Got the Worm yesterday. I really dig it, got some good sounds out of it quick. It seems kind of subtle though but that doesn’t bother me. Going to try and pick up the expression pedal today!
It is subtle, but that’s not an oversight. Think of the TREM and VIBE settings as CLASSIC built-in amp tremolo and CLASSIC built-in amp vibrato emulators. Early tremolos and vibratos did not have a lot of depth because of the technology used to create them, but they had very desirable signature sounds.
