Provides amazing, drippy, classic Fender surfy reverb tones

Received one installed in a 1974 Fender Pro Reverb and had to pull it out of the chassis to see what was going on. Provides amazing, drippy, classic Fender surfy reverb tones. Stopped my wife in her tracks as she exclaimed how magnificent the amp sounded, but it was really the reverb that caught her ear.
