Info about the original:
Apiformis Fuzztortion is a pedal that is quite unlike it’s original idol. In it’s heart, it is a dark low medium gain fuzz/distortion that has delusions of grandeur about being an overdrive. And it is doing all that with vintage-like touch, from doomy dark to brightly overdriven, distorted fuzz with vintage, medium sustain.
Apiformis has three controls for tuning the tone to your preferences:
FEED: Controls the load on the input (impedance). From dark, low saturation (0) to medium fuzz (5) and finally full sustained distortion-like fuzz (10). Lower settings can lead to oscillation, which is a feature.
TREBLE: Controls amount of higher frequencies boost on the tone. From dark, nearly muddy (0) to open higher mids (5) and finally to fully boosted top end (10).
LEVEL: Controls the output level of the effect. Level at zeron means that there is no signal passing through. Unity level with bypassed signal comes in with knob on ~11 o’clock. There is plenty of room for overdriving your amp with higher settings of Level control.
