The Thespian Valve preamp is a recreation of the Fender Dual Showman/Alembic F-2B preamp made famous by David Gilmour of Pink Floyd.


New for 2023!  The Thespian Valve Preamp... reworked!  We had major supply issues with parts for the original version so we took the opportunity to re-vamp it.   Smaller enclosure, optimized the power supply, moved the furniture around, added some windows and new paint, and voila!

The pedal uses a standard boss-style 9V/500mA power supply and uses an internal SMPS to boost this up to 200V for the 12AU7 tube.

Controls include: Volume, Treble, Middle, and Bass with a Bright switch and a Mid Boost switch. 


Each pedal uses a professionally assembled PCB and is proudly assembled by hand in Calgary, Alberta, Canada.

Other features include:

  -  True bypass

  -  Internally mounted 12AU7 tube

  -  Professional high quality FR4 PCB

  -  Powdercoated enclosure

  -  UV Printed artwork

The end result is high quality pedals that sound amazing, are consistent from pedal-to-pedal.

Each pedal comes with a 1 year warranty on parts and labour. Note that the warranty does not cover damage due to using an improper power supply or other misuse. 

The price is $349US + shipping.

Shipping within Canada and the US is $20US.  Shipping to the UK, Western Europe, Australia, and Japan is $60US.  For other regions, please inquire for shipping rates.

For US customers, note that you do not have to pay any import duties or tariffs.

For customers outside of North America, please note that you will be responsible for any customs/import/VAT charges that your country levies on the pedal. 

Thank you and stay safe!
