A few months ago I got an Ampeg BA-210 to use with my Spector 5-string (strung with LaBella flats). I really like the tone I'm getting but I want to goose the low end just a little bit with a 15" cab. There are several different 15" cabs by Ampeg and since all the local shops are really low in stock (and won't be changing that for the time being) I have to basically guess which cab will be best and just order it sight unheard. BUMMER. Has anyone any advice or suggestions?
