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 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 vintage equipment that's been renovated and / or upgraded with a view to deliver classic quality performance with modern convenience. You can read more about it here.

Nebula balanced outputs for the Roland MKS-70

In stock
Product Details

Nebula is a replacement jack-board for the Roland MKS-70 which offers uprated MIDI hardware and balanced outputs. You can read details here.

Unlike the original jack-board which implements a rather ingenious switching logic via the output sockets, Nebula requires that the output mode be changed manually from stereo to individual. That's because switching 3-pole sockets are wide and simply wouldn't have fitted.


Nebula OS (original switch) does not come with a switch to change the output configuration from stereo to individual and requires that you transfer the output level selector switch from your original jack-board to Nebula's jack-board. From the outside, your MKS-70 will look no different.

Nebula DS (DIP switch) is plug 'n' play with a small DIP switch accessible via the original output level selector switch slot.

Both Nebula OS and Nebula DS cost the same but please make sure that you select the version that you want.

Like all my stuff, Nebula is hand-made by me in the UK. Please also note that I do NOT believe in spending loads of money on fancy looking packaging. Please don't be disappointed if your Nebula arrives in a rather boring looking box!

And finally, Nebula is supplied with one of two rather cool looking reference labels which have self-adhesive backing and which are laminated with a matt finish.

Hand-built in Hemel Hempstead, United Kingdom.


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.
