No. If you're going to store or display a guitar and not play it, its good practice to slightly ease the tension of the strings to prevent warping. Either way, you'll want to keep moisture and temps in mind to prevent neck warping

Why not un-complicate the circuits by eliminating the soundboard first?

but you would have to go to Peavey direct for service info.

https://www.allaboutcircuits.com/textbook/direct-current/chpt-14/electromagnetic-induction/ The AC power changes the magnetic field and may be being picked up in your amplified leads . Or the DC voltage in your amps power supply is not filtering the power after it rectifies the AC power .A really big capacitor across the dc voltage output from the rectifier should filter any AC out. https://www.allaboutcircuits.com/textbook/experiments/chpt-5/rectifier-filter-circuit/

Normally on older Peavey amps the grill is on a frame attached to the face held on with velcro. I suspect you have something vibrating against the speaker if it's only one frequency. Once the grill is off it may be apparent. Also on old Scorpions and Black Widows Peavy has a piece of foam in the hole in the magnet to keep junk from getting in the speaker. Over time it crumbles and opens that hole, but even worse can get it the gap and freeze the voice coil. I always suggest cleaning it out while the speaker is out of the cab.

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.

I think you may have a bad input jack, or it has come loose from the circuit board.. If you need to take it to a repair shop, ask about their bench charge. It may be cheaper to just replace the amp.

Not sure about the KB-1, but many newer Peavey amps ( A Vyper for example) have the fuse soldered to the circuit board. If you're going to go through the effort of soldering, I'd suggest buying, and soldering in, a rear panel accessible fuse holder, so you only need to do it once.

simple !! most peavey mixers have a monitor output !! you can use that to feed new amp , and theres your volume too !!! or if your already using the monitor output , you can buy a split cable (1 in 2 outs) for main send !! this cable would have to be kept short or it will induce HUMMM !! and in real extreme cases if your using a low Z send (cant think as to why ) a device known as a (direct box) normally used by instrument sends can be used in reverse to "tap" into a low Z send and output with a unbalanced send for an amp to your other room , but hey why not just add a speaker with a volume control to it for this smaller room ? and forgo the new amp
