Our mission: Create a series of best-in-class acoustic guitar amplifiers, designed to deliver fidelity, performance, and great vibe. They are ultra-portable and versatile, yet quite uncomplicated. We surveyed a wide swath of acoustic guitarists to find out what they really wanted in an acoustic amp. The near-unanimous response was: "Light and loud, as portable as possible, with great natural guitar reproduction, vocal mic fidelity, and a selection of tasteful effects. It needs to look cool without being too flashy or delicate. And it needs to be simple to understand and affordable to purchase." The Acoustic SFX II amplifier delivers best-in-class performance for acoustic guitar and vocals. This powerful, portable system has two channels designed for instrument or microphone use, each with studio-quality effects enhanced by our proprietary Stereo Field Expansion technology for room-filling, more-than-stereo imaging. Bluetooth wireless audio streaming and a 90-second looper make it perfect for solo shows.
