R D Amplification handmade Guitar and Bass amplifiers in the UK


Each commission is priced individually according to specification. Typically the DUALIST head starts at £1350.

Knowing how occasionally 'financially challenged' a lot of musicians are..... we can also agree a stage payment process over the course of the project, with component costs being covered at each stage of the build.

We normally require a deposit up-front in order to cover the costs of buying in the unique project-specific expensive components such as transformers/chassis & other hardware. Deposit typically £350 depending on the size of the project.

Depending on specification and work-load we can normally complete a commission in 12 to 16 weeks.

All amps are hand-wired by Rob using traditional construction techniques and top spec components.


The DUALIST is our core amplifier. Pricing for the DUALIST with various output stages up to 50w is as follows:

DUALIST head Including classic Tube Reverb and tube buffered FX loop starts at £1500.

Combo version £1650 + cost of your choice of speaker (or you can supply your own for fitting).
