TETRAGON
The Tetragon is based on the preamp found in the legendary Mesa/Boogie Mark IV amplifier.


The pedal uses a standard boss-style 9V power supply. There is internal circuitry to generate an 18V power supply for more headroom and amp-like dynamics. Note that this pedal is intended to be used in front of a guitar amplifier and that using it direct into a power amp or FX loop return may not yield intended results.
Controls include: Volume, Drive, Master, Bass, Middle, and Treble. There are three toggle switches for mid boost, bright, and fat (bass).
Each pedal uses a professionally assembled PCB and is proudly assembled by hand in Calgary, Alberta, Canada.
Other features include:
- Soft-touch relay true bypass for improved reliability
- Alpha 16mm potentiometers
- Lumberg power connector
- Neutrik jacks
- Professional high quality FR4 PCB
- Powdercoated enclosure and 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 $199US + shipping.
Shipping within Canada and the US is $20US. Shipping to the UK, Western Europe, Australia, and Japan is approximately $60US. For other regions, please inquire for shipping rates.
For US customers, you will not have to pay any import duties or tariffs. USPS will delivery the pedal to you once it passes through customs.
