IMPORTANT

  • UK CUSTOMERS - Prices exclude VAT (20%) which is only shown in check-out.
  • OVERSEAS CUSTOMERS - UK VAT disappears when you enter your country in check-out. Purchases from outside the UK will NOT pay UK VAT.
  • Instead of flooding you with a huge selection, I have tried to keep shipping options simple and straight-forward.
  • To save you a little money, items under 100.00 GBP are sent without tracking.
  • If you're outside the UK, your purchases may be subject to import duties which I'm afraid, I can't predict.
  • After purchase, you'll want to go to 'Shopping Cart'. Please enter a valid e-mail address and then press <Enter> on your keyboard to bring up shipping options and delivery address entry option. You can still cancel your purchase if you wish.

If you have any questions about my on-line store or the products and services I offer, please take a quick look at my FAQs and of course, you can always just contact me. 🙂


CHANGES TO US IMPORT DUTY

Up until 29th August 2025, items entering the United States with a value of less than $800 were exempt from import duty. The discontinuation of the $800 de minimis exemption for all countries, means that ALL items are now subject to US import duty, irrespective of value. Duty on items from the United Kingdom is 10%.

To ensure that your purchase arrives quickly and without too much hassle, I've chosen to pay the duty via the courier that I use (usually Royal Mail) and as such, I've reluctantly had to split my 'US & Canada' shipping cost into two and increase my charges to the US.

I'm so sorry guys.

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.

SIMMONS SDS7 HEAVEN - Back in eighties, I was part of the Simmons team based in St. Albans, Hertfordshire, England. A couple of years ago, I made the decision to get reengaged with my Simmons past and developed several peripherals for a few of those classic instruments. As it turned out, I designed a lot of bits 'n' pieces for the Simmons SDS7 specifically, so many in fact, that I decided to give the SDS7 its own category in my online store.

Pleiades Lithium Battery Conversion for the Simmons SDS7
Product Details

Pleiades is a 2-in-1 solution offering easy Ni-Cd to lithium battery and with the addition of a Tubbutec uniPulse, MIDI conversion of your Simmons SDS7.

Unlike Ni-Cd batteries, lithium batteries don't need regular recharging. A 3.6V AA LiSOCI2 battery will theoretically last for 150 years!

The voltage that's actually going to your SDS7's SRAM chips can easily be monitored by simply removing the SDS7 front panel and hooking up your digital multi meter to a pair of conveniently located terminals on Pleiades.

When the battery on your Pleiades will eventually need changing, a second battery holder allows you to drop in the new battery before removing the old one so you won't be putting your SDS7's memory at risk.

Always wanted a MIDI Simmons SDS7? Well now Pleiades also makes the installation of the Tubbutec uniPulse MIDI to trigger adapter into the Simmons SDS7, a breeze.

As with all my products, Pleiades doesn't require any holes to be drilled or any other drastic modifications to be made to your vintage equipment. Pleiades occupies a spare voice module slot (preferably slot 12) in your SDS7. The corresponding pad trigger input which is then redundant, is used for MIDI IN. If you every want to return your Simmons SDS7 back to factory, don't worry, it's easy.

Pleiades is fully compatible with my Dark Matter replacement power supply for the Simmons SDS7. Pleiades can be used in place of Dark Matter's battery-board, just by swapping one connection.

IMPORTANT: Tubbutec uniPulse is NOT included with Pleiades. Please purchase Tubbutec products here.

When ordering uniPulse from the Tubbutec website, ensure you request the uniPulse Pleiades kit comprising the following items:

  • 1 x uniPulse PCB.
  • 26-way IDC cable with IDC housings at both ends (approx. 30cm).
  • 1 x MIDI header with red and black wires with no 5-way DIN socket (approx. 70 cm).
  • SDSV / SDS7 firmware.

As of 7th May 2025, RESET-7 POR (Power-on-Reset) upgrade for the Simmons SDS7 can be purchased at a discount price when buying Pleiades.

RESET-7 is a power-on-reset upgrade which has the effect of extending the life of your new battery by replacing the original POR chip with a newer device that has a minimum operating voltage which is the same as the minimum memory retention voltage of the 6116 memory chips. You can read more about RESET-7 here.

I'm ex-Simmons and Pleiades is not just made locally here in the United Kingdom, it's made a few miles away from the old Simmons factory where I used to work, in St. Albans, Hertfordshire.

Pleiades is NOT supplied with a battery. For best results, I recommend 1 x SAFT 14500 or EEMB ER14505

Li-SOCI2 battery.
