I tried a TC Electronics G-Force today. I like it very much, but there is a strange problem. When I set the pitchshifter to track bass ( it's set to track an octave below - like a normal octaver ) and no delay time it makes a strange digital noise. However if I then set the delay time to 8 milliseconds ( ms ) the noise goes away. Does anybody know if this is a problem with my G-Force or is this problem general for all G-Force units ( or maybe other brands of multi FX )???
