Keeley Electronics Unveils the Tesla MKIII Germanium Fuzz

A vintage-style fuzz built with 1970s Soviet-era 104NU71 germanium transistors.

Edmond, OK​ (June 21, 2017) -- Keeley Electronics is proud to announce the Tesla MKIII Fuzz​, a vintage voiced MKIII Soviet Germanium fuzz with Keeley attention to detail.

With controls for fuzz, tone, and level the Tesla Fuzz makes it easy for players to dial in very wild amounts of fuzz. Modifications to the circuit allow for an increased high frequency not heard of before as well as ultra-low noise. Furthermore, design modifications have solved temperature problems that can affect vintage fuzz units. This particular bender design has a very vintage tone to it. Pure fuzz, no overdrive. Think late 1960s and very unrefined.

“Our design team focused on building a MkIII style circuit with a stash of 104NU71 Soviet transistors that Keeley obtained. In this particular NPN Germanium design we focused on bringing out the most amazing attributes of the transistor. The 104NU71 has a super sticky, velcro tone and an incredibly unique bass response” said Robert Keeley, founder and chief engineer, Keeley Electronics. “To achieve this, we employed several technical innovations from our Time Machine Boost and Holy Fuzz designs. We also use techniques to nearly eliminate temperature coefficient problems in germanium designs.”

The Keeley Electronics Tesla MKIII will be released June 22nd. Street Price is $149.
