The Crate FlexWave FW15R is a two-channel guitar combo amplifier with reverb that gives you crystal cleans and rugged distortion tones, thanks to Crate's FlexWave Evolution 5 preamp with patented Sequential Cascading Gain technology. The Crate FW15R's closed back cabinet produces optimal 15-watt output for the 12" speaker. Stereo input allows playing along with your favorite songs, while a headphone jack allows practice at any hour. Onboard 3-band EQ provides dynamic tone control, while the external output can power an additional speaker. This versatile guitar amp weighs just 15 pounds, so you can literally take it anywhere.
