I just bought , new , a Morley PBA-2 dual bass wah . On regular wah mode I only get effects on the G string . When I switch it to funk mode I pick up effects on the D string too . Seems like since it was made for bass I'd get more out of it . I'm wondering if I'd be better off with an envelope filter such as the DOD FX25 like Flea uses , any ideas on how I can get more out of the Morley ? Or go with an envelope filter ?
