Yes, i was about to sell it, but since i undusted it and checked the bias currents (shit this thing is heavy), i remembered i wanted to try the cold biasing that was discussed here.
So more like 25 instead of more like 35mA per tube. This open the mids right up and the stuffiness/congestion i kind of like, but also regulary annoyed me, is gone.
Sounds more cold and therefore more evil.
It's now got a kind of mesa flavour to it (i also run an EQ in front to get more string clarity, but might have over done it)! maybe a tad higher bias would be better, but so far so good!

While i was at it, i also moved the feedback from the 8 to the 4 ohm tab.
more raw, in your face, more sizzle!

Edit: it might not be such a huge difference recorded, but it's just the lil rawness added, that makes it more alive for me! The planket over the speaker removed, so to speak

everything the same except for the feedback wire position.

both clips with cold bias, though
