Click on the Guitar & Bass logo to read a review of the Plexi 18

The Plexi 18 is a stunning recreation of the classic 18w 'Baby-Bluesbreaker' amplifiers introduced by Marshall in the 1960's.
Completely handwired using the highest quality components, these amplifiers deliver spades of classic British crunch tones.

Available in three versions, either TMB, Tremolo, or Reverb in both Head and Combo format.

TMB: Two channels, Hi/Lo inputs, one Volume + Tone, the other Volume, Treble, Middle, Bass.

Tremolo: Two channels, both with Volume and Tone controls, Hi/Lo inputs, Speed and Intensity controls for the tremolo effect.

Reverb: Single channel, Hi/Lo inputs, Preamp, Master, Reverb, Treble, Middle, Bass, Presence.

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.
