Dazatronyx Big Fuzz Console

The Dazatronyx Big Fuzz Console is a fuzz pedal that takes the classic four-stage Big Muff circuit and unrolls it onto the front panel. Where a normal Big Muff clone fixes its component values inside the box, the Console puts external switches and sockets on nearly every value, so a player can change capacitors, resistors and transistors on the fly¹. RockBoard's PedalPedia describes it as an advanced, breadboard-style development tool and multi-fuzz pedal designed for ultimate Big Muff tone-shaping¹.

It is fully analog, hand-built in Melbourne by Darron Thornbury of Dazatronyx, and listed at $499 direct from the Dazatronyx webstore as of February 2026²³. Delicious Audio calls it "a deeply thoughtful, fully analog development tool that invites you to look under the hood of why classic fuzz circuits behave the way they do"².

A Big Muff circuit with nearly every value switchable

A Big Muff's character comes from the specific capacitor and resistor values in its four gain stages, which is why Triangle, Ram's Head and Russian versions of the same circuit sound different. The Console's approach is to make those values player-selectable: each gain stage has a 3-way toggle for choosing different capacitor and resistor values, and sockets allow transistors to be swapped¹. Delicious Audio notes that with this you can "map out vintage specs like Triangle, Ram's Head, or Russian units, or venture entirely off-map into custom territory"².

The controls, stage by stage

The Console follows the four-stage Muff architecture, with each stage given its own set of controls¹:

Guitar Pedal X's Stefan Karlsson documented how this works in practice. In his Violet Ram's Head session he set values like the tone stage high-pass filter capacitor (3n3, against a reference of 560 or 470p), a stage 3 high-pass filter at 47n, and a stage 4 low-pass filter at 470n, each chosen against reference values he aggregated from resources including Kit Rae's Big Muff Pi page⁴. His reference settings for that voicing also put the volume control at maximum⁴.

Transistors and clipping diodes

Each of the four gain stages carries a 6-way rotary transistor selector with these options³:

• 2N2222A (socketed)
• BC337-25
• BC547B
• BC547C
• 2N5088
• 2N5089

The 2N2222A position uses a socket, so a player can insert other transistors directly³. On the fixed-transistor positions, the Ultimate Multi-Muff's selectors offer BC337-25, BC547B, BC547C, 2N5088 and 2N5089⁴.

For clipping, the circuit uses 1N914/1N4148 small signal silicon diodes, with no other diode options. Guitar Pedal X reports that most circuit versions can be recommended to be built with these, and that the line had to be drawn somewhere on options³. The clipping stages do include a no-clip option on their selectable capacitors, which lets a stage run without diode clipping².

Reproducing vintage Big Muffs

The Console's main draw for many players will be its ability to chase specific Big Muff voicings. Because nearly every component value can be manipulated on the fly through external switches and sockets¹, a player can dial a circuit toward a particular vintage character rather than being locked to one fixed build. The reference values behind those settings were aggregated from a variety of resources, including Kit Rae's Big Muff Pi page⁴, and the transistor options selectable on the rotary controllers include BC337-25, BC547B, BC547C, 2N5088, and 2N5089⁴.

Of the Violet Ram's Head mapping, he wrote:

He settled on BC337-25 or BC547C transistors for the Green Russian voicing, with a detailed resistor and capacitor profile across the stages⁴. Concluding the series, he wrote that the Console "consistently delivers my favourite Big Muff tones, this is for sure the Ultimate Big Muff Pedal, and one of the very best multi-fuzzes overall"⁵.
