Hi Kev
Ive just bought one of those radial bigshots, not tried it yet though as ive no amp at the mo!!! its built really well and has a tuner out and mute facility, and a volume control on one channel ( to bring the louder instrument down) and a three position bright switch, its passive, too and quite small, mind you when i had my NS wav4 i used an EBS microbass2 which worked fantastically, a bit more cash though, and maybe more bells and whistles than you need!!! the radial seems great though ill update you soon, they are about £80 i was lucky and got one off old horse murphy , top fella- all the best mate - lee
