P'MICO (Proggresive Musical Instrument Company) made a variety of stringed instruments including banjoleles. This uke has features that can be found on a few other banjo ukes. The porthole vents on the rim and back can are included on some of the Wizard and Gretsch instruments. The difference on the P'mico is that the back is vented with a raised flat resonator instead of a sealed back like those. This opens up the sound like any of the makes that have this gap for the resonator.
