Discover the iconic RD Amplification tone with our handcrafted custom guitar amplifiers. Each amplifier is meticulously crafted and delivers unrivalled tone and quality.


The concept behind the DUALIST Custom was to provide something just a little bit different whilst embracing the best of a great tradition of classic guitar amplification.


To facilitate the more extreme Heavy Metal and Hard Rock players we have taken our classic DUALIST Custom dual-gain preamp circuit and re-worked it into a hardwired none-switching single-channel version destined to melt your face!


The '8-Ball Custom Reverb' is a straight ahead reverb amp based on the 'Single' mode of our classic DUALIST circuit. Essentially pitched as a straight ahead 'clean' amp for those players who do not require the overdrive from the preamp.

BASS 100

A pure all-valve circuit with some suitable component tweaks for bass EQ in the preamp, and typically employing an output stage utilising either pairs of KT88, 6550 or quad 6L6.

“So overall - wow!”

I thought it would be good, but have to say mate, you've exceeded my expectations. A really, really fabulous amp ...! Thanks again - it's already a joy, and that's before I've really got to know it and live with it. Superb stuff.

My new Dualist is an amazing sound machine - Rob has the nack no doubt about it - played my second gig with it this weekend (after he tweeked the tone for me), and I can not imagine playing without it now - what a sound, from shimmering glassy crunch, to balls out overdriven valves - This is an amazing amp - if you want a great sound, get one.
