Subdecay Prometheus DLX

I love this pedal. This is the most tweakable and versatile filter I've yet tried, having everything in it from simple autowah through step filters to the pixelated and almost rotary sounds you can get in the Special envelope setting. The ability to trigger LFO speed rather than envelope is great and tap tempo lets you slow the oscillator right down to get very subtle phasey effects or right up to chorus or deep trem, the random step filter is straight out of a sci fi movie, and mixing it up with pixelated on top of envelope is truly entertaining. There is literally hours and hours of interesting experimentation to be had with this pedal, with guitar or bass the variety of sounds available is mind blowing. Shame you can't save a few presets but you can't have everything I guess! A word of warning though, through headphones some of the deeper filter sounds can make you feel quite strange!
