SPL is spot on, you want to put as much distance between the guitars and the amps they are plugged into as possible. Never let the guitars face the amps. Also, avoid hollow body guitars !!!!

Try turning your guitars down when you are not playing (using the volume pot on the guitar). This may not do much for your long sustained notes but it will be better than defining people. If you are using an LP type guitar you can set the vol to "0" on the pickup you are not using and use the PU selecter switch as a kill switch, turning everything off instantly. You can also buy cable with a kill switch built into it.

If this don't work then you can solve the problem with either a gate (expander) or a feedback destroyer. You can pick up a second hand Behringer noise gate for about 20-60 bucks on eBay.

Remember what feedback is, it is the guitar picking up signal from the amp feeding back to the amp being picked up by the guitar.

Break the loop you solve the problem (Oh how very Zen of me !!!).

G'luck dude !
