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. 🙂

SERVICES (Technical) - Don't let the fact that you're unable to install one of my systems into your beloved piece of vintage equipment scare you off! I'm more than happy to do that for you. 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. Being a musician myself, I'm able to connect with my clients and make magic things happen. I'm also a keen photographer, website and graphics designer. If you think I can be of assistance, please do check out this category.

UPCYCLED AUDIO - My project for 2023, Upcycled Audio offers quality equipment vintage equipment that's been renovated and / or upgraded for a modern world. You can read more about it here.

In stock
Product Details

UPDATE - 17th October 2021

Since launching my replacement knob and bezel sets for the Marshall JMP-1, I've had a lot of inquiries for the power switch button (or cap). Unfortunately this item seems to be quite obsolete and I just haven't been able to track down a direct alternative.

I have however, found an alternative which although not identical, does seem to do the job. This is now included as standard in both my Performance and Studio knob and bezel kits for the Marshall JMP-1.
