Kramer the Duke... Great tone, but oh dear.
- Temperature-sensitive neck. It's aluminium; it changes length with temperature. So it goes out of tune, quickly.
- The bridge... it's a BBOT with the strings run through it at an angle. That means that if you put roundwounds on it, the E-string can't be tuned correctly, because the winding of the string catches on the edge of the bridge.
