Amazingly high power that can fit on your pedalboard

The Stealth power amp can be the foundation of an incredibly compact yet powerful guitar rig. It's only 9" x 4" x 2", small enough to fit on larger pedalboards. And the Stealth can power a single 4 x12" cab at 8 ohms with incredible volume, or you can use it in stereo mode to send 80 watts to two 4-ohm cabinets.

Smart design sets a high standard for performance

High power aside, the ISP Technologies Stealth is built to incredibly high standards. It's got internal protection against shorts, open circuits, and incorrect impedance loads. An internal power on/off output control circuit also prevents pops when you turn it on and off. In other words, you can count on the Stealth power amp at every gig.

ISP Technologies Stealth 180-watt Power Amplifier Features:
  • The smallest, lightest high-power amplifier for your guitar rig
  • Powers 1 x 8-ohm cabinet with 180 watts, or 2 x 4-ohm cabinets at 80 watts each
  • Internal protection against shorts, open circuits, and incorrect impedance loads
  • Internal output control circuit prevents damaging pops when turning amp on/off
  • Class A/B amplifier provides great-sounding analog saturation and clipping
  • Includes rack ears
Slim down your guitar rig with the ISP Technologies Stealth 180-watt power amp!

ISP is the Best. Have the Theta Pedal for lead tone out to effects and into the Stealth power amp. If you are a lead guitar solo person and are tired of tubes, this is the best. The tone never changes and you can enjoy your playing. I also have the Vector 210 Powered sub by ISP. Its really good. If you want the be all end all solution for lead playing go with ISP for tone, effects a 1 by 12 and a powered sub. Each time I add ISP products it gets better and better.

Power of a stack in the palm of your hand

This is an an excellent light-weight but very powerful amp! I use it primarily with an AMT-SS11B tube preamp in front for a great tube sound with my 7 string Schecter BlackJack and on the back-end, a custom built 2x12 Horizontal recto cabinet with V30's.. From the lowest lows to the highs the tone is very clear! For blues playing i can evoke a classic clean and pure BB King tone, or Anthrax style bring the noise metal. The ISP kicks those Celestion's around without breaking a sweat! Word of advice: The Stealth is powered by a laptop style power-supply that plugs into the back of the unit. The power-supply does generate a lot of juice and if you power up the supply before plugging into the amp - you will get sparks. So just connect power supply to amp before powering. Saving the best for last(for me at least), i purchased this as a Sweetwater DealZone demo for half the retail cost which included original box, power-supply, rack ears and the full warranty!

Large Sounding Power Amp

This was the perfect power amp for my GR-33, wireless Ghost Convertor and TriplePlay guitar control for my floorboard. And this power amp powers my Matrix cabinets (running stereo) giving me a crystal clear synth sound.

An Awesome Power Amp, Clean and Clear... thanks again ISP!!

Simple and easy to use. Clear transparent power. It's muscling around a huge 2x12 cab like it's a rag doll. Make my ISP Theta Preamp rack sound like Godzilla. It's one bright blue LED eyeball stands out beautifully against the black metal and white lettering. An awesome piece of gear. The folks at ISP Technologies never disappoint. Proud owner of many of their items and the company is as top notch as it gets. Thanks to my sales rep, Bart, for making a smooth transaction... got it here sooner than I expected!

Big Sound Small Box

The ISP Technologies Stealth 180-Watt Pedal Board Power Amp is ideal for demo's my company does for our guitar picks at trade shows, and other events where size can be an issue, we use it along with Sweetwater's Eleven Rack and ISP's 12" Cabinet to produce any amp sound or tone the potential customer is looking for. This amp produces a perfect clean sound that allows the Eleven Rack really shine. It is small, lightweight and durable, extremely happy with it.
