Audio Cultivation Projects' Fourth Solid-State Distortion is a great take on those trashier sounding solid state amps - using a Hybrid Transistor + OpAmp topology

I’ve been wanting to cover this pedal since I first glimpsed it. Something about its elegant design really appeals to me - as does its Drive / Distortion output profile. It supposedly sits somewhat adjacent to the Music Man 112 RD, Epiphone Studio 10s, and the Silvertone 1464 solid state amps - for that kind of brasher garage-punk / rock sound. 

It starts with a fairly conventional control topology of Output / Level, Gain and Shape (Bass EQ), 

while it’s 3 toggle switches make it really unique :

CHOKE - toggle-switch creates a short in the circuit which accentuates the trashy decay. In the middle, it is wide open, flipped up it is the most choked out, allowing for some low biased, gated sounds. Flipped down it is somewhere in-between, slightly gated, with a buzzy decay.

DEEP - toggle-switch adjusts which bass frequencies are amplified in the first gain stage, middle for the least, flipped down for the most, and up for in-between.

DARK - toggle-switch adjusts the treble response of the Fourth, middle for the brightest, flipped down for the darkest, and up for in-between.

This is a really cool looking / sounding pedal which deserves some support.

Available for orders right now on the Audio Cultivation Project’s Webstore - where it goes for $229.
