Good day bass players ! I tried to find some informations about my problem, didn't get anywhere. So i need some advice in order to achieve the best results for my bass tone, without spending too much. I use a peavey T 40 in combination with a Mesa Boogie Mpulse 600, 600 Watts @ 4 Ohms (320 @ 8 Ohms). I'd love to have 2 cabinets with 1x15 speakers, for portabilty and sound (i love 15" speakers more than 4x10 cabs). I'd rather buy used ones instead of new: my budget is 500-600 Euros Please give me some advices. BTW i play a sort of Stoner Rock/Heavy Psych music.
