I'm someone who likes plugging into the FOH through a DI and letting the house subs carry the low end and I just use monitors to hear myself. This works when the house has a nice sub or array of subs, but I know that's not always the case. I'm not sure what kind of venues generally have subs and what ones don't. If a place doesn't have a PA that can really pump out the low end, I assume the best route would be to use a cab. What I want to know is, how big of a cab do you need to compensate for the lack of subs? Obviously that will depend on the size and type of venue, so what's a safe bet to cover my basses (sorry, had to)? Edit: Just realized this should probably go in the amps forum, let me know if I should move it and I'll delete this.
