Hi gang,

I'm looking for recommendations on tube brands for my guitar amp.

I use the Atomic Reactor AR112-50. This is a modeling amp with a tuned
speaker and cabinet. No preamp section. The POD is the preamp. This amp is
designed to be neutral in tone so that any digital amp/cabinet modeling
scenario in the POD or floorboard is accurately reproduced and warm'd with
tubes. The POD plugs directly in the power amp. It has two 6L6GC for
power and a 12AX7 (phase inverter).

Is there a difference between a 6L6GC and a premium JJ 6L6?
Is there a difference between a 12AX7 and a 12AX7A?
Any recommendation on a brand for mid/top quality clear and clean neutral
tone? The 6L6 should be a matched set.

I use the Line6 Variax guitar and use Tele, Strat, LP and acoustic models.
The LesPaul and acoustic models carry a lot of low mids and I notice the amp
seems to break up when I pick or strum the 3 low strings when at stage
volume. The tubes have 1-1/2 years on them and roughly 500 hours of use.

On a slightly off topic, does the feedback sounds or tones come from the POD
or is it a function of the amp's phase inverter and power tubes? I always
thought that it was a function of the guitar pickups and the sound from the
speakers being reinserted back into the guitar pickup. But the Variax has a
strange pickup. The pickup is in the bridge (where the string actually
touches, much like acoustics) yet I am able to turn towards the amp and
still get the traditional feedback loop thing going on. I don't get it. Is
it possible to continue to get tubes that don't break up but still offer the
feedback loop, or is it a compromise?

Any thoughts or recommendations would be appreciated. Sorry for all the
questions.

Thanks,
Wayne
