Caleidoscopia

Project overview

Inspired by Catalinbread Pareidolia. Caleidoscopia is a pedal emulation of the Tremolo from the 60s Brownface Amps.

Introduction

Caleidoscopia should be described as a mix between vibe, phaser, and tremolo. The result is a complex and subtle sound. That’s probably why the original 60th pedal has “harmonic mesmerizer” as a subtitle under the name. It adds a unique color with quite some highs to your tone, even if you set everything at 0% and boost the volume (yes, you can use it as a volume boost). Don’t let the fact that it only has rate, depth, and volume deceive you: this little treasure also delivers an extensive range of sounds.

Regarding the technical aspects, there are plenty of fake chips from the XR2206cp out there; We highly recommend using a trusted source for this and spend a few bucks extra than going through the hustle of troubleshooting later. Its ability to boost lets you add a volume pot up to a500k, but it gets harder to dial in the unity level. So, we suggest reducing this value to a250k or even a100k depending on your taste if you’re not interested in this little extra feature.

Try the Caleidoscopia into the front of any clean amplifier’s effects loop to give your sound some sick 60’s swirl.

Many struggles to classify the effect this little gem of a pedal offers; all we can say is that the result is unique and beautiful.
