Description Product Description Guthrie chose materials and design carefully and what emerges is a guitar using a Roasted Basswood body with a Non-Roasted Birds Eye Maple top, a bolt-on Roasted Flame Maple neck with 24 extra jumbo frets, electronics that use custom-wound Charvel MFB pickups in an HSH configuration. The Guthrie Signature uses a Charvel Tremol-No bridge and Sperzel locking tuners, both of which will allow for heavy tremolo activity.
