My Remedy produces a nasty, fuzzy overtone on low bass notes (generally anything played on the low E string from E through G#). I've spent the last few weeks trying to figure out the cause of the tone, systematically swapping out each part of the signal chain (speaker, speaker cab, cables, etc.). This also includes systematically replacing all the preamp tubes (one by one, and then the whole set), and even the power tubes. Nothing has solved the problem. The tone generally shows up on the attack of the note and then re-emerges once again on the decay. It's really evident on single notes, but can be heard even on chords (primarily during the decay). Turning down the guitar volume attenuates the overtone; at around midway on the pot it disappears. The amp's tone controls don't really do much to the overtone; it becomes more noticeable as the volume goes, particularly the High, but it's still there no matter how I set the volume controls. Tonight I ran the amp into a Palmer speaker simulator and recorded some examples. I started with the guitar volume down, picking the open E and then turned the guitar volume up. I then hit a couple chords to demonstrate the effect on the decay. The amp is only about a year old (though a pre-MV version so my guess is that it was sitting unsold at the dealer for a while before that) but clearly has something wrong with it. I'm in Europe (Germany to be exact), so shipping the amp back to the factory isn't an option...

I finally solved the problem though I'm not sure why it worked: I cleaned all the tube sockets with some CAIG De-oxit Gold and the odd ghost notes have disappeared.

Gotta love a simple solution! Todd
