“Darkvoice 337: Introduction A little background: the Darkvoice 337 uses the 6AS7G dual-triode for its power/output tube which, while definitely delivering that special touch of midrange magic that I personally only experience from tubes, it is a far less syrupy tube than many.

Edit: I upgrade a few parts inside (power resistors and output coupling capacitors) and now I can vouch this amp is world class! Such a pretty sound and power, it is scary good! ” --telecaster
“ I was lucky enough to pick this critter up from the FS/FT forum for a good price (thanks!). After spending a little time with it, I have to say I'm pleased. I've tested it with my Beyer DT770pro/80ohm and Senn HD205. Didn't do much for the Senns, but the Beyers seemed to become tighter and more responsive.
