The "Slim" in the moniker refers to the 1.715 in. neck width at the nut, which is a mere 16th of an inch wider than Godin's standard electric guitar nut width. If you do most of your playing on a guitar with a fairly narrow neck (most solid-body electric guitars) this is the ACS-SA for you. The slim neck of this guitar along with the Ergocut shaping technique and 16 in. fingerboard radius provide for a very easy transition for steel-string guitar players looking to integrate nylon-string guitar sounds into their music. Aside from the new neck, the ACS-SA Slim shares all of the same features that have made the ACS-SA an industry standard. The chambered, Silverleaf Maple body with hard Maple top results in an instrument that is virtually free of feedback, making it easy to use even in loud stage situations.
