Hartke has taken its experience in building great sounding bass amplifiers and brought it to the field of acoustic guitar amplification with the introduction of the Hartke Acoustic Ribbon Series. Perfect to go from the coffee house to the night club, the AC75 is a two channel 75 watt acoustic guitar combo.
The AC150 features a 150 watt tri-amped design, with 50 watts powering the left and right full range speakers and 50 watts powering the high frequency ribbon tweeter. To reduce feedback, there is a phase switch on channel 1 as well as a variable notch filter with depth control.
