Hey guys. I've been getting a crackly hum from my guitar amp. When I start adding compression to the mix the noise shoots through the roof. I've been told that I need to use a power conditioner instead of plugging the amp straight into the wall. Is this correct? I'm only playing clean tones. Think Motown, old soul, etc. I have a tele, les paul, and a silvertone 1429. I'm using a fender super reverb and an orange thunderverb 200 w/ a 4x12 cab. So far, I have only recorded using the super reverb turned up to about 1.75 out of 10. And I placed a 57 slightly off axis about 1 inch from the best sounding speaker. My guitar tones sound thin and with a lot of hum. As you can see, I need a bit of help here. How do I eliminate the hum from the amp? And how should I set up the amp/mic? I would appreciate any feedback!!!
