Not bad for 5 watts into a 1x12 eh?
The only EL34 that I have ever tried in my Picovalve was a JJ's 6CA7. Alas, after many long years of service, it finally gave up the ghost a few months ago. That's when I put the KT-77 in. The KT-77 has, to me, more mids than a 6L6. It doesn't have as much low mids as the 6CA7, but more than a 6L6.
What I really think helps with the clarity is the 12DW7 in V1. It cuts the gain, but given how much gain I can possibly add if I want to, it keeps the top end from getting too fizzy and the bottom from getting too flubby.
Of course the pickups play a big part because the Fuglies are remarkably clear, while still being very loud for an A2 low wind pickup.
Thanks for the well wishes!
