Time to re-valve my VH4... KT77 or EL34?

I'm just gonna confirm your gut feeling here, but since you both like the tones your having now, and based on your musical direction, I don't think the EL34 will sound better. They'll probably just make your clean sound a bit smaller and compressed (my opinion).
Stick with the 77's!

What you're describing you want el34's, seriously. You need more of the valve compression and break up that el34's will provide. It's what I don't care about 77's they're too clean and smooth.

I have a 2001 VH4 that I re-tubed with Gold Lion KT77s about a year ago. Killer. More 3D than EL34s in my opinion, but at the end of the day I felt the EL34s cut through in a band mix a little better. Just switched back to EL34s.

Which EL34's?

I have used Siemens EL34 and SED EL34. They are sharp and have a good cutting top end.
I usually bias the EL34 in the VH4 to 30ma or 60ma a pair. It gives them a bit more room to rise and does not compress as quickly when pushing the power amp. If you have the money and want the best of both worlds, a NOS quad of Sylvania 6CA7's sound ungodly in the VH4. Big balls and a little compression when pushed. Try to run the bias a little cooler than 35mA and the amp will run a bit cooler. To my ears it sounds good especially when the amp warms up. A Diezel is at it's best after about 30 minutes of warm up or playing.

Cool thanks for the input. I also have found that speaker cabinet (as opposed to just speaker selection) selection is super important with the VH4.
