If you can stand a bit of added "Drive" on the effect, get a Cool Cat Vibe. They work plenty nice, me an' my good Pal Bones both love the thing. Be wary of the start up time though, it'd be best to Wallwart it and then put another bypass switch over it (Easy enough to make) so that you don't haveto hit it on seconds before you need it.
Well, unless you just leave the thing on.
Wait, wait, you don't like the Daddy-o?
