McCaffrey Audio Reactor Boost Compressor


One very cold Wisconsin winter Ryan McCaffrey was suddenly bombarded with demands for compressor builds. Having never been a big fan of compressors he set out on a journey finding the “perfect” compressor. He found out a couple of key things with the many great, okay and just bad compressors. First being, that they either favored single coils or humbuckers but never both and the second being, most had just too much squish. He wanted a compressor that played nice with all guitars regardless of race, creed or color. In the end the Reactor was born. This pedal borders on illegal in many states because it just aint right, but man is it cool.

Compression? YES! Boost?? YES! Enhancement of your overall tone? You best believe! This is a unique pedal that rides the line on three different pedal concepts.

** This is not your typical OTA style comp that you roll out for Nashville style squash.  It is more of a tone enhancer really.


Neutrik Jacks

Power: Negative center 2.1mm standard 9V power supply.

Single dual op-amp effect with J-Fets and a single diode towards the end of the circuit.

Level: Increases/decreases output volume of pedal. Increase the level and notice how the pedal starts to push the front end of your amp and other pedals.

Fusion: Affects the amount of compression and drive when the level is increased.

Critical Mass Switch: Three-way switch that adds bass response to the effect. Middle is the stock or “jangle” position. Adds a bit O’ snap to pick’n. Left adds just a bit more bass response. Right adds the most bass response.

Mad Dog’s Favorite Setting: Put this in front of your slightly driven amp and enjoy with a fine cigar!

Level to 5:00 or the max setting.
