I've been a professional acoustic soloist for 12 years and the Blackstar Sonnet 120 is the perfect amp for small to medium size gigs. The external footswitch is necessary for the mute function but well worth it. The speaker stand adapter, along with the unusually high headroom, makes placing the amp extremely easy, even in a small space. The bass response is amazing. Very strong low end without the 'hum inducing boom'. When you dial in your sound on the Sonnet, you can clearly hear the effect of each knob. In other words, each knob does it's job obviously yet evenly. The guitar sound thru the Sonnet is more natural than any other amp I've tried. (I've been using the Fishman Artist and Performer for the past 4 years. Very, very good amplifiers.) The vocals come thru the Blackstar Sonnet 120 with clarity and the overall sound of the amp carries very well. If a 180-watt version comes out, I'd buy that one in a heartbeat. Blackstar products are among the absolute best on the market.
