The Stoll Effects 68 Fuzz is a handcrafted German boutique fuzz pedal: an analog fuzz built around two carefully selected NOS germanium transistors, including a rare UK-made NKT214 and a Mullard OC44M. RockBoard's PedalPedia describes it as inspired by classic rock fuzz circuits but reimagined for modern players, delivering "raw, biting, and lively fuzz tones that cover styles from country grit to classic rock and stoner fuzz"1.
The circuit and what it does
The 68 Fuzz is a germanium fuzz, a design family prized for its softer, more touch-sensitive clipping than silicon designs. Stoll Effects builds it with two NOS (new old stock) germanium transistors, meaning vintage parts that were made decades ago but never used: a UK-made NKT214, which the maker calls rare, and a Mullard OC44M. Those transistors are paired with vintage capacitors1.
The maker positions the pedal as a take on classic rock fuzz circuits reworked for modern players, covering everything from country grit to classic rock and stoner fuzz1.
Controls and switching
The pedal keeps its control layout simple:
- Bright switch: lifts highs, giving a brighter voicing on top of the fuzz1
- Soft-touch footswitch: RockBoard's PedalPedia describes it as "a soft-touch footswitch for everyday usability"1
Power and build
The 68 Fuzz runs on 9V DC, center negative, the standard polarity for compact pedals, so it fits a normal pedalboard power supply1. The circuit is analog throughout, and the pedal switches with true bypass, so the fuzz is entirely out of the signal path when off1.
The housing is brushed stainless steel with handcrafted screen printing, in keeping with the pedal's handcrafted, small-batch construction1.
Germanium transistor pedals like this one are built around vintage NOS parts. Because those transistors are finite and individually selected, each pedal's character can vary from unit to unit, which is part of how the maker presents the design1.

Questions
Is the Stoll Effects 68 Fuzz true bypass?
Yes. The maker lists the 68 Fuzz with true bypass switching, so when the pedal is off your guitar's signal passes through without the fuzz circuit in the way. The pedal is switched by a soft-touch footswitch, which the maker describes as being chosen for everyday usability.
What transistors are in the Stoll 68 Fuzz?
The 68 Fuzz uses two carefully selected NOS germanium transistors: a rare UK-made NKT214 and a Mullard OC44M. These are paired with vintage capacitors, which the maker says help deliver raw, biting, and lively fuzz tones.
What does the Bright switch do on the Stoll 68 Fuzz?
The Bright switch lifts highs. It gives you a brighter voicing on tap alongside the pedal's normal fuzz sound, useful for cutting through or tightening the top end without changing pedals.
What power supply does the Stoll 68 Fuzz need?
The 68 Fuzz runs on 9V DC with a center negative plug, the same standard supply used by most compact pedals. Use a regulated 9V DC supply rather than an AC adapter or a higher-voltage output.
Where is the Stoll 68 Fuzz made?
The Stoll Effects 68 Fuzz is a handcrafted German boutique fuzz pedal, built in Germany in a brushed stainless-steel housing with handcrafted screen printing.
