The SolidGoldFX EM-III Multi-head Octave Echo is a tape-style delay with tap tempo and multiple options for the heads, toggled with the switch in the center. Both footswitches have momentary controls for "warp" and "glitch" to emulate the sound of tape and oscillation. This particular EM-III is in very good condition with just some slight wear on the chassis but is fully functional. It does not come with the original box.
