sas6.JPGFryette left VHT, kept his circuits and started Fryette where he primarily builds amps. He has done a small line of tube based distortions and I guess they haven't sold well, this was on sale at GC when I stopped in and for an EF86 based pedal running at full voltage, I had to take a look! There are a couple of reasons I believe his contention that this is a high voltage tube: one is that it doesn't pass signal at all till it has time to warm up (unlike most "tube" overdrives which use the tube for color in some kind of parallel arrangement with diodes or op amps). Secondly, it uses a 12v AC power supply and there's that chunky transformer in there to bump it up to whatever he felt was needed... There's also a fairly stout looking set of power supply caps there. Anyway, the middle knob is bias rather than tone. It seems to pass the most volume and bass in the middle setting, so I'm guessing for this particular tube it's underbiased (cold) to the left and overbiased to the right. It gets thinner and more distorted at the very left. The other knobs are Gain and Volume. Gain goes from crunchy trails on the ends of notes to really heavy distortion. Volume goes from normal with the distortion up above midway and the volume at maybe 9, to REALLY, REALLY loud and punchy with the volume above that. This is a ridiculously loud pedal! The distortion is harsher than I really like, maybe due to being a pentode? or maybe because it's a Sovtek EF86, which doesn't have a great rep. I think I've got a Mullard around here somewhere I might try... Oh yeah, why do folks who use the square, cutout 9v jacks put them opposite the footswitch so you've got to bend the PCB to get the footswitch out and disengage the 9v from the cutout?
