Hartman SFZ Two-Stage Hybrid Fuzz:
The Hartman SFZ hybrid fuzz face pedal brings two classic fuzz circuits together in a single guitar pedal. Starting with a pair of meticulously crafted clones of the original Dallas Arbiter Fuzz Face pedal circuit, the SFZ stacks 2 stages of fuzz end-to-end using gain-selected Germanium and Silicon transistor pairs. N.O.S. (new old-stock) Germanium and current-production Silicon transistors are selected for optimal leakage, gain and tone.
Each fuzz stage has its own Fuzz and Volume controls, heavy-duty true-bypass footswitch, LED indicator. Stages may be selected individually or combined as a pair for greater depth, detail, tonal coloration and sustain. Both fuzz stages respond exceptionally well to touch, player dynamics, changes in guitar volume.
Split internal 18v power using (2) 9v cells permits mixing and matching carbon-zinc and alkaline batteries for different fuzz tones. Alternatively, the SFZ can be powered via its external 18VDC power jack (see details below under Features).
The bias and texture of the Germanium and Silicon fuzz circuits can be adjusted separately via dedicated internal bias trimpots.
