Testing Digitech Bass Modeler Pedal
« on: August 27, 2015, 03:21:19 am »
Hello, I came across a Digitech Bass guitar digital effects pedal but it's not turning on. It runs off 9 volts and I've been testing it with a multimeter. I don't have a scope, so multi meter is my only avalible tool. It uses 6 AA batteries, but for diagnosis sake I soldered a 9 volt battery connector to the battery pos and Neg pads to test outside of the case. Voltage is 8.67 on the battery, not new. It supposedly turns on when a guitar is connected. I placed the multi in series in amp mode and I get .02 with the input cable disconnected and jumps to 2.89 when I plug  in the cable. Does that seem to high to anyone? First attachment is the component side, second is the solder side. Third and fourth are the input jack, that is what turns on the circuit.

It cost me 3 dollars at a flea market and online it goes for 35 to 75 depending on condition. If I can get it going that would be great.
