Here's a killer Fretless Wing bass played though a Mu-FX Octave pedal. Doug Koeppen and I wanted to try playing the bass through an octave pedal to make it sound more like a normally turned bass.
This Wing Bass features a Black Limba/Korina body, Fretless Rosewood lined fingerboard, a Bartolini pickup and Piezo Hipshot bridge pickups and Hipshot hardware.
The other great thing about Wing basses is that they are available in any and ALL configurations.
4-5-6-7 string and even 8 string custom and all are available fretted or fretless.
