Hi all! Is there any difference between using the 4x10" combo or the 2x10" combo plus 2x10" extension cab? (except for the latter being more expensive) Also, would it be better to add a 1x15" cab to the 2x10" combo instead of a 2x10"? I'm into the bass sounds of bands like Rush, Stranglers, Cure, Pumpkins, Muse. My main bass is an active 4-string Ibanez MC900, but I also play a passive 5-string Warwick Streamer 'Rockbass'. I also use effects such as Octaver, Overdrive, Chorus on my Boss ME-50B. A store in my town's got an Ashdown sale on, and I'll definitely go and check the stuff out, but I also thought it won't hurt to get my fellow TBer's input. Thanks guys! V PS: I've done a search, and I'm pretty sure that the 1x15" combo's not the right one for me.
