V1 is both channels, V2 and 3 are channel two, V4 is channel one, V5 is FX loop, V6 is phase inverter. IIRC

Brutal.

Mineral oil after cleaning with finest-grade steel wool.

Channel One is super underrated for the brutal tones.

What do y'all do when storing an amp long-term? Remove tubes? Anything else?

I haven't experienced that on mine.

This. I got the EL34 version specifically so I could run EL34s, KT88s, or a mix of the two.

What are the serial numbers on these? My Rev 2 (#336) has a presence control that is also more like a mid control.

I’ve really liked the JJ E34Ls in amps with a lot of top end on tap.

I think it got hacked years ago and they just haven’t gotten around to fixing it.

Agreed. The Twin Jet was disappointingly flubby and kinda sterile. The UU dominates it.

It can take a boost very well in Uber mode on Channel Two, but it really doesn’t need it when dialed in correctly.

With the right tubes, it can do anything the earlier Ubers can do and a lot more. It’s by far the tightest, most aggressive version of the Uber ever, and it has surprisingly nice clean and crunch tones. That said, I can’t stand the Uber power amp mode or the Bright mode on Channel Two. Pretty...

I’ve also tried a mix of JJ KT88s and JJ EL34s. It definitely cuts the mids and boosts the low and high end, which I’m fine with because the UU is a very mid-focused amp. It also makes it ridiculously aggressive and tight. I think I prefer this combo the most.
