Request. To save space I did this using a 3 position on/off/on toggle instead of the rotary switch. You will get the same selections, 10n, 22n and 33n. Well you'll actually get 32n with my toggle but it's close enough, although if you do want it with exactly the same values you could always hand select a 22n cap that is closer to 23n :o) If you want a smaller box than the original, this has the potential to be mounted sideways in a 1590B if anyone is feeling brave, Box of Rock style.
Info about the original:
Create an unstoppable wall of fuzz and vibratory energy, capable of conquering all in its pathway. Its versatile filter circuitry allows for a wide range of tones and textures that allows the Megalith to work well with both guitar and bass.
The MORE HEAVY feature will allow you to cause localized disturbances in the Earth's magnetic field and may cause temporary blurred vision...
So there you have it ... BROOTZ!
