Sound: The Acoustic SFX is a beautiful sounding amplifier, with enough control over the EQ to reign even the boxiest sounding instruments, but the real magic of the Acoustic SFX comes in the stereo effects. Spanning from short slapbacks to long clear delays, to washy immersive reverb, the effects on the Acoustic SFX are stunning. The side-firing speaker is incredibly useful for filling a room and giving the impression that you’re hearing more than just one amplifier. Using the SFX control knob, users can adjust the width of the stereo effects such as hall reverb and delay. The Vibratone effect was a fun surprise, modeling the 1960’s Fender spinning speaker answer to the Leslie cabinet. For both vocals and guitar, the Acoustic SFX is a standout for the stage in sound and looks.
