Wampler Pinnacle Limited Repair 

A mate recently dropped this off for me to look at. It just wouldn’t work. 

When I cracked it open I soon spotted the problem. A resistor has blown up, leaving black residue everywhere, and crumbling apart when touched. 

I jumped online and tracked down the schematic to work out the value. It’s the first component the +9v hits, so my guess is that more than 9v was accedently used, causing it to blow. 

I put in a new 10r resistor, and it came back to life. 

Great sounding pedal.
