Compact quality amplifier, great for smaller installation. The ability to lock out the gain controls with the included blanking panel is a nice feature as well.

I know there are hundreds of bass players who use a Tech21 SansAmp or similar to improve their sound. If you do you are are likely inserting it between your bass and a typical bass guitar amp..

I am rebuilding the AV system for a small congregation and I needed an amp to replace a cheap one mounted underneath the podium. I chose this one because of the whisper quiet fans so that I would not have to rewire all the speaker cables by placing the amp in the back.

In it's first use, in a dark club powering a couple Marshall 4x12's, it was tremendous. But I live in an apartment with thin walls, and don't run high levels, much less even own a guitar amp. When I powered the amp at my home workstation with vintage NFM's, I was like, "Oh no!

I had called Sweetwater to inquier about a similar power amp and my rep suggested this one. (Thanks TJ) The other amp had a fan (A little noisy for a controll room) and this one doesn't. I'm using it to power an old pair of NS10's. It's clean and quiet!

It's only been a few weeks, but this amp is the perfect power amp for my 4RU bass rig. Paired with the BBE compressor, the sound is powerful and transparent. I was looking for something like my Gallien Kreuger RB800 only in stereo (with twice the power) to power a 2x10 and a 1x15 cabinet, with...

I provide audio visual to companies and was tired of hauling a ton of equipment.Thinking outside the box, and with the help of the Sweetwater staff, I bought the ART-SLA-2 to be a single space amp to provide power to my 4 space rack.

This is a conventional sled amp in a 1U package. I use it for bass guitar. Couldn't ask for a better sound. It goes very deep, but still sounds tight -- the hallmark of a well-designed Class AB amp with a traditional (non-switching) power supply.

I purchased this amp to monitor my vocals/instrumentation in a live environment. I know this amp in descriptively intended to use in a studio environment but I needed a powerful 1U amp and thought I'd give it a try.

Great little amp. It powers 4 Ohm speakers effortlessly. Unfortunately, since I was using this nearfield, I could readily hear significant transformer hum during quiet passages or no music output. So, the black background isn't as black even as some midfi stuff.
