Where do I test for break in the Mx15r input cuircut if its not sending

SOURCE: Static Noise from guitar amp.

I take it you have made sure that both the cable to the distortion box from the guitar and the cable to the amp are both good. From the description you give, it sounds like there is no signal getting to the pedal. If the cable is good, then the next likely suspect would be the input jack on the fuzz box. Try wiggling it a little with the guitar cable in place to see if it is loose. Some input jacks are unbelievably cheap and flimsy. A crackling sound (static like) is almost always a bad connection. If it was the output jack, I would think that the guitar signal would come through a least a little bit, but you might want to try wiggling that one, too, if the input jack isn't the culprit.

Another possibility to check is the battery, but this doesn't seem as likely. Some effects units devour batteries, especially units that use 9V batteries. I have a multi effect pedal that kills a 9V in about an hour.

Check the input RCA plug going into the reverb tank (silver box with two wires connected to it). Make sure the amp is off when you do this. Sounds like the output is working fine if hitting the amp does it.

Bridge the preamp out to the power amp in with a short cable while suppling signal to the input..

IF that works, the switch on the power amp input jack is bad. You can try increasing the spring tension, but frankly these jack are poor quality

You could run it that way with a short cable or open the unit to do the repair.

SOMETIMES the handle screws must be removed as well.

I have taken a lot of these out and the key is to figure out which direction it comes out... MOST are out the back and sometimes a board across the back has to be taken off with four screws to clear a transformer.

FIGHTING getting the thing out when it catches on the Tolex covering is the USUAL problem. Takes patience and sometimes a blade to hold the Tolex back.

USUALLY the speaker baffle stays in place.

... do you, by any chance, have non humbucking pick ups on your guitar? Just curious...
