Stealth Power Amp

The ISP Technologies Stealth Power Amp is a high-performance floor mount guitar power amplifier designed for professional use. It is based on an analog class A/B amplifier design, providing excellent sonic and saturated clipping performance, surpassing the tone characteristics of Class D power amplifiers. The Stealth Power Amp delivers a true 180 watts RMS continuous output power into an 8-ohm speaker cabinet and greater than 120 volts bridged output voltage swing. It can also function as a stereo 2x 80 watt amplifier at 4 ohms. The compact size of 9 inches long, 4 inches wide, and 2 inches tall makes it suitable for integration into any floor-mounted pedal rig.
