I use an MI Audio Boost n'Buff with my LSS and I can't recommend it enough. It has a great buffer which helps retain highs and the booster is excellent. Up to noon on the dial it is a clean boost and then past that, it is a treble booster. I have version 1 but on version 2 of the B n'B, you have separate gain and volume controls. Treble boosters and dark amps like the Lonestar are a great match!!
