Greetings! I am relatively new to pedals. Am experimenting some, and slowly accumulating several to go on a future pedal board. I just got a new Mooer Envelope Filter auto wah. It is billed as being both for guitar and bass. It got very high ratings, but most of those were from guitar players. I have tried it on three different active basses, and can hardly get any wah out of it. The only wah I seem to get is if I play some relatively high notes. If I play the exact same groove in a lower (middle) octave, without touching the settings, the wah disappears. I have tried just about every combination of settings possible. Is this possibly an issue with my basses being active? Or did I just make a poor choice for an autowah? Or could this one be defective? I have searched threads here, and most of them seem to be about wahs with expression pedals. What auto-wah would you recommend for active basses? I Would rather get something reasonably economical. Thanks!
