I use a Basswitch on my wee pedal board and it's a fantastic unit. Two efx loops- (1 series, 1 parallel), clean blend, clean boost, switchable eq, great DI sound tuner out, mute function....
It really is a great 'hub' device that other effects can be routed through for maximum flexibility. I've gigged mine direct into a power amp just for fun and it was faultless.
Here's a great video review
