Frequently Asked Questions

The active preamp adds clarity and punch, expanding the tonal palette, but can be bypassed for a purely passive, vintage tone.
Switching between serial, parallel, and single-coil modes dramatically alters the humbucker's output and character, offering a surprisingly wide range of sounds.
Yes, a bolt-on neck generally has slightly less sustain than a set-neck, but Sadowsky's construction and wood choices minimize this difference significantly.
