Ac noises Urla CMOS Fuzz + Dual Resonant Filter

AC NOISES Urla CMOS Fuzz + Dual Resonant Filter is a loud, aggressive and experimental compact pedal which consists in 2 effects in 1 device.

A CMOS chip works with digital logic (1, 0).
Compared to the transistor based fuzz circuits (both germanium or silicon), in a CMOS fuzz there is no "in-between", no "dynamic range", no "vintage tone" or anything like that. There are just 1s and 0s, so no matter which kind of waveshape you put into it: the output will always be square wave with no adjustable gain neither since the square wave is as distorted as it can get.
The URLA obviously makes no exceptions and it provides an overdriven, brutal, glitchy and gated fuzz sound with a decay that dies abruptly (but still allowing to sustain each note thanks to a bass boost stage that we put at the very beginning of the signal path).

Blend control allows to blend the fuzz sound with the original signal placed in front of the URLA. Clean guitar tone is probably the most basic example in that sense but no doubt the bravest sonic adventures could find plenty of different as exciting solutions (e.g. as "wall of sounds" enthusiasts, we do love to place a shimmer reverb in front of it or some modulation as well to create different kind of textures). Being a fully analog jFET blend, it goes from almost completely DRY (counterclockwise) to 100% wet signal (clockwise).

Dual Resonant Filter is the second effect placed in the internal signal chain of the URLA and it consists in a faithful replica of the analog filter section of the glorious Korg MS-20, simply one of the most famous vintage monophonic synthesizer.
It's an HIGH PASS filter connected in series with a LOW PASS one, both adjustable with their relative controls of CUTOFF and PEAK. Also, we added a dual potentiometer to control the VOLUME of both, which is pretty useful in order to dial with other output levels in chain (including the internal FUZZ placed in front).

You can use the URLA with any expression pedal (by using a TRS cable) to control the cutoff of your favorite filter (HP or LP).
