The AG150 loaded with the ViolAmp speakers is the best amp I have found to amplify the acoustic mandolin.
Amplifying the acoustic mandolin has its fair share of problems. Tone and gain before feedback have been my primary hurdles which have now been solved by the AG150/ViolAmp conversion. The quality of sound coming out of the amp is exactly what I hear coming out of the tone chamber of my mandolin wether I use a transducer pickup or dynamic mic. And I am sure that a condenser mic will really shine once Phil releases his compatible 48v PSU. As far as I am concerned, this amp is the best way to go . This lightweight, intuitive and tone efficient amplification for the acoustic mandolin has been the best investment in sound reinforcement I have made.
