A circuit that takes advantage of the shared topology of the MKII and MK1.5 Tone Bender for a versatile 3-in-1 fuzz / boost. Use both channels independently or stack them for a true MKII Tone Bender.
The fuzz channel is an authentic reproduction of the Sola Sound MK1.5 Tone Bender featuring new old stock components and a curated selection of germanium transistors (see options below). The circuit is true to the original with the addition of an external bias control that modifies the clean-up and character of the fuzz for a range of classic and eccentric tones.
The clean channel is a germanium boost based on the input stage of the MKII Tone Bender. An added 3 way EQ switch and gain knob give the circuit control over the frequency range and gain of the signal being fed into the fuzz channel. The circuit is responsive to changes in guitar volume and adds a warm vintage character to any signal. Use it to push your favorite tube amp or stack it with an overdrive.

TRANSISTOR OPTIONS
All transistor options are new old stock germanium transistors dating from the early 1960’s to the late 70’s.
1974 Texas Instruments // 1970’s Mullard CV - a pair of mismatched 70’s mil spec germanium transistors. Medium high gain. Low noise. Chimey and articulate.
Mullard OC series // Mullard GET - a hybrid pair of 1960’s black glass and metal can Mullard transistors. Medium low gain. Excellent clean-up.
Mullard GET // Mullard GET - 70’s Mullard germanium transistors manufactured in the UK. Medium gain with exceptional clean-up.
New Market NKT // New Market NKT - a close cousin of the New Market NKT275 transistor used in the earliest runs of Fuzz Faces. These early 60’s New Market transistors are highly regarded for their touch sensitivity and harmonic complexity.
Equipped with a standard 9V DC jack. This product uses vintage PNP transistors which require an isolated supply.
