The Tremol-No is a patented add-on for guitars with a tremolo. It allows guitarists to turn their tremolo unit "on" (so they can raise or lower the pitch of the note with the tremolo unit) or "off" (where the tremolo unit doesn't move at all; no lowering or raising of the note pitch via the tremolo system). Allparts is the exclusive distributor of Tremol-No products. Check out Premier Guitar Magazine's review to learn about what the pros think.
Buying the right Tremol-No is easy - just match your trem block to the images below.
