After adding the PB16 to my lineup, the next step was to do a Tweed version - The PT20

Unlike the Brown and Blackface models, I've designed this amplifier to run a pair of cathode-biased 6L6 power valves. This gives the amp a bold, powerful tone with just a modest increase in volume. The preamp section is based on the classic Tweed circuits of the 50's.

I use very high quality components, sourced from UK companies if possible.

I do make a few small modifications to the original design, mainly an improved grounding scheme along with a few tweaks to make it more durable/reliable.

I stand behind every amplifier I make. Every Rift amplifier is guaranteed against defects in craftsmanship and components (excluding certain items) for the life of the amplifier (or my life, which ever ends first) as long as it remains in possession of the original owner.

Second hand amplifiers are not supported by the warranty.

Any user modifications or external modifications even by a qualified technician,
abuse and damage beyond normal wear and tear will void this warranty.
