Pylepro wah not working correctly with Peavey Bandit 112 amp

SOURCE: i have a set of

Horn and speaker combo cabinets have an electronic component called a "crossover". The horn and speaker both work off different electrical signal frequencies. If you can take off the back, or get inside by pulling the speaker, check for a small circuit board mounted inside the box or on the speaker or horn. Check for a broken wire or loose connection of the crimp connectors.

A common problem with speakers, often the cone, or paper part of the speaker will come un-glued or separated from the magnet "voice coil". This happens when played too loud, when it's commected to the wrong impedance, or if the signal was shorted and "overdriven" (usually sounds like an awful buzz that's really loud).

Always make sure your output impedance matches the impedance of the speaker. Most auto stereos are 4 Ohms. Older home stereos are typically 8 Ohms. Musical PA gear varies between 4, 8, and 16 Ohms. Peavey gear is typicall 4 Ohms, but some older models are different. The Ohm rating is the amount of the resistance in the circuit. If your speaker is 4 Ohms and you plug it into an 8 Ohm circuit, you can destroy the speaker and sometimes the crossover circuit board.

Good Luck.

SOURCE: MG100HDFX Amp - crunch setting seems too loud

There are 2 channels, Which means there are 2 sets of knobs ... One for clean and one for crunch. Start out with a low master volume and set up the crunch, Then the clen and switch between the 2 and make adjustments until they match volume wise ... Then turn the master up.

check for cold solder joints from the input jacks and the fader. If any look suspicious (dull or grainy) re-solder.

SOURCE: guitar amp channel switch repair

Replace the switch. You gave no make/model number for your amp but if it has a jack for foot pedal operation of clean/dist function then try that. (on most amps) it will switch in spite of a bad front panel switch.

SOURCE: Ibanez Weeping Demon WD7 Wah pedal is not working properly

Sounds like a problem with the optical sensor. Your best bet would be to try to get a replacement from Ibanez or take it to a repairman. They are a resistor just like a pot but work by having an LED on one side and an optical "eye" on the other reading the amount of light passed thru transparent film. Morley has replacements for their wahs....not sure if its the same resistance. An audio repairman should hook you up.
