Envelope filter based on Mutron Micro V fully moded into a more versatile and easy-to-build pedal. Fully responsive to your pick attack.
Including additional Attack and Decay controls for the envelope response. Featuring an LM13700 in replace of the unobtainable CA3080 in the original circuit.
The Vutron V is a modern take on the envelope-controlled filter device designed to combine the Mu-tron V’s simplicity with the capability and versatility of the Mu-tron III.
We have included Decay and Attack control for this circuit to allow a wide range of effects suitable for a funky bass guitar, a screaming lead guitar, or anything in between – including electric keyboards and electrified wind instruments.
Also, we have replaced the unobtainable CA3080 with a much easy to source LM13700 (the same one you might have use for compressors such as Sea Lion or the Master Phaser) without any tonal impact.
This compact design is suitable for a 1590b or a 125b enclosure.
Without a doubt, this pedal will deliver all touch-controlled wah effect (autowah) you always wanted and more! This is definitely a must-try if you are interested in getting crazy psychedelic sounds out of your amp!
- Range: Controls the intensity of the envelope dynamics generated by your pick attack. Fully clock-wise, the greatest the sensitivity.
- Attack: This pot works in direct relation with the Range knob, allowing you to set the fine adjustments on your pick’s attack.
- Decay: With this knob, you can control how long it takes for the envelope to sweep the filter. Higher settings will give you a longer decay time.
- HI/LO: This toggle controls the range of the filter that’s swept.
