The Brass Mini Acoustic Strap Secure is a dream come true for acoustic players with pickups in their guitars. The USA spec model's 3/8-32 inch threads go right onto Fishman, Switchcraft, K&K output jacks and more. The M9 metric version fits L.R.Baggs, Shadow and others that the original US thread does not.
This new 'Mini' format follows the same principles as the original - simply unscrew the factory strap button, attach your strap to the Acoustic Strap Secure and thread it onto your output jack. The manufacturers have improved functionality by reducing the overall size without compromising function and allowed a little extra room on the inside diameter for a better fit.
