Deimos MK II Tonebender

Project: Deimos (Tonebender Mk II)

Build description

Trapezoid box from Mouser with toner transfer graphics topped with orange alcohol ink and several coats of clear satin. Trannies are a matched set of 2N404s from LIC Pedals. All other parts from Small Bear. Like all the aion boards I’ve built, this was a piece of cake. Nice vintage fuzz tones.

Tone warp

Project: Deimos (Tonebender Mk II)

Build description

Easy to build
I got my OC75s from smallbear and with them came replacement resistors for certain parts. I tried it first with the resistor values as per the schematics but it didn’t sound right no matter how I tried to bias it, but after replacing the resistors the sound was amazing. I had to change R1 to 5k so that I could get Q1C to be high enough. The only other modification I did was to change R5 to 1.5k so that the output volume would be louder.

Modifications or part substitutions

R1 5k
R3 15k
R4 120k
R5 1.5k
R6 6.2k

COVID-19 Lockdown Pedal Build

Project: Deimos (Tonebender Mk II)
Variant: OC81D TBII with Shape and Boost

Build description

On lockdown I finally had the time to work of a project for myself. I’ve always wanted to build a single grab-n-go pedal that pursues the tone of my favorite guitarist. As a tribute to Mick Ronson, I built a 3-in-1 pedal beginning with the Aion Chroma that mimics the cocked wha that Ronson used at the head of his chain.

The Chroma build in this pedal uses a 3PDT toggle switch as this will be a “always on” effect in the chain. The throw I located above the potentiometers. As a side note, I finally have it down to 5 minutes to assemble the special 10K A/C Dual Pot. After pulling off the back, I use a drill with with a good metal bit to drill the top of the post that keeps the plastic from being able to slide off the end. I hold it upside down in my hand (being very careful) so the metal dust and plastic shavings fall away from it. Once I see that the post end is actually round, the plastic just slides off and doesn’t have to be broken apart into tiny pieces. I built a surplus of 10 in less than a hour.

In position 2, I decided to hit the TBII with the Aion Radian (Dallas Rangemaster. The space I left below the board will be for a future idea that may or may not work. The 3p Lemo connector in the corner is for the future plan of using a servo motor to drive the boost. In a separate pedal, I’m building a Arduino based project that will allow me to set amount and time that the boost will swell with a single stomp… I suck at playing and using my volume together… or a pedal. Once I get that worked out I’ll dress my wiring better. The Radian uses a Yellow Jacket Mullard OC44 and sounds absolutely amazing. I almost use it “always-on” but use a standard 3PDT located below the Chroma board.

The two finally lead to the Aion Deimos. I wanted to leave myself options for what transistors would be living on the board so I used sockets for the leakage sim resistors. Ultimately I didn’t need them but I’ll always have that option. I went with a 100K in R1 (also socketed) because I used OC81D’s. I wanted to knock it out so I had to use a 4PDT because I ran out of 3PDT’s.

This was the first 3-in-1 I built and wasn’t sure it would work but it did. I fired it up for the first time and ever thing sounds insanely good. When we can finally leave our homes, I can take this one pedal and be good to go. Hope you’ve enjoyed the report and are staying safe and well during these crazy times.

Tone Bender Mk II

Project: Deimos (Tonebender Mk II)

Build description

I built this with a set of Texas Instruments 2G303 (PNP) transistors from Small Bear (http://www.smallbear-electronics.mybigcommerce.com) and used a 7760S charge pump to provide positive-ground. Biased properly, this circuit is the platonic ideal of fuzz.
