Stephan was great in helping me to make an informed choice. Thank you so much for your great service and your non-pressuring guidance. I really appreciated the opportunity to compare my current amp with the amp I was interested in so I could make an informed decision. Just purchased an Acus Forstrings 8 from Guitar Gallery. This amp is the real deal if you are looking for a super powerful, tonally exquisite and portable acoustic guitar amplifier. Tried it in our large Church and it is more than adequate. I'm very happy and my back is grateful!
