Keeley Electronics Limited Run Tesla Mk III Soviet Fuzz Bender

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 1960’s 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 paricular 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. End result is that Keeley Telsa Mk III Soviet Fuzz Bender is vintage fuzz in the whole world. We are extremely proud and excited to give our people in very economical limited edition!”
