Thanks for the link! I'm reading up on circuits, etc and that'll be a good goal for me. Besides shrinking the footprint, I think I can simplify the circuit easily - there's an on/off toggle for power AND the effect along with an input jack for a footswitch, all taking up real estate. Unless someone can think of a clone, I'll pull this over to the DIY section.
Yeah you could quite easily re-wire it so the input jack works as the on and off and then just the footswitch to turn it on or off... if I can find a sound sample and it seems worth it I may consider building one up.
I'd suggest moving it to DIY though, it's a fairly generic phaser in itself but I don't think it's been cloned specifically.
