The Mad Professor Milestone is a germanium fuzz pedal from Mad Professor, part of the company's handwired series made in Finland1. It was announced in September 2026 and offered for preorder, with pedals shipping from 5 October 20262. What sets it apart from most fuzz pedals is an onboard transformer circuit that lets it sit anywhere on a pedalboard, including after buffered pedals, where traditional germanium fuzzes usually misbehave3.
A germanium fuzz with an onboard transformer
Mad Professor describes the Milestone as a fuzz "inspired by vintage mixing consoles, reimagining the earliest fuzz sounds for the modern player"1. It is built around authentic germanium transistors, and Guitar Pedal X's photos of the handwired interior show two TO-5 type metal can germanium transistors, which the site suggests could be 2Nx or ACYx variants, though the maker has not identified them2.
The headline feature is the onboard transformer, which works as a kind of pickup simulator. Delicious Audio explains what it does for a player23:
"Onboard Transformer Circuit: Solves traditional germanium impedance issues, letting you place the fuzz anywhere in your [chain]"3
This is the practical point of the pedal. Germanium fuzzes are famously fussy about where they sit: put one after a buffer or another pedal and the low impedance driving it changes the character, often thinning or dulling the fuzz. The Milestone's transformer isolates the fuzz stage so it "can sit happily after buffers or other pedals"3. Guitar Pedal X makes the same point, noting the transformer "means that it can be placed more liberally" on a board2.
Premier Guitar describes the circuit as dynamic and touch sensitive, and designed to stack well with other effects1. Delicious Audio adds that it "cleans up remarkably well with your guitar's volume knob and reacts instantly to your pick attack"3, the volume-knob cleanup that germanium circuits are known for.
Bass and Treble controls
The Milestone carries four controls: Volume, Fuzz, Bass and Treble2. The two-band EQ is the shaping tool, and it is there for a practical reason.
| Control | What it does |
|---|---|
| Volume | Sets the output level |
| Fuzz | Sets the amount of fuzz |
| Bass | Shapes the low end of the two-band EQ |
| Treble | Shapes the high end of the two-band EQ |
Delicious Audio says the dedicated Bass and Treble controls offer "enough frequency-shaping flexibility to adapt the fuzz" to different amplifiers, guitars, or even bass guitar3. Premier Guitar calls the two-band EQ a way of fine tuning your guitar tone1. For a player, that means the fuzz can be dialed darker or brighter to match a bright combo or a dark amp, rather than living with a fixed voicing.
Where it comes from and what it costs
The Milestone is part of Mad Professor's handwired series, handmade in Finland1. Delicious Audio calls it a premium handwired build, meticulously built in Finland3. Mad Professor also makes the FUZZ32, which sits outside the handwired line.
On price, the sources differ slightly. Premier Guitar gives the Milestone a street price of $3701, while Guitar Pedal X listed the preorder price as €330 / $378 / £2832. Both figures are given here as stated; the difference is small but real.
The Milestone has no battery compartment and runs on 9-volt external power only1, so it needs a spot on a powered pedalboard or a dedicated 9-volt supply.

Questions
Does the Mad Professor Milestone take a battery?
No. The Milestone runs on 9-volt operation from an external power supply and has no battery compartment, so you will need a pedalboard power supply or a standalone 9V adapter to run it.
Is the Mad Professor Milestone true bypass?
Yes. Premier Guitar lists true-bypass switching among the pedal's features, so with the effect off your signal passes through without active circuitry in the path.
Can the Milestone go after a buffered pedal?
Yes. Its onboard transformer circuit isolates the germanium fuzz stage and solves the traditional impedance issues that make most germanium fuzzes misbehave after buffers, so it can be placed more liberally on a board.
Where is the Mad Professor Milestone made?
It is handmade in Finland, as part of Mad Professor's handwired series of premium pedals built there.
Is the Milestone a germanium or silicon fuzz?
It is a germanium fuzz. It is built around authentic germanium transistors, with Guitar Pedal X spotting two TO-5 type metal can germanium transistors inside the handwired build.
How much does the Mad Professor Milestone cost?
Premier Guitar gives it a street price of $370, while Guitar Pedal X listed the preorder price as $378, also quoted as €330 or £283.
