Electro-Harmonix spins out a budget take on the Interfax HP-1 Harmonic Percolator - the EHX Percolator - with 2 extra controls
Key Points
Electro‑Harmonix Percolator: a budget take on the Interfax HP‑1 Harmonic Percolator. U.S. price $99. As of 2026-07-13, the price was £99 (presumably).
Adds two extra controls: a further Bias to adjust output profile/texture, and a Gain‑Range Drive/Fuzz toggle. Controls listed: Balance (Volume); Harmonics (Gain/Fuzz); Bias (Character/Texture); Gain Range: Drive/Fuzz.
Artwork uses faux printed‑on Dymo style labels designed to look out of alignment; it sets off OCD. Should be widely available in the USA already. Demos: Fuzz — Harmonic Percolator. The writer will likely pick one up in July.
I’m not sure we need yet another Percolator out there, we have plenty of options already. While the price here is undoubtedly highly attractive - which cannot be said of its artwork! Not only does it have faux printed-on Dymo style labels, but they’re designed to look all out of alignment - to indicate that those labels were applied by a low-skilled employee. This is overall a familiar trope, but the higgledy-piggledy nature of that arrangement really sets off my OCD!
I have several great examples of the Harmonic Percolator - and despite my misgivings about the artwork of the EHX Percolator - I will still probably spring for one - the price is entirely conducive towards that!
We essentially have a further Bias control - to better adjust the output profile, and we have a Drive / Fuzz toggle-switch which is presumably Gain Range / Structure.
Controls - Balance (Volume), Harmonics (Gain / Fuzz), Bias (Character / Texture), Gain Range : Drive / Fuzz.
Apart from the throw-away artwork, there is much to like here.
These should be widely available already in the USA - for just $99, and presumably £99 and equivalent this side of the pond in a few weeks. I’ve complained about it before - but EHX and MXR pedals always seem to take too long to reach the heart of civilisation!
I will likely pick one up sometime during the month of July!
