Acoustic Image Clarus S4plus Instrument Amplifier Head

Call to order

The Clarus Series 4plus 2-channel amp gives you the same world-class clean tone and massive headroom as found on Acoustic Image's other great amps, except you can hook the Clarus up to just about any speaker cabinet or PA speaker you wish!

Don't let its compact size and light weight (only 5 pounds!) fool you--the 600 watt Clarus S4plus packs a punch. Its crystal clear, transparent tone brings out the best in acoustic or electric violins, violas, cellos, double basses, guitars and even keyboards!
