The AT-4 EQ has a tenor size body. This is larger than most Islander ukuleles, giving it a warmer and fuller sound. This sound is also partly due to the acacia top, sides and back. This sound can also be faithfully amplified thanks to the Fishman Kula 201 cartridge. This also allows the bass, mid and treble frequencies to be mixed to taste. The built-in tuner is also handy. Thus, the AT-4 EQ is the perfect combination of a traditional instrument with modern technology.
