No longer available at zZounds
Based on the iconic class A/B power amplifier design, this amp provides excellent tone and saturated clipping. Feed 2 speaker cabs via the stereo outputs.

The ISP Technologies Stealth Power Amplifier is the first True Professional, high power floor mount guitar power amplifier delivering performance on par with the best guitar amplifiers of the day. The STEALTH is based on analog class A/B amplifier design for excellent sonic and saturated clipping performance, not found with Class D power amplifiers and will exceed the stringent tone characteristics of the professional guitarist.

The Stealth Power Amplifier can be used for high SPL gigs and professional stage use. It is powered from an external 19 volt DC switch-mode power adaptor like that used with a laptop but will deliver a TRUE 180 watts RMS continuous output power into an 8 ohm speaker cabinet and greater than 120 volts bridged output voltage swing. The STEALTH can also be used as a stereo 2 x 80 watt amplifier @ 4 ohms. It can power a single 4 x 12 cabinet with incredible SPL volume level output or will power two cabinets in a true stereo rig. This incredible small package will deliver more power to a speaker than the typical 100 watt guitar amplifier and will easily interface with any guitar floor system or high performance pedal board.

The Stealth with 180 watts of power weighs in at only 1.2 pounds, adding meaning to light weight guitar systems. It and also delivers amazing efficiency and it includes internal protection against shorts, open circuits and wrong impedance loads. An internal "power on/off" output control circuit provides pop free operation for turn on read more and turn off. The STEALTH's small package size of 9 inches long, 4 inches wide and 2 inches tall allows it to fit with any floor mounted pedal rig.

I've been looking for a simple power amp solution for quite a while... I use a Line 6 POD HD Pro amp modeler (which I still love!) for my guitar tone, and I quickly grew tired of lugging around 75lb tube amps and 100+lb 4x12 cabs just to run my pod through. I looked at a lot of options---micro tube amps, tube power amps (Carvin), other solid state power amps (Rocktron, Seymour Duncan), combo amps... anything that could reduce the size of my rig but still give me plenty of power for those shows where being mic'd or running my POD straight to board may not be an option. iSP Technologies saved the day with this amazing device. I still can't fully understand how a device so small is able to easily contend with the 100w Tube Amp solution I was previously using. I'll miss the coloring that tubes lend to your tone, but in terms of power: it does NOT disappoint! Probably my ONLY complaint about this device is that there isn't a power switch. You need to unplug power supply to cut the power amp off. I guess an EQ might be nice, too, but you should be able to cover that if you're using a pedalboard or amp modeller. Other than that, this thing is AMAZING and I would absolutely buy again or recommend to friends!
