Been noticing some hiss coming out of my amp that occurs when I'm palm muting, tried my Telecaster and Les Paul little more noticable on the Telecaster, any ideas what it could be?
It occurs just when you are palm muting? Can you record just a sound clip? Are you using a high-gain/high-distortion sound?
Single coil pickups and high gain settings. Lower the gain to as much as you can tolerate it and read up on the amp manual to see if you can attach a noise gate to the patch (if it has one).
it can happen even on a clean channel too, used the noise gate, did some messing around it's bit more bearable now. Looking at getting a new amp anyway.
Could be the "snare hiss" that Valvetronix amps have had in the past. One of the reasons I got rid of my VT20.
That's what I'm thinking it is as well.
