Groove Tubes?

How can you get a great tone without a good understanding of what makes your amp tick? — EL34, EL84, 6L6, KT66, KT88, 12AX7, 12AT7, 12AU7, EF86, Output Transformers, Power Transformers, Capacitors, Resistors and everything else that it takes to make a tube amp sing!

Groove Tubes?

Hey guy if you read my post that I wrote about my Super Bass finally sounding good, you see that I swapped a set of Groove Tubes for the EH EL-34's.<P>Has anyone else had such a miserable time with Groove Tubes? Even after I rebiased the amp, and put the Groove Tubes back in, it still sounded horrible! Are Groove Tubes just bad tubes in general?
Interviewer: So Jimi, what's it like being the greatest guitarist in the world?

Jimi: I don't know, ask 1965Strat.

I couldn't believe it either!

Grrove Tubes just matches and relabels tubes, they don't make them - so the tubes could be from anywhere (probably Chinese). I've used some that worked fine in the past though for the past few years I've stuck with Svetlanas (EL34s). I think you mentioned that you rebiased for the other EH tubes, and Hamilton seemed to think it was running a bit hot, so maybe the Groove Tubes just weren't happy at that bias setting and hence sounded crappy - (GT has a rating system based on how quickly the tubes break up, what were they marked?).
Never let the music get in the way of the stage act...
