The Spaceman Effects Aphelion Harmonic Overdrive is a harmonic overdrive pedal from Spaceman Effects, the hand-built pedal maker. The maker's own product page calls it "the latest Spaceman tone machine," and at the time of verification that page lists the pedal as sold out1. It sits in the overdrive family, alongside other drives in the Spaceman range such as the Apollo VII and the Polaris.
What it does
The Aphelion is a harmonic overdrive, a drive design aimed at shaping the harmonic content of the signal rather than simply clipping it harder. Premier Guitar's review described how the pedal "uses three very familiar parameters for shaping and producing its spacious textures," pointing to a conventional control layout applied to a less conventional drive circuit2. For a player, that means the Aphelion behaves like a standard three-knob overdrive on the surface, while producing what the reviewer characterized as spacious textures.
Background
The pedal was featured on Pedal of the Day on Monday, July 28, 2014, which introduced it as "the Aphelion Harmonic Overdrive guitar effects pedal from Spaceman Effects"3. That places it among the earlier drives in the Spaceman lineup, well before the company's later releases such as the Apollo VIIb Voyager and the Cadet Series versions of the Polaris.
The maker's product page lists the Aphelion as sold out1.
