Hi,
Tonight at practice the TC-50 was up to bat. All was well in channel 2, gain at noon, tight, crunch heaven. Channel 3 however, was having issues. My guitars (a PRS with Seymour duncan Mark Holcomb pick-ups, a JP IX with the Liquifier/Crunchlab set up) would both howl around when not being played, even with strings fully muted. The only other time I've experienced this was with the Rectoverb cranked, I figured it was a Rectoverb thing. When the guitars were being played, there wasn't any problem, just when stopping and holding the strings the guitars would howl.
The settings (o'clock): EL34 tubes, Channel 3 Tight, Gain 2:00, Master 1:30, Pres 1:00, Treble 12:00, Mid 10:30, Bass 9:00 , Output 10:30. Amp was on a concrete floor in a double garage. I was maybe 5-10 feet away from it. I put EL34s in before practice because I figured the extra power (vs. 6V6) would be needed with these guys (GnR, old school Metal 80s-90s). Room was pretty solid (brick, cement etc.)
Yes, the amp was loud, but not overly so. With the Mark V it can be much louder with no howling around.
Any ideas of what settings to modify (without reducing volume) to prevent the howling? I did knock the bass and mids down a bit when it first started howling, but it didn't help much.
At any rate, I love the tones out of the TC-50 so I'd like to get this to work in the future. Thanks,
Mace
