The Deimos project is identical to the original Tone Bender Mark 2 except for a couple of enhancements. First, a voltage inverter circuit has been added so you can use PNP transistors with a standard 9V supply. Second, it includes trimmers to more easily dial in the optimal bias voltage.

This kit contains the PCB and all necessary parts. The enclosure can be selected, please select 2 knobs for 6,3mm shaft separately.

This project is by Aion Electronics, in collaboration with Musikding. If you have any problems with the contents of the kit, please contact Das Musikding (Klaus). Since the modifications require some basic knowledge, this project is rather for more experienced builders.

5 from 5 Great no-nonsense ToneBender MKII

Got the kit with the pre-drilled box. Very happy with the pedal, however I have a few suggestions to consider before building.

I got a matched set of AC125s, which were nice! They biased pretty easily without much hassle.
Sounds great, proper ToneBender MKII fuzz.

The kit comes with PNP-NPN voltage inverter chip TC1044S, this IC is also suggested in the build docs. However, I found the IC to cause a whining feedback when used with a power supply (CIOKS DC5, OneSpot and HB PowerPlant Jr all did this). Luckily I had a spare ICL7660S which got rid of the noise.

The pre-drilled box did not have space for a battery, but you could fit one if you drill the box yourself. Worth considering especially if you are planning to build it without the voltage inverter.
