my old amplifier (Since my Fender one sucks), when i plug my guitar in it just makes a fussy sound (I got the Gain and Volume to work i dont know about the other three since i have to have my guitar plugged in to tell, I also replaced the Potentiometers), I had to scrape up some of the traces and use wires to connect the LM1875T to the next part Witch allowed me to change the Gain and volume.
