If you are after truly cosmic sounds Id go with a delay and ....flange, wah, phase and well the full monty really !

I have a Boss DD6 at the moment and that is Ok though I know some people find it too digital. The Line6 kit is nice to.

I had a DD3 before some scum-bag stole it and that was great.

The Digitech delays are also OK though if you relay fancy sounding like a Space Hippy, I'd go for a Digitech combo like the RP series or the GNX series.

IMHO the Ibanez ones sucked (mind you the only bit of Ibanez kit I have ever liked was the turbo tube screamer !).
