I've seen him play many a time with Sublime, LBDA, and now their new offshoot band. Once in a while I see him pull out this little black keyboard (probably with 20 keys or so) that has the sweetest keyboard bass sound ever. It gets pretty low into the frequency range. It's probably some sort of custom job but I'd really like to get that sound without spending 2 grand on a Nord synth to get that sound along with 200 other sounds I'll never use. Any ideas?
