The STEALTH ULTRA-LITE™ offers efficiency close to that of a Class D amplifier but has the great tone and overdrive clipping characteristics of a Class A/B analog power amplifier. The STEALTH ULTRA-LITE™ weighs less than one pound, but packs the performance of a true 90 watt guitar preamp / power amplifier all in a package size of 1.73 inches tall by 4 inches deep and only 4.9 inches wide.

Drop the STEALTH ULTRA-LITE™ on your pedal board and end up with a true compact rig with enough power to play with a drummer on stage. The STEALTH ULTRA-LITE™ will deliver a true 90 watts RMS 180 watts peak into a 4 ohm load (60 watts RMS 120 watt peak into 8 ohms) and comes with a universal switch-mode power adapter that will operate on any line voltage between 100 and 240 volts worldwide.

Tour with confidence knowing that the STEALTH ULTRA-LITE™ will operate anywhere in the world, on any AC mains, with the included universal power supply. ISP has also designed in Pop free operation with protection against shorts, open circuits and thermal runaway.
