Which amplifier or PA system?

Experiment! Any amplifier or PA system with an instrument-level input will work. Do not connect Elvari to amplifiers that are made specifically for electric guitar as they usually cannot reproduce Elvari’s output signal correctly. A full-range amplifier for acoustic instruments is required to give Elvari’s tone justice. We have found that the Roland Mobile Cube sounds surprisingly good and loud with our instruments. It weighs only 5.5 lbs (2.5 kg), it is battery-powered and very affordable. The Yamaha THR5A is another good choice if you want more effects built into the amplifier.
