Man if I had to speculate it's the combination of all 3
I do think the Badlander has very responsive TMB / presence adjustments and with a GEQ in the loop it allows further compensation. The denser 6L6s do add to the overall thickness, but in a good way and there's alot of control to play with. Will have to spend a bit more time playing around with the EVM Thiele and the 6L6s, it's a different tonal take that is pretty cool.
Yea man, no doubt. That's exactly where I ended up as well, for now. Went as far as creating a Clean Fender amp patch and bypassing the preamp, which worked out fine, but the inhertent clean voicing continues to grow on me.
I used to have BBkr PROs in one of my LPs, but swapped them out for PAFs. I do recall the PROs being gainier but it doesn't explain why they wouldn't clean up like they do with the other amps.
FWIW my #1 LP has Fishman Classics, it has a SC switch option and that really thins out and cleans up nicely without sounding too weak. I don't use the SC option alot with the other rigs, but it's really nice with the Badlander Clean voicing.
