eZone53 Tone Bender Mk1.5



This is a reproduction of the British made Tone Bender MK1.5. The originals were built in the 60's during there transition between the MKI and MKII so there was not very many of them made.

The MK1.5 is considered one of the best by many fuzz users. With its sonic capabilities, huge amounts of woolly fuzz, more mid range, tons of sustain and it's ability to control the amount of fuzz with the guitars volume.

This reproduction has the exact same component values as the original MK1.5 of the 60's that can cost around $700.00 or more for an original if you can even find one.

The pedal is equipped with 2 MULLARD/PHILIPS Germanium Transistors OC75 in Q1 And OC76 in Q2.

Each transistor is carefully tested for the correct gain and the least amount of leakage to create the exact tone character and breakup of the original units.

BC Philips Caps are used along with Carbon Film Resistors.

The enclosure is a Hammond 1590N diecast aluminum enclosure that has been Powder Coated with a tough Silver Hammerite finish then silk-screened.

eZone53 about the version with bias control

This reproduction has the exact same component values as the originals except I replaced the 47K collector resistor with a bias trim pot to the outside of the pedal so you can adjust the level of voltage going to the transistors without having to open up the box.
