ARF66 Fuzz by Rhodium Electronics approach to the Tone-Bender Vox MKII re-issue with two germanium transistors. A Fuzz-Face circuit modification setup with a selected pair from our military grade sealed boxes in stock of 1T308V vintage early 80's Eastern Europe germanium transistors. Built in professional prefabricated PCB, setup with audio grade and high quality standard electronics components. Noiseless. Top mounted jacks and click-less true-bypass switching. Requires of isolated PSU 9Volt negative tip. Battery free pedal.

ARF66 Germanium Fuzz is a take on the classic Fuzz-Face circuit, modified following different concepts and variants of the original design. Built in small runs in order to standardise every small batch in order to achieve similar features of the germanium transistor family selected from our stock. 

This effects pedal is not just another clone of the Dallas Arbiter Fuzzface, designed in order to bring the fuzz distortion range and bandwidth from the Fuzzface to the Schaller and Vox Tonebender MKII reissue (with two transistors) and Analogman Sunface/Sunbender, and song machine fuzz territories. 

Just a few tweaks added to make these equivalent of the NKT275 transistors much easier to use and sounding far better, adding an internal pre-set bias control trimmer potentiometer, which it offers accurate adjustment for dialling the final bias by ear, and useful to achieve more of a gated fuzz responses too. The internal carbon Skeleton trimmer brings the essences and myths of the carbon composite resistors to the guitar signal in this modern circuit. Trimmer pot been setup to the 60s fuzz spot, about 4,5 Volts on the higher transistor. These skinny metal capsule germanium NKT275 transistors were produced back in the 90’s, in the USA. 

Top mounted jacks, vintage true-bypass, no loss of signal when disengaged. External power supply socket, please, use only dedicated PSUs 9 Volt negative tip, or isolated power supply stations with 9 Volt centre negative polarity. Do not share the power supply with normal effects pedals. 

This unit is battery free and low noise, offering an excellent signal to noise ratio. On top, Volume and Fuzz controls need no explanation. This Toni-Bender MKII revision 1.5 with NKT275, or equivalent, features a particular clean-ish sound when your guitar volume is rolled off. This unit has been professionally assembled and biased at a stable 20*C degrees room temperature with a nominal voltage. 

Note that all vintage germanium devices work at their best at about 20*C degrees. Therefore, the internal bias trimmer pot allows it to sound similar at any temperature when is setup to the same biasing voltage.
