Straight out pitch vibrato is available from this little unit. Similar to the sound of the older Boss VB-2 which is very rare and therefore expensive. There are two mods available: first is to mod the CE-5 to vibrato. The second allows the mod to be switchable from chorus to vibrato via a small toggle switch. On vibrato mode, output A becomes Vibrato and Output B becomes a dry output. On chorus mode the pedal is back to stock.
The overhaul is a combination of a lush mod making the chorus more prominent while reducing noise and smoothing the wave shape.
