Enough Analog Power to Hang with a Drummer

Now it's possible to come by real analog gain and saturation from a pedalboard-sized guitar amp! The ISP Technologies Stealth Ultra-Lite is a Class AB amp/preamp with 90W RMS of gain (180W peak) to drive even a power-hungry 4x12". Enjoy the high headroom and let your pedals season your sound, or drive the input for glorious analog-colored breakup. The Stealth Ultra-Lite is so efficient that it rivals Class D amps in its class, saving your back for the long sets and your expensive half-stack for the studio.

Note: This device is intended to drive a speaker cabinet and should not be placed in front of an amplifier or pedals.

Lightweight and powerful

We love our big amps for the studio, where the scrutiny of the mics and the energy of the performance will live on forever. But for stage use, the ISP Stealth Ultra-Lite prolongs the life of your prized gear and saves you the time and hassle of hauling it.

All-analog signal path

Don't let the Stealth Ultra-Lite hear you call it sterile. This Class AB power amp with tone-shaping preamp section will give life to your pedalboard in a way that only true analog juice can, without the unnecessary weight and risk of hauling your pricey tube amp around town.

Perfect for pedalists

If you're like Sweetwater guitarists, you've spent a lot of time and money getting your signal right on your board— your pedals and power distribution are dialed in, and your tone is on fleek. So why risk coloring your sound with 50 lbs of tubes and circuitry just to get stage volume? The pint-sized ISP Stealth Ultra-Lite gives you a blank canvas for your pedalboard along with plenty of juice to be heard.

Upgraded with preamp and EQ

The Stealth Ultra-Lite sees a number of improvements over of the original Stealth. For starters, its built-in 12dB preamp means it's ready for guitar-level signals straight away, and particularly voiced for pedals. Another improvement is the 2-band EQ section, which offers 10dB of cut or boost in the bass and treble registers to compensate for stubborn speaker cabinets.

  • Portable amp for your pedalboard
  • Measures just 5" x 4"
  • All you need to drive a speaker cabinet

Kicks you in the chest

Don't let the size of this product fool you. I use this as a power amp for my helix with either my 2x12 or 4x12. Loud enough to play with a drummer and play live. Great for the price.
Rated 5/5

Winner

This is a very efficient and powerful tiny power amp. I am currently using it to power a 1x12 to practice and barely crack the volume knob open before it gets too loud. I don't currently have a way to try it with a 4x12 and acoustic drums, but my hunch is that it will have no problems.

Some nice things:
- Tiny
- Passively cooled
- EQ
- Made in USA

ISP is awesome. Well done.
Rated 5/5

Amazing little amp!

I'm running a Line6 Helix into one of these, then into a Matrix Elements neolight 2x12 cabinet and loving the sound and portability. Great, uncolored tone basis for the Helix and loud enough to hang with our other guitarist's 100-watt half-stack. The EQ is extremely useful and at one pound of weight it's just amazing how loud and toneful this amp is. ISP technologies makes great gear.

Killer power amp!

I replaced a 52 pound Peavey JSX head with this tiny Stealth Ultra Lite amp. I'm using it to power a 4X12 Peavey JSX cabinet and it works GREAT. No more tube maintenance or other issues. I'm running an ISP Theta MSX into the front of it and I have all the tones I need and TONS of volume.
