The Spirit line (or more accurately "Spirit by Steinberger" line) are all-wood copies of the original Steinberger models.  Designed as economy versions of their graphite counterparts, they offer some of the same benefits of the original line (headless necks, double ball tuning) at entry level prices.  First introduced by Gibson in the mid 90's, they are still produced today and can be purchased exclusively through MusicYo.

This site is designed primarily to explain and feature the all graphite and graphite-neck instruments.  Some of the options on the Spirits are the same, and those are referenced on this site.  For other Spirit-specific options and features, check the MusicYo website for details.  They can provide full specs and support on these instruments.
