Designed for gigging guitarists and bassists, the IsoAcoustics Stage 1 Board isolates and decouples your combo amplifier from the stage, thereby improving its tonal response. It's particularly useful in improving the bottem end, as the device can aid in tightening up the bass frequencies by reducing or eliminating comb filtering—a phenomenon which can wreak havoc on the lows.
It's not called the Stage 1 Board for nothing: the design is an upgrade of a previous version, which required the use of separately sold isolators to achieve its full potential. In the Stage 1 Board, the isolators are built into the unit, so you don't have to make two purchases.
The unit isn't just for the stage. It will improve performance in your home or studio as well. It will support combo amps up to 100 lb.
