Mojo Hand FX Unleashes the Klon-Style Sericon
December 6, 2021 · 5 sources

Mojo Hand FX announced the Sericon, a Klon-style overdrive pedal with three gain stages and a low-pass filter, built in a limited run and set to be discontinued once its parts and enclosures run out1. The pedal is made in the USA, carries a lifetime warranty, and ships as an individually serial-number plated limited production issue with true bypass21.
The Sericon's circuit is identical to the ProAnalog Devices Manticore V2, a circuit Delicious Audio described as very well regarded, with the project finished under the Mojo Hand FX brand1. Delicious Audio called the result "a highly tweakable and interactive version of a 'professional' gold overdrive"1. The name comes from an alchemical term for "a solution of unknown composition," as Guitar World reported3. Visually, the pedal keeps things spare: MusicRadar noted "just five red dials on a silver painted enclosure"4.
"This Klon-style overdrive has three gain stages, plus a handy low-pass filter for added flexibility."
Inside, the signal is split into two op-amp stages with separate Gain and Drive controls, which then meet at a third gain stage1. The five controls each shape a different part of that chain:
- Drive sets the level of the first gain stage, which in turn affects the harmonic complexity of the later stages5
- Gain adjusts the gain of the second stage1
- Blaze is the final adjustable gain stage, built around a low-pass filter; at lower Gain and Drive settings it brings in low-end warmth, while turning it counterclockwise tightens the low end and turning it clockwise adds beef and thick saturation1
- Treble is a post-distortion control of the high frequencies1
Gearnews found the pedal offered more than the usual Klone fare, writing: "Overall, it is a nice take on a Klon-style circuit, and not just your average Klone trying to replicate the original," with the low-pass filter potentially adding more girth to the overall sound and design5.
Power comes from a standard center negative 9V DC supply, which is not included, and there is no battery provision14. The enclosure measures 4.7" L x 3.69" W x 1.37" H1.
The Sericon is a limited production issue. Mojo Hand FX stated the pedal will be discontinued when the present parts and enclosures are exhausted1.
