PRODUCTS - With over forty years of electronic design and manufacturing experience, mostly in the audio industry, I still love taking on challenges and winning! For me, designing something and seeing it through to a commercial product, is as creative as writing and producing in the studio. Under PRODUCTS, you can browse through the things I make to help musicians, producers and engineers, along the way. 🙂

I also repair and  service studio and live performance gear as well as renovate vintage synthesisers, signal processors and guitar amps.

SERVICES (Creative) - I've been involved with studio and live music production, since 1985. It's my passion and I have a huge wealth of knowledge and experience.

Vecoven Original PWM kit for Roland Super-JX

In stock
Product Details


I can install Fred Vecoven's original PWM kit into your Roland Super-JX. The installation includes socketed ICs, all additional Molex connectors, ribbon cable and hardware.

Fitting Fred's PWM kit is so much easier with my V02 bracket but you'll need Guy Wilkinson's P0004 power supply to take advantage of the V02.

If you want to keep your original Roland power supply, Fred's PWM kit will have to be mounted to the voice-boards. This requires drilling holes, into the MKS-70 voice-boards. Hence, this is the more expensive option.

This service includes me supplying Fred's PWM kit. If you have already bought a PWM kit or simply wish to buy it yourself anyway, please contact me, should you wish me to install it for you.

Read more about Fred's original PWM upgrade kit for the Roland Super-JX here.

Pricing for supply and installation of Fred's latest digital PWM kit will be coming soon.
