what are you using for live shows?
My rig consists of:
Peavey Tour 700
Fender RT-1000 rackmount tuner
Behringer Composer Pro-XL MDX2600 compressor
Sennheiser FreePort wireless system
i got that all shoved into a rackmount case from some off brand thing... i have no idea who it is lol
My cabs are:
Fender bassman 410 and a Peavey 15'
I was running 8x10's but i was using some cheap crate cab as my other 4x10 and just was not digging it so i started using my guitar players spare 15 and everything sounded great after that.

All the low end come from Dora the explorer. I swear by it.
