Ok, so i'm building up my bass rig, and thanks to a very healthy tax rebate i just got,i've decided to get a cab to go with my warwick profet 3.2 head (300w @ 4Ohms) I am playing in a blues cover band and we have a gig coming up in a couple of weeks so i'd quite like to have my cab by then.The blues bar we are playing is TINY(max capacity of 30 people!!) The main factors i want are i want that cab to be light, sound good and not too big size wise. My initial though was to go for a 2x10 cab, but i was also thinking of possibly (if i can source one at a good price) going for a Phil Jones Pirahna 4B. Does any one have any suggestions or does anyone use the PJB cab with a different make of head? how do they go together?
