The Aloha Twin is an internal double-sensor pickup specially designed for the ukulele. It is based on the same technology as K&K's award-winning Pure Pickup.
This pickup system has a strong output signal and works nicely even without a preamp. Please keep in mind when playing without a preamp, the results depend somewhat on the quality and type of the amplification equipment. For more tone control, the external Pure Preamp would be a great choice with its clean musical EQ and small size.
