I know its a bit off topic, but I know there are some electronics guys who read this group.
I want to repair the small pre-amp in my bass guitar which has developed a fault. The circuit is based on a TL064 and TL062 op-amp and the fault is considerably reduced output voltage which leads me to suspect a resistor or capacitor going out of spec.
It is made by MEC and I've emailed them ( and the guitar maker ) asking for a schematic.
If I dont get any replies from them, any ideas on where else to try to get schematics from ?

PS. Its a 4 string thru-neck Warwick Thumb with 18 volt 3 band pre-amp, if that helps....... PPS. Yes I did check batteries, leads etc etc
