The BOSS GS-10 is a 'guitar effects system with USB audio interface'. It came on the market in 2003. It is no longer in production - but still pretty cool!
Note: historically the GS-10 came after the GT-6 and before the GT-8/GT-PRO. The GS-10 should not be confused with the more recent GT-10!
GS-10 Manager, an advanced editor for the GS-10, is available from the GS-10 Manager page.
By clicking the links below, you can download several pdf files discussing various aspects of the GS-10.
In particular the five files discussing GS-10 effects should also be of interest to owners of related BOSS guitar effect processors, such as the GT-6, GT-8 and GT-PRO.
