A big part of the B15 sound is the cab design and a 15" speaker that has some breakup at 35 to 40 watts...i think i know where you are going but i would plug the head into several cabs, maybe not even a single 15?...in my Gemini II i have tried many 15s; EV to CTS to Eminence and Jensen...wound up with a 70s Utah 15 out of a Fender Bassman cab but its a open back cab...go figure...the issue is many modern 1x15 bass cabs are designed to go low with power which a 50 watt B15 clone is limited to push low hz...adjustable hpf filter is how i would go to take advantage of the limited power (even in a studio).Thanks for the info. Yes. You’re right. Although my sort of clone is 50 watts.
I don’t gig, so most of the use will be studio and personal use. Jams. Weight is a factor for my old bones, so I know I’m compromising a bit on the B-15 sound, but I can live with that. Old school cabs just aren’t an option for me, particularly with so many great newer options. Cheers.
