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.

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.

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.

Installation of 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.

Here’s a summary of what Nebula offers:

  • Plug and play installation with no soldering required
  • 6dB hotter signals than unbalanced outputs
  • Increased immunity to external noise
  • Better signal-to-noise ratio
  • Greater dynamic range
  • Reduced crosstalk between left and right channels
  • Reduced crosstalk between module-boards
  • Powerful and cleaner headphone sound
  • Increased MIDI stability

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

The output mode of Nebula is therefore switched via a slide switch which sits in the position of the original output level selector switch.

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 a rather cool looking reference label which has self-adhesive backing which is finished in matt.

UPDATE - 19th January 2024

Nebula's balanced outputs provide increased immunity your MKS-70 and the destination device such as mixer. Nebula can't 'filter' noise that's been picked up inside your MKS-70. Any noise present at Nebula's inputs will be passed on to it's outputs.

My screened audio cables for the Roland MKS-70 help to reduce the pick-up of noise from within the box. These are now available at a discounted price when you buy Nebula.
