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 this category,  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 while I 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.

MARSHALL JMP-1 STUFF - Putting all my bits 'n' pieces for the Marshall JMP-1 into one place will hopefully make things a little easier for fans of this legendary MIDI valve pre-amp.

Product Details

Two type of replacement knobs, nut and bezel sets available for the front panel of the Marshall JMP-1.

The 'Performance' set has knobs which are very similar to the original JMP-1 knobs. Both are 6mm spline shaft types but one has been modified so as to fit the 1/4-inch D shaft on the encoder. The socket bezels are integrated into the moulding of the socket nuts.

A little more stylish, the 'studio' set comprise one 6mm spline shaft fitting knob for the volume pot and a 1/4-inch D-shaft fitting knob for the data encoder. The other difference is that the bezels / nuts for the sockets are 2-piece. This kit is allows for a simple and cool customisation of your Marshall JMP-1.

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.


A WORD ON SHIPPING COSTS

Annoyingly, my shopping cart software displays shipping information after you’ve confirmed your payment option. I’m trying to get this changed as I believe that customers should always know exactly what they’re paying. Of course, I have no control over import duties but I try my best to give clear, concise information.

I therefore maintain a ‘Shipping Prices’ page and visitors to my website who are interested in buying stuff, have the opportunity to check shipping costs to their country / region.

My shipping costs are calculated on item value and not weight as everything is insured.
