As a live sound engineer I’ve encountered and used all sorts of amplification systems for acoustic instruments, from powered PA speakers to Roland keyboard amps to various dedicated ‘acoustic’ amplifiers. When I first started out in the early 2000s these usually resembled electric guitar amplifiers, but with fullrange drivers, perhaps a tweeter or two and a control panel that included a microphone input. Typical of these was the Marshall AS50D, which was good and loud but definitely on the heavy side at 16 kilos/35 pounds. As time has gone by, live sound equipment and instrument amplifiers have both become more compact and lighter in weight, and in May 2022 I decided to purchase a Blackstar Sonnet 60 to see what the state of the art was.

Coming from old-school acoustic amps, a couple of things that impressed me from the outset were the size (345mm wide x 310mm high x 250mm deep, or roughly a 1-foot cube) and the weight of 7.7 kilos/16.9 lbs. This was significantly less than the 10.5 kilos/23.1 lbs of the Boss Acoustic Singer pro, another amp I was considering. When you are carrying guitar, microphone stand, cables, power extension etc every kilo makes a difference, especially in Singapore, where load-ins often involve stairs and narrow doorways.
