The Flamma Envelope Filter is a fun and surprisingly versatile pedal. It reacts really well to picking dynamics, giving that funky quack and sweep when you dig in, but it can also be set more subtle for a smooth auto-wah style effect. Controls are straightforward but give enough range to shape the response — you can dial in tight, snappy tones or more open, liquid sweeps. It works great on clean funk rhythms, but also adds character to overdrive and fuzz. For the price, the sound quality and build are excellent. Definitely a cool tool if you want some funky texture or a touch of wacky psychedelia in your sound.
