I've got a Traynor TC115 and a GB Shuttlemax 6.0 running 375W @ 8 ohms, and I've had the opportunity to use it for a small club gig within the last month just once. It did a fine job, wasn't pushing it at all (no drums at that particular gig). For the time being, this will probably be my main rig, and I'll be branching out into heavier setups soon (2 guitars, bass, drums, vocals, keys). How have other people's experiences been with using a single 115 cab? I don't see myself playing too many outdoor gigs or large venues that don't have PA support, but seeing as I haven't had a chance to really push my rig or compete with more band members for sound, I'd like to get a feel for how I'll fare with this setup. PA support is going to be very common for the places I think I'll end up playing, and the genre of music ranges from soft acoustic and electric jazz to as loud as hard rock. And should this setup somewhere fail me for volume, what's the majority opinion on adding an identical cab (in my case, another TC115) to take advantage of the 600W @ 4ohm spec, in terms of phasing or the sound of 2 15"s?
