These disadvantages may be overcome by a string instrument with a mechanism which switches between fretted and fretless mode of operation with the flick of a switch.
The Mikey Guitar is a revolutionary invention that combines the abilities of fretted and fretless instruments, thus keeping the advantages of each type. This raises and expands the opportunities of the musician, allowing the musician to instantly switch between various techniques while performing.

This one instrument enables the performer to exploit the virtues of both types of instruments while eliminating the aforementioned disadvantages of each.
