A couple more builds to show.
First up is a Mad Professor ‘Deep Blue Delay’ clone I built up. The filtering is a bit more severe on the repeats than a stock Deep Blue Delay, giving the repeats a ‘warmer’ sound. I went for a ‘Space Echo’ look on this one, and think it came out pretty cool:
Next up is a classic DIY FX project; the AMZ Mosfet Booster (see here for info and schematic: http://www.muzique.com/schem/mosfet.html).
This is a clean boost, using a Mosfet transistor (BS170, just like the ZVex SHO), however, unlike the ZVex SHO, it doesn’t crackle. Overall I think its a far nicer boost than the SHO circuit is.
I built this into a 1590A, a super small enclosure. They are cool for things like buffers, boosts etc.
