I use them so little i don't even have a 'board' but in my gig bag are the following :-
Visualsound Route66 - Comp and distortion or just clean boost
Demeter tremulator - Just sounds wonderful
Danelectro 'Dan Echo' - Seen by some as unreliable
but fingers crossed ..... it has a good delay range and can emulate tape echo real well.
Anything i can't cover the studio can and to be honest, i'm not the kind of player if you want a wall of Adrian Belew type sound.
