Hi, I’m Rowan, Owner and Engineer at Keld Ampworks (www.ampworks.co.uk), a busy guitar amplifier repair service serving customers from Newark, Nottinghamshire, UK.

RSD Sound is a means of making hard to find repair parts more widely available to other repairers and hobbyists. I only sell parts on here that I have actually used in my repair work.

This website also makes available my various upgrade PCBs that address design flaws in amps such as the Hot Rod Deluxe and the Blues Junior and makes them much much more reliable.

You’ll also find some gadgets for Roland GK synths.

Because I’m a one man show, shipping times can sometimes be delayed.
