Just finished my Tremolo build. Everything works as it should, except there is a bit of distortion. I play clean in bypass mode. The volume is about half, equal to the bypass, and the speed and depth set a little less than half. With the pedal on, there is minor distortion especially on the low end. Is this common with this pedal?
Common, no, but it has happened from time to time where a hot input signal will in fact cause the trem to get a little distorted. If you're getting a lot of distortion, or getting distortion from vintage single coils or something, especially with no dirt pedals in front of the trem - I'd say there's something wrong with the build.
What's feeding the trem when it's distorting on you?
Clean inside, dirty outside is how like i like 'em!
