If you"ve been looking for a great, affordable Cigar Box Amplifier to go with your Cigar Box Guitar, then look no further!These great little amps are hand-crafted in the U.S.A. in C. B. Gitty"s workshop in the foothills of the White Mountains in New Hampshire. Their heart is an Artec SDA-T 2.5W amp board, which is powered by a 9V battery. The amp accepts a standard 1/4" mono guitar cord as input, and output is through a 3.5" 1W speaker. A red LED power indicator is included to help prevent accidental battery drain. These little amps put out a very respectable sound, and in our opinion are much superior to the smaller half-watt and one-watt amps!The dimensions of this amp are: 4.25" wide x 8" high x 4" deep. The box is an all-wood Oliva Serie G cigar box. This amp is one of C. B. Gitty"s "Production" models, where many identical amps are built to a specific design. Each of these production models is designed and signed by C. B. Gitty himself, so you know you are getting a great item!C. B. Gitty selects the nicest, most suitable smaller cigar boxes as his amp cases, and then dresses them up with all sorts of great features, such as those seen on this amp: Stylish, distinctive all-wood natural finish Oliva Serie G cigar box; Beautiful gold Swirl Speaker Cover; Panel-mount tone/gain control; Gold On/Off/Volume and Tone Knobs; Externally accessible battery tray holder; Beautiful shiny gold box corners; Protective rubber feet.For those of you who are interested in tweaking your CB amp, and aren"t scared of a soldering iron, the amp board also provides connection points for an output jack and headphones jack as well!
