Marshall Combo II - Instrument Amplifier w/PreAmp and Pickup

Marshall/JHI (Mini-Amp/PreAmp) COMBO-II complete with a built-in, switchable preamp stage! Small enough to clip to a pocket or your belt (about 4.5" x 5.5" x 2.5"), it is powered by a single 9-volt battery, or use the included AC adapter to save battery power. Simply press its "electret transducer" pickup onto a tuning peg on your harp, and select the AMP mode. Then turn your COMBO ON, and play to be heard... any time or place... free from all wires, microphones, and other audio systems! You can also choose to play your harp through another instrument amplifier or a larger sound system by selecting the PREAMP mode. You will need to use a length of 1/4" mono-audio cable to start playing. NOTE: The PreAmp addition was engineered and designed by Jubilee Harps, Inc, as a modification of the Marshall Mini-Amp MS-2. Renamed the COMBO-II, it is available exclusively through Jubilee Harps, Inc., and is patent pending.
