About us

We are a small group of guitarists who happen to also be electrical engineers, an amp technician and programmer located in the Midlands UK, dedicated to quality workmanship and take huge pride in our work and customer service - currently we operate not for huge profit, but to establish our name and reputation.

Hopefully our prices reflect this, they only just cover our materials, import costs, equipment, chemicals & fuel to the post office. Every single surplus penny earned gets ploughed into the purchase of equipment and test pedals/pickups/leads for us to develop new mods on. However our customers are quick to point out that the quality of our work is second to none! Many mods are fine tuned with the help of professional musicians to meet their needs, and ensure they sound great at stage performance volumes.

Because we want the Holy Grail of tone also!


Our research and development guys have been busy beavering away in one dark corner of our workshop for the past couple of months developing a true bypass system that can be dropped into most Ibanez/Dunlop and some Boss pedals (others manufacturers & models still to be determined). Finally the fumes have cleared and the end result is a small circuit approx 35mm x 25mm, that requires very little power to operate, that will actuate true bypass and LED indicator via a miniature relay.
