The Emma Electronic ReezaFRATzitz is a distortion pedal from Denmark's Emma Electronics, a company whose product page calls it "your golden ticket to distortion dreamland" and promises "a plethora of roaring amp-like distortion tones on tap"1. Its defining feature is a Bias control that shifts the pedal's distortion character between two amplifier classes, Class B and Class A, and anywhere in between12.
The Bias control: Class B to Class A
The Bias knob is the heart of the pedal. Emma's own page describes it as the pedal's magic: it "lets you alter the harmonic content and attack response of the pedal from that of a Class-A to a Class-B amp and anywhere in between"1. Delicious Audio's 2012 review puts it in practical terms: fully counterclockwise gives Class B distortion, fully clockwise emulates Class A distortion, and the middle positions blend the two sounds2.
At the Class B end, Emma describes an amp class that is rarely used but known for its flab. The reviewer found that sound deep and compressed, along the lines of a cranked Marshall JCM900 head2.
What it sounds like
Delicious Audio's reviewer, writing in April 2012, described a pedal that is not subtle: "It goes from distorted to very distorted, screaming like a trapped witch at the slightest opportunity."2 The same review noted limits in tonal range but came down firmly positive on the pedal's character:
"Despite these limitations, though, this pedal is a blast to play though, and it's easy to unleash your squealing inner rock god."
For players comparing distortion options, the Bias control sets the Reezafratzitz apart from pedals with a fixed clipping character: it sits among the wider field of distortion pedals, with overdrive-adjacent territory covered on the overdrive pedals page123.
The ReezaFRATzitz 2
Emma Electronic later released the ReezaFRATzitz 2, an overdrive and distortion pedal designed to emulate a cranked amp as faithfully as possible. The maker says it is "based on the best sounding ReezaFRATzitz 1 we could find," with added low and high frequency controls, and it carries the same Bias control that adjusts the pedal's inner workings from Class B at far left to Class A at far right3.
As of 26 October 2026, the ReezaFRATzitz 2 was listed as sold out on Godlyke Distributing's page, with pre-orders open for early November shipment3. Its listed regular price is £138.00 GBP3.

Questions
What does the Bias knob do on the Emma Reezafratzitz?
The Bias knob adjusts the harmonic content and attack response of the pedal, moving it from Class B distortion at one end to Class A distortion at the other. Fully counterclockwise gives Class B distortion, fully clockwise emulates Class A distortion, and anywhere in between blends the two sounds.
What is Class B distortion in a guitar pedal?
Class B is an amp class that Emma describes as rarely used but known for its flab. On the Reezafratzitz, with the Bias knob fully counterclockwise, Delicious Audio's reviewer found the Class B sound deep and compressed, along the lines of a cranked Marshall JCM900 head.
How much does the Emma Reezafratzitz cost?
When Delicious Audio reviewed the original Reezafratzitz in April 2012, it carried a street price of $245. The later ReezaFRATzitz 2 is listed by Godlyke Distributing at a regular price of £138.00 GBP.
Is there a ReezaFRATzitz 2?
Yes. Emma Electronic makes a ReezaFRATzitz 2, an overdrive and distortion pedal based on what the maker calls the best sounding ReezaFRATzitz 1 it could find, with added low and high frequency controls and the same Bias control. As of late October 2026 it was listed as sold out, with pre-orders open for early November shipment.
