Have recently added the Ripper to my Drum & Bass setup (pedal number 17, thank Si!)... It's pretty fantastic. The EQ is awesome... More low end than you know what to do with, plus the Low Pass Filter switch makes it perfect for what I do.
The 'RIP' setting is quite uniquely voiced as well, quite different to other synthy fuzzes I've tried. It also acts like it's gated. It isn't gated, but there's no background noise at all when you mute the strings... Which I pretty fantastic. Very very good pedal. Even without ever touching the RIP control it's one of the best Overdrives I've ever played with.
