New Shop

After quite a few months of renovating, we finally moved into the new shop. This building was once a welding shop and a pinball repair shop before it sat empty for several years. Here are some before and after photos.

Making of the Reclaimed Wood Therevox

I’ll admit that I’m a bit of a pack-rat, especially when it comes to nice pieces of wood. When I’m milling the rough Walnut to make a Therevox ET-4, I’m often left with an assortment of small pieces and I keep every single one of them. After four years of saving these pieces, I thought it was fitting to build a new Therevox ET-4 out of the wood left from construction of all the previous instruments.


Hundreds of small strips were rounded up, measured, graded and then milled to proper dimensions. The order of the strips and grain direction were decided on and then the strips were laminated together.


Each side of the instrument is made with a six-layer lamination. It wasn’t intentional, but I like the coincidence that this instrument is also the first of our sixth production run.


Wiping on the first coat of Tung Oil is always the most anticipated part of building these instruments, and I was especially pleased with how this special instrument turned out. I was honoured when the guys at showed off the final product at MoogFest in Durham, North Carolina.


To be honest, this was an instrument I wanted to keep for myself but I already own one of the first ET-4’s (serial number 1 – 12). It was listed on for only several hours before it found a good home at The Loft Recording Studio in Chicago.


Wood & Wires – Documentary on Therevox

Over the course of the last year, Detroit’s Spokeshave productions came and visited Therevox Custom Musical Instruments to film the progress of the ET-4 instruments being built. The final video turned out great, and I’m happy to share it here. Intro music by Team Me.

Tech Talk: Therevox. June 26th


If you’re in the Windsor/Detroit area, I will be speaking at HackForge on June 26th at 6PM about Therevox, showing some early prototype stuff and demonstrating the ET-4.3. The event is located at the Central Branch of the Windsor Public Library, and more details can be found here.

New Therevox Expression Pedal

This one has been on the back-burner for a while, and I’m happy to say that it is finally done! When we designed the ET-4, we always expected would be used with an expression pedal full control of the sound (pitch, amplitude and timbre). While most off-the-shelf expression pedals will work fine, we designed this pedal to be a perfect complement to the instrument. Included is a 5′ cable that we’ve made using high quality jacks and vintage reproduction cotton overbraid cord.
