I have a T-Rex Reverb that makes strange warbling/hising noises, and I'm wondering if this is normal. It isn't coming from the guitar or the MV spot lights that generate a lot of rf noise, and I don't think it is the power source. Also the noise doesn't change with the pedal settings, except when switching between "modern" and "spring". I did discover that it is only occurs when the amp is turned up bright, so it might not be noticed at warm settings For example, I can't hear it on my Epi VJ at unmodded or moderately bright settings, but I can when I switch it to very bright. Likewise on the H&K Dual EL84, a bright amp, it is very obvious unless I turn both the mids and treble down.

Thanks for any insights.

The plot thickens. I took it down to my mate's music store, and tried it with a different power source and a battery through a Fender Twin, set bright. No problem, it worked perfectly. My mate gave me the power source to try at home. The problem returned, just as noisy with a battery and the new wall wart as it was with the old one. I wondering if it has something to do with that amp. - An H&K Statesman Dual EL84.

Any ideas?

Dirty power? What kind of power supplys did you use? Also, try it with a battery and see if it still does it at your house.

Thanks. It is the same with a battery or two different wall warts, through my two amps set bright, in my music room. No problem through a Fender amp in the shop. I think I'm going to have to to take the pedal and my amp down to the shop as the next move.

It's a decent spring reverb sound if I can ever get it to work for anything livelier than smooth jazz.
