Digicarrie Designs MNGRL Advanced Wavefolder Effects Pedal

The MNGRLR is a diode-based wavefolder that can fold your wave up to 5 times! It works by using a diode ladder to split the wave into 6 parts, and then inverts the direction of
every second part. At low gain, it sounds like a raygun, and at high gain it sounds like a car crash. 

• Fund: Controls how much of the fundamental frequency is mixed in. Basically, how prominent the original frequency is compared to the other parts of the split wave.Shape:
• The mixed balance of the inverted and non-inverted parts of the wave. At 12 O’clock, the wave parts are mixed equally. This changes the mix of harmonics, though it is fairly subtle. It’s most noticeable on synths or drum machines. 
• Fold: The input gain of the pedal, which determines the amount of wavefolding.
• Smooth: A low-pass filter to help tame the added high frequencies. 
• Wave: A dry blend to mix in some of the original signal.
