Vintage 1977 Doctor Q Envelope Follower Electro Harmonix - Video
PUBLISHED: Nov 19, 2013
DESCRIPTION: This is a demo of a 1977 EHX Dr. Q pedal. I'm demoing the pedal with my Telecaster. This is very funky big box pedal from the 70s. When I got the pedal it didn't sound quite right. After remelting some solder joints and replacing the Electrolytic capacitors, it sprang to life.
