From Sonus:

Sonus 1968 Germanium 'Jimi Mod' Fuzz Red Dot
(Newmarket)
1968 Fuzz with the modifications Roger Mayer did for Jimi. From dive-bomb- tones to soulful treble boost, this pedal is one I am definitely proud of. Great volume knob response and sensitivity to your dynamics, together with the controls on the box itself insures an almost limitless variety in tone. This one will keep you playing and discovering new tones every day!

I offer this pedal in a small pedal-board friendly enclosure with DC IN and jacks situated on top for practical purposes. It comes with NOS Newmarket transistors and a bias control. The bias will allow you to regulate the voltage between the transistors and in doing so fine-tune / re-bias the fuzz after extreme temperature changes or to get a different tone and tweak it exactly as you want. The bias control will let you achieve any tone between a cold sharply spluttering fuzz to full, round and muddy.

Every Fuzz I make is thoroughly auditioned on a variety of amps, until the right transistors are found and the correct bias is achieved.
I use an exact replica Arbiter issue 1 PCB and new old stock (NOS) made in England, New Market transistors.
