The cuatro tresero is a hybrid of a Venezuelan cuatro and a Cuban tres, allowing both the traditional re-entrant strumming of the cuatro and the ability to pick montunos and melodic lines of a tres. It is tuned in open D (ADF#B), with double courses in octaves for the outside strings.
This instrument was created by Roberto Bonaccorso of Bonaccuatro Instruments, an instrument builder based out of Seattle, USA. It has a solid body of Philippine mahogany, on a center block of American cherry. The decorative details are in purple heart, padauk, canary wood and cocobolo.
It features two piezo pickups, each connected to its own preamplifier and controls. This customized arrangement provides two independent outputs, controlled directly at the instrument.
