The new STEALTH ULTRA-LITE™ is the first ULTRA compact, high power guitar amplifier with a built in preamp allowing direct interface with small signal foot-pedals. The STEALTH ULTRA-LITE provides 180 watts Peak, 90 watts RMS output power into a 4 ohm load. The STEALTH ULTRA-LITE™ is based on ISP Technologies patented Dynamic Adaptive Amplifier Technology and delivers nearly 60 volts peak to peak output signal swing from a 19 volt DC power supply by use of stored energy. The built in preamp is designed to allow instrument level pedals to directly drive the STEALTH ULTA-LITE to maximum output level plus you have the added tone shaping capability of +/- 10dB bass and treble control providing up to 47db of composite signal gain. The flexibility of the STEALTH ULTRA-LITE built in preamp also allows direct interface with professional +4dB rack mount signal levels.
