Can you repair a tear in a peavey guitar amp and will it affect the sound

Pedals operate at a different level then rack units that go in the effects loop.
It needs to go in front of the amp input. Guitar to pedal to amp input.

Do not mess with this yourself. Take it to a repair shop. The switch needs to be replaced, at a minimum and possibly other parts. There is lethal voltage involved in a tube amp.

Hi!
Unfortunatly, it's time to take it to the shop. Check the Peavey website for an authorized repair center in your area. An authorized repair shop will have better access to the parts and tech help from Peavey service.
No sense digging into the amp and getting a bad shock!
Good luck!

yes, if you know what is the amp module check.

Check speaker impedance or disconnect speaker leads, then use a 9V battery to verify cone movement and if this test is ok, then go inside the amp, if there's no fuses blown check opamps supply voltage which should be -15V at pin-4 and +15V at pin-8, let me know your results to help improvement.

Hi. My name is Danielle and I have a peavey rockmaster GT-5 guitar mini amp, and it can work with/without the cable. I lost the cable and I didn't need to worry because the amp still worked as long as it had good batteries. But, after about 4 months of no use of it, I put in a brand new battery and the light wouldn't turn on. I looked all over the amp to see if something was missing but I found nothing. I'm really not sure what to do because this is a very good amp and I'd hate to throw it away. Can anyone Help Me?

You will need at least a 24 channel mixer to give you spare channels. You also need an active crossover and a snake. The advice you need is too much to include here so I am including some links:http://mixonline.com/live/FixIts/, http://en.wikipedia.org/wiki/Live_sound_mixing, http://mixinglivesound.com/blog/tag/outdoor-concerts/,http://mixinglivesound.com/blog/, and http://www.scribd.com/doc/11435651/Beginners-Guide-to-Mixing-Sound. You may need more monitors than you are planning on and you might consider in ear monitoring.

About the cable,

This is from peavey.com:

. Plus, the Generation guitars that feature ACM come with a dual-ended cable that sends the two tones to two different amplifiers, opening up even more tone possibilities.
