Are my tubes doing what they're supposed to? (Guitar amp content)
Sorry in advance but this thread is going to be about a guitar head, not a bass amp. I don't frequent any guitar forums and I figure the difference between a tube bass rig and a tube guitar head is probably quite minimal. I use this amp for bass anyway so it's not like the scenario is totally disconnected.
So, I've got an Egnater Rebel 20 amp head, currently running on a Vox 112 Night Train box. It's an exceptional guitar amp for a guy sharing a little apartment. I really like it.
One of the features of this amp is a knob which allows you to select which tube stage to use. It's got a pair of EL84s and a pair of 6v6s in the front end and the knob allows you to use either pair of tubes separately, or use any blend of the two. It's a pretty cool feature which was one of the main reasons I picked up this amp.
My problem is that I'm not certain that the 6v6 side is doing what it should be. I get a really ballsy, punchy broken up tone when I roll to the EL84s which I really dig, but the closer I roll to the 6v6s the less exciting the tone sounds. It really backs off, becomes quite hi-fidelity and thin, output and punch is lacking and it just sounds scarily like a solid-state. I initially still used that side of the amp to get really crystal cleans, but recently I've been finding that I'm still getting a much better clean tone out of the EL84s for almost any tone I'm chasing after.
Does this sound like normal behaviour for 6v6 tubes? I bought the amp secondhand about 2 years ago and I've never really serviced it. This is only my 2nd tube amp so I'm not positive what to expect out of all different tube types.
Cheers. And sorry this doesn't relate directly to bass.
