Keep core amp changes underfoot with the Blackstar FS-11. Its metal-housed, two-mode design is made for the ID:Core Stereo 20 and Stereo 40. In Mode 1, it handles two-channel selection plus effects on/off. Switch to Mode 2 when the job is moving through patches saved on the amplifier: switch one steps down, while switch two steps up. It is a focused controller for players who use those onboard amp controls during a set.
