Dr. Green Doctors Note Bass Envelope Filter
Dr Green · pedal
The Dr. Green Doctor's Note is a bass envelope filter and auto-wah pedal from the UK budget effects manufacturer Dr. Green, designed specifically for bass guitar with bass-frequency-optimized envelope filter sweeps. Bass envelope filters respond to pick attack dynamics to produce auto-wah filter sweeps that enhance bass dynamics without thinning the low-frequency content. The medical naming theme reflects Dr. Green's product line identity.
