RD Amplification 8-Ball Custom vintage guitar amplifier



Responding to requests for a single-channel, straight-ahead clean amp, we have produced the Custom 8-BALL. Employing just the ‘Single’ mode circuit from our flag-ship DUALIST Custom amp, we have produced a beautifully voiced singing Reverb amp which is in the best tradition of where guitar tube amps started. Again utilising touch sensitive and dynamic Cathode Biased output stages the Custom 8-Ball mirrors the tonality and response of the DUALIST Custom, just without the overdrive stage and FX loop since it doesn’t need one. Great for players who want a clean musical touch-sensitive amp without the preamp overdrive stage. A really good pedal platform.

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.
