"They came up with this pedal recently, and really enjoyed the original Korg rack. So, the original Korg effect was an SD-3000, which I think I have one way back, and they finally, the Edge wanted that in a pedal. Because it had with its preamp and everything in it, it definitely has the warm sound that comes with this piece. So, I've got one and I love it. I kind of treated it like my Binson Echo, because if you set it on its own modeling on the SD-3000, its very very warm sounding delay, and I wanted one that decayed, and it sort of got a little duller, rather than staying bright. And this does that and as well as many other things. Obviously now, it's MIDI controlled and it is fantastic for my system and I can store as many delays as I want for different presets over there." - Frampton about his Korg SDD-3000 at approximately 56:50 minute mark.more
First-off, this pedal has a very large footprint—like around a 3 x 5090B box equivalent. However, it's very functional, as compared to other pedals that have a ton of knobs and buttons. An added expression pedal will allow control over almost all of the attributes (including button states), which gives this pedal a lot depth. The only real (known) issue is that the pedal's SDD-3000 delay mode brings the input level down a bit (compared to all the other modes), which can be annoying if you're in a live performance situation... There is a built-in input/output attenuator which is useful... I've been using this pedal for about 6 months (practice and live performances) and it really adds a lot of great tone to my setup.
The Korg SDD-3000 digital delay,has 8 distinct delay types. I use this for U2 stuff it really is the business. check out the you tube channels. Endorsed by Dallas Schoo (U2 tech guy). Only had this for a little while so havent been able to really come to terms with its capabilities. Can be midi controlled which these days is a must. Will hopefully do a proper review when I know a little more about it.
