The Spaceman Charon Ge/Si Hybrid Fuzz is a fuzz pedal from Spaceman Effects, built and hand-wired in Portland, Oregon. It is a hybrid germanium/silicon fuzz: the circuit combines a NOS germanium transistor with silicon components, including diodes of both elements, and Spaceman describes it as having vintage vibes inspired by classic circuits from the golden age of guitar effects1. Guitar Pedal X identifies the transistor pair as a 1T308B plus a BC50882.
What it does to your sound
Because the circuit mixes germanium and silicon, the Charon covers a wide sweep of fuzz behavior from one set of three knobs. Delicious Audio's Paolo De Gregorio writes that you can "easily traverse from low-gain crunchy overdrive to a menacing aggressive wall of sound, all the way to total signal destruction," with smoky drive, fat saturated distortion and belligerent fuzz along the way1. He credits the careful balancing of the components with producing "a remarkable variety of tones with just three knobs," from subtle crunch to gnarliness up to a wall of sound1.
Guitar Pedal X's Stefan Karlsson, reviewing the Charon in November 2023, called it "beautifully balanced and with a really smart tone stack to get the maximum harmonics out of that" circuit, and described the pedal as warm and harmonic2.
The controls
The Charon keeps things simple: three knobs, in the classic fuzz arrangement2.
| Control | What it does |
|---|---|
| Gain | Regulates the signal level into the circuit. Lower settings are crunchy and smoky with well-defined note attack; medium settings increase compression and bloom; at full it is a rude, belligerent fuzz with accentuated sag and heavy beating intermodulation1 |
| Tone | Reduces bass content as it is turned up, allowing the Charon to remain tight and defined even at high gain settings1 |
| Level | Manages the overall output volume, with plenty of cut and boost on tap1 |
The Gain control's behavior is worth noting for players used to modern high-gain pedals: at its lowest settings the Charon behaves more like a crunchy overdrive, and the compression, bloom and sag build progressively from there1. The Tone knob works as a bass cut rather than a treble boost, which is how the pedal stays tight at maximum gain1.
Placement, switching and build
Delicious Audio gives the Charon's input impedance as moderately low at 100K ohms, making the pedal sensitive to signal-chain placement, and says it performs best placed first in line1. That is a practical point for pedalboard planning: buffers and other pedals ahead of it can change how the fuzz responds.
The Charon's 100K ohm input impedance means it responds best placed first in the signal chain, ahead of buffers and wah or compressor pedals1.
The pedal sits on a cast-aluminum enclosure topped with a durable, engraved vinyl faceplate and a jewel indicator light1. Switching is handled by true-bypass relay switching with a soft-touch footswitch, and the signal path is all analog1. Guitar Pedal X's review describes a gold enclosure with matching gold knobs, "which sounds every bit as good as it looks"2.
Price and availability
Guitar Pedal X's November 2023 review listed the Charon at £199 GBP, and noted that the pedal was not available in the UK at all; Karlsson ordered his from Scott Hager at Axe and You Shall Receive in the US2. The same review's summary line shows the price as $199, so the two figures do not agree within that source2.
How it sits in Spaceman's fuzz range
Spaceman builds several fuzzes around germanium and silicon circuits. The Spaceman Gemini III is a dual fuzz generator, the Spaceman Sputnik III is the company's germanium fuzz, and the Spaceman Rumblefuzz II is a reissue of Spaceman's first pedal. The Charon is the range's dedicated hybrid Ge/Si design, using one of each transistor type in a single three-knob circuit12.

Questions
Is the Spaceman Charon true bypass?
Yes. Delicious Audio's product page describes the Charon as having true-bypass relay switching with a soft-touch footswitch. Relay switching means the bypass path is handled by a relay rather than a conventional mechanical switch, which Spaceman pairs with a soft-touch footswitch on the pedal's cast-aluminum enclosure.
Is the Charon signal path analog?
Yes. Delicious Audio lists the Charon as having an all analog signal path. There is no digital conversion anywhere in the circuit, which matters to players who want the character of the germanium and silicon components to come through untouched.
Where is the Spaceman Charon built?
The Charon is built and hand-wired in Portland, Oregon, according to Delicious Audio's product page. Spaceman Effects builds its pedals in the United States, and the Charon's cast-aluminum enclosure carries an engraved vinyl faceplate and a jewel indicator light.
Where should the Charon go in a pedal chain?
Delicious Audio notes that the Charon's input impedance is moderately low at 100K ohms, making the pedal sensitive to signal-chain placement, and that it performs best placed first in line. In practice that means putting it ahead of buffers and most other pedals, as is typical for fuzzes with lower input impedance.
What transistors does the Spaceman Charon use?
The Charon is a hybrid germanium and silicon fuzz. Delicious Audio describes the circuit as including a NOS germanium transistor, and Guitar Pedal X identifies the transistor pair as a 1T308B plus a BC5088, one germanium and one silicon device working together in the same circuit.
