This is a "Deluxe" version of the Scarab with more control over "feel" and adjustments in bias.
This version adds in a couple knobs over the 3 knob version.
A straight ahead refined vintage era fuzz along the lines of the Tonebender with lots of sustain and gain.
Tone control smooths out the high end but is very usable at all settings.
All gain and tone settings remain articulate and sweet throughout their range.
Full fuzz sound with the clarity of an overdrive.
Read the Scarab description above for the main attributes.
Tonebender type circuits vary depending on the bias of the 3rd transistor. Gritty gated tones on one end of the dial, sustaining lead tones in the middle and sweet lower gain tones at the other end of the rotation. Bias affects tone and gain.
The low end at the input of the circuit affects fuzz amount and saturation. The feel of the pedal can be adjusted from a saturated slower responding "fat fuzz" to a snappy, fast responding, slightly less gain fuzz that has the feel of a distortion or overdrive. This helps dial in a single coil to be fat or a humbucker to clear up a bit and be more senitive to dynamic picking.
