Plug in the Full Circle and the sound of your upright is all there. Whether its big, fat and punchy fizz, full-voiced acro or slap, youll hear all the acoustic qualities, dynamics, and nuances of your bass - only louder. Encased in a sturdy aluminum height adjuster wheel, the Full Circle offers accurate, transparent sound. To match the pickup to your instrument and playing style, a fine-tuning feature lets you quickly choose between an open, resonant response or a drier and more focused amplified tone. The Full Circle is a quick retro-fit on instruments with 1/4-20 thread height adjustment wheels. A Pro-EQ Platinum Bass, Pro-EQ II or B-II preamp is recommended, but not required.
