GODIN ACS Slim SA VS MultiAC SA: How are they different?
Scale length, number of frets, finish, electronics and significant price difference.
The Slim has a Maple body while the MultiAc uses Mahogany, which is the most notable difference between the two (though both have a Cedar top, which we're big fans of). The radius of the Slim is only 16" compared to 24" in the MultiAc. Also note the LR Baggs electronics and Roland GR compatibility in the MultiAc. You'll pay more for those things, but we're inclined to say it's worth it, even just to have LR Baggs in the mix. We like the Mahogany body as well.
