The Q-Chord Omnichord

This is one of the more interesting jobs I’ve had. The Q-Chord Omnichord which is actually made by the Suzuki Corporation. The current owner of this one took a gamble on buying it in a broken state. It looked as if a previous owner had not noticed all the screws that hold the covers together and had tried to prise it apart with a screwdriver. The PCB inside had a big crack in it and the DC power input jack was mashed. I did manage to get it all working in the end though you had to press quite hard on some of the chord buttons on one row to get them to sound. They use a conductive rubber pad under the button sheet to make contact. I cleaned the pads as best I could and guessed that with use they might improve. This model has a rhythm section. The plinky plonky tune (in a key to match the chord button currently playing) that is created by touching the touch sensitive strip to the right is quite delightful.Electronic instrument

Here is a photo of another one I have just been working on: The Omnichord OM-84.

 

Kawai Keyboard Repair

Here Jennie Nell with her Kawai MP6 stage piano. It had a blown -15 Volt regulator on the internal power supply board. Nice keyboard to work on, easy to disassemble. It all powered up and showed a display because the main logic board was powered but there was no audio signal from the output jacks or headphones. It is all fixed now.

Jennie plays keys for Kieran Dobson & The State and solo as Nell

This is the prettiest flight case I have ever had in my shop!

 

Trace Elliot 1215 Bass Combo: Oh Dear, Wonky Knobs

Trace Elliot manufacturing, what were you thinking?! Expensive looking collet knobs on splined potentiometer shafts. They didn’t even put little shims in the slots as I have seen some manufacturers do so the slot closes up. The knobs just go on wonky and come loose so you would be paying for this lazy solution when the warranty claims start rolling in.

By the way folks. Don’t ever try to prise the slot apart, the metal breaks so easily and you end up paying for a new potentiometer. The only technique I found to get them to stay on was to give them a really good tighten with a good driver and hope for the best.
