The wonderful pedal of dave's

Yeah, I'm pretty sure this isn't a real effects pedal. I assume he has a synth keyboard or something hooked up to the volume pedal he uses. if you notice, before he changes from the initial Gm to Dm (or whatever the next chord in that fantastic song is..) he pushes a separate pedal. I assume this changes the chord programmed into the synth.

Though this is purely guesswork...

As far as I'm aware there are no pedals which can recognise a chord and sustain it forever, though you may be able to get a similar effect with one of roland's guitar synth pedals...

Anyway, my solution is to teach a random person off the street three chords, buy them a keyboard and wahay, you've got yourself a nice backing track to solo like mad to.

You can achieve this with a midi guitar system. This is a special pickup fed into a synth box that transforms its signals into midi messages, which are send to whatever midi device you like (mostly synths).

Pat Metheny uses this much in his early 80s alums.

Actually the pedal David's using is a custom-designed delay. There is no synth involved.

As far as I knew, it was a Pete Cornish Soft Sustain pedal.

Pete makes them for about $450.

AFAIK

Ive seen Steve Morse play with a programmable synth amp, he plays a rythym section, recording whilst playing, then he hits the amp and it plays what he just did, seen Steve Vai do something similar

The exact model used is a Roland SDE-3000 delay, customized to give super-long delay (I think).

gp to petecornish .com David uses ALOT of his pedals(actully they are made into huge pedal boards). Mr.Cornish has worked with David for years and is responsable for a very large portion of the Floyd guitar sound.Fair warning though: the Cornish pedals do not even come close to cheap.
for me it is dream gear, I seriously covet everything on that site!!
