This pedal was part of a special offering for those that attended Reverb’s 2023 Chicago Boutique Effect Pedal Showcase, hosted at Chicago Music Exchange. Remaining inventory is now available.

The Cestus started life as a simple clean boost pedal but was discontinued some time ago. When we reworked the SusMaryOsep! for RJ Ronquillo the first thing he requested was a Treble Booster. After that circuit was completed we knew we had to re-release the Cestus as that treble booster! 

This new version of the Cestus uses a silicon Mil Spec NOS 2N2222A transistor in lieu of a germanium transistor. This gives us the consistency and inventory necessary to produce these. In switching to silicon you have a Treble Boost that’s got a unique grit and hair to it that works well even on slightly cleaner guitar amps. 

Switch on the face of the Cestus is a 3-Way voice toggle that goes from classic/thin boost tones in the middle, more mid-foward tones in the up position, and bass heavy and thick tones when switched downward. This handy toggle allows you to match the voicing with your setup or allows you to cover a wider range of tones. With the right amp or dirt pedal after this unit you will be able to run the gamut of lead and rhythm tones of yesteryear. 

The SET control sets your overall output and the wide range of output lets you go from just a slight re-voicing of your signal to amp crushing power when dimed. The artwork is inspired by the original amp top boxes that inspired this unit.

Nice shoes!
Size: 11, Color: Black Full Grain
I bought them in black and I like them so much I will be buying the brown soon. They fit true to size and are comfortable and stylish. I like the clean simplicity. They're basically a dressy sneaker which is perfect for my job's 'dress code'. Yet they're stylish enough to be worn weekends or a night out. They seemed just a touch stiff out of the box but IMO that's completely normal and fine - after just a couple days of wearing them they are breaking in nicely. No complaints on that. They seem to be of very high quality and I'm very happy with them.
