The Martyr pedal is based on the preamp found in the legendary Marshall Valvestate 8100 amplifier from the 1990s.  This amplifier defined an entire genre of music, most famously the sound from Death, Meshuggah, In Flames, Prong, Static-X, and many others.

Amp vs. Pedal! The "Death" Tone (VS8100 vs MARTYR)

Amp vs. Pedal! The "Death" Tone (VS8100 vs MARTYR)

(See below for info, gear used, and links!) I've been wanting to make a comparison video of the Master Effects Martyr pedal, and the Marshall 8100 head, since the Martyr is an "8100 in a box". I've had my 8100 for years and i know it very well, and I'm happy to report that the Martyr pedal really does sound like the 8100! Of course it will never be a perfect 1-1 match, even two 8100 heads won't sound completely identical. These are old amps, and amps can change over time as the components wear out, and some of the new component tolerances have changed over the years. So there are clearly some differences, but they are rather slight in my opinion. Maybe someone else could dial them in more closely, but the sonic signature of the 8100 is very clearly there, and nobody would ever know the difference in a mix! Or especially live, if you want the 8100 sound, but don't want to take your precious amp out of the studio! One thing that is VERY obvious is how quiet the pedal is, compared to the amp. I didn't really realize how noisy it was until I heard them side by side! Get the Master Effects Martyr here: Gear used: For the first part, a Schecter JLX-6 FR, into a Maxon OD808, then into the amp (or pedal.) The second section was a Schecter C7 FR SLS Elite, into a Fortin Grind pedal, then into the amp (or pedal.) For the sections with the pedal, I was using the Marshall's Effects return, to ensure that it was purely the preamp circuit that was being compared. The amp was then hooked up to my home-made 2x12 cabinet, with one T75, and one V30. Both speakers are OLD and very well worn! Each one was mic'd with a single SM57.

As of November 1, 2021 we have refreshed the design of the Martyr.  We listened to all of the feedback from the last 18 months and incorporated them.  The circuit itself remains unchanged.  You still get that classic Valvestate tone but in a smaller 125B enclosure with top-mounted jacks.  We also eliminated the OD1/OD2 toggle switch because... let's face it:  nobody was using OD1.  The new Martyr is all high gain OD2 all the time!


The pedal uses a standard boss-style 9V power supply. There is internal circuitry to generate a ±15V power supply, just like the original amplifiers used.

Controls include: Volume, Contour, Gain, Treble, Middle, and 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

  -  Professional high quality FR4 PCB

  -  Powdercoated enclosure

  -  UV Printed artwork

  -  Top mount jacks

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.

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. 



You will receive a confirmation email with your order information (if you don't see it, check your junk mail for "POWr") and an email from Canada Post with your tracking number when your pedal ships. the tracking information will also be added to the original PayPal transaction.
