Okay so I have a Crate GT1200H Halfstack, Its a **** solid state...but it's getting me by until I can afford my Peavey Valveking head......so dont rag on the head, becuase I dont feel like getting this topic hijacked to all the reasons my Crate Sucks.... , Now that that is said..Hers my problem...If I have my cable plugged into my amp...and into my guitar all is fine...But if I pull the cable from my guitar, the amp makes very loud humming(not like pickup humming, like the sound you get when you put your finger on the end of your cable)....and you have to unplug the cable from the amp to get it to go away (or plug it back into the guitar)..And also, when you unplug the cable..if the amp is loud enough, you get a high pitched screeching sound....Could my speaker cable be bad? I JUST bought it....from musiciansfriend....Any Ideas?


Thanks.

There should be some noise with the cable unplugged from the guitar. Its normal on all guitar amps. The squealing at high volume is normal as well.

I have a Crate GTD65, and mine has this bad habit of producing feedback at high gain or just plain old high volumes. And the screech when unplugging is normal, I think.

i don't think the crate gt series sucks its actually pretty good for solid state.
the screeching you're hearing is completely normal.
why would you unplug your guitar while the amp is still on anyways? it takes two seconds to turn the power off.

The high pitched screeching is electromagnetic feedback, probably caused by microphonic pickups. It happens more on SS amps than valve amps. You could try getting your pickups potted.

If you read his post, he says he get's the high pitched screeching when he unplugs the cable. Thus I don't think potting his pickups would help.
