INTRODUCTION

The Procyon Natural Overdrive is a clone of the BJFe Honey Bee Overdrive, a circuit first released in

2002 that is credited for starting the "low gain overdrive" trend.

The circuit itself is a rather unique overdrive design, incorporating both soft and hard clipping and

utilizing frequency-dependent negative feedback from different points in the circuit, for a result that

is often called "amplike" in tone. It is very loosely based on the RAT, and was inspired by the sound of

overdriven Supro amps.

These pedals were handmade in Sweden and were extremely expensive ($300-400 USD), and so in 2011

an agreement was made with BearFoot FX to produce them in the USA for a more reasonable cost.

Bearfoot has also released a number of variants of this basic circuit such as the Model H, Model G,

Honey Beest, Uber Bee, and Sparkling Yellow Overdrive. While each of these circuits are similar, the

Procyon project only supports the standard Honey Bee (both BJFe and BearFoot versions, which have

minor differences).

The updated Procyon V2 has been completely overhauled from the earlier one. Based on our research of

several different Honey Bee traces, we concluded that the original FSB schematic (which all DIY Honey

Bees have been based on for nearly 15 years) was incorrect and does not represent an actual Honey

Bee. You can read more about our conclusions in our article,

USAGE

The Procyon has three knobs and two toggles:

• Drive controls the gain of the op-amp stage which increases the amount of signal clipping.

• Nature is a unique tone control, doing two things at once. On one half of the rotation it affects the

amount of bass in the input stage and changes the gain ratio of the circuit. The other half depends

on the setting of the Mode switch.

• Volume controls the overall output level of the effect.

• Mode (toggle) selects between two different operations for the second half of the Nature control.

Mode I is a source bypass capacitor at Q1, which increases the amount of bass as it's turned up.

Mode II is a variable hi-cut at the end of the circuit.

• Low (toggle) selects between three different bass modes: stock, less bass, and more bass.
