my bassist has an ampeg B2-R head and a 1X15 classic cab. he is wanting to get a good solid punk bass sound out of it. somewhat on the mid range side of things with clarity to make hot bass licks shine through.

the EQ bands are (+/- 12dB): 40, 80, 150, 300, 600, 900, 2k, 5k, 8k

and hes running a fender P bass 4 string through it (passive).
