Great sound, especially for guitars

Sebsweden, 13.06.2014
I have been using Studio Projects microphones for a long time, really liking them, so I was very interested in trying out their preamp. And for the low price, it wasn't much of a gamble.

The sound is very "analgue-y", but clean. It doesn't add fuzz on top like other cheap preamps, as long as you don't turn up the "tube-blend" button. This adds the type of fuzz that is easily added in any DAW (if you like that sort of thing). I haven't experienced any hum or crackles, the build quality seems fine! The power supply is really big and bulky.

Where this preamp really shines is as a guitar preamp. It adds weight and excitement to my Telecaster, and I can hear details in the sound that i never heard before. That's what a good preamp is supposed to do. Using it with a Microphone works fine to, but I noticed a slight loss in low frequencies. The preamp has a "mid-forward" type of sound, though nice, doesn't work for everything. I can't think of a better preamp for acoustic or country music.

The connections where a bit tight at first, but became more manageble with use.

All in all it's much better than other preamps I've used up to 400EUR.

Quality and price

Maxim K., 08.05.2013
I can definitely recommend this microphone preamplifier.
It has a nice character that does nice work especially with condenser and ribbon mics. I have used it for several purposes and have found it to be pretty versatile but my favorite use is brass and speech. The tube blending option can be very useful, but I have found most of the time I don't use it much. I keep it on about 50% of the time. Once again i suppose tastes apply here.
Especially for the low price there are all the options you could really ask for in a microphone pre-amplifier. Phantom power, phase reverse, mic and line in/outs, Hi-Z (could be better) in, and a way to color your sound (tube blend section).
The unit is metal and solidly built. I have another one for about 5 years now and it has held up well.
The knobs are fairly sturdy compared to what I'm used to seeing at this price point. I don't think overall it's any less durable than some of my upper end pre-amps, with normal studio use or even some field use. It's doesn't have the same "quality" feel to the knobs, plugs and switches as some pricier units, but for the cost these are small issues to me. I don't think there would be any problems with this unit holding up for a long time.
I feel like this unit is a fantastic deal. It's not perfect and it's not able to compete in every way with "high-end" units, but it does what it's supposed to do and does it well for an awesome price! For a pre-amp that costs so little, I am impressed with how it performs. It's all about taste I supposed, but I have tried a lot of units in a similar price range and even a little more and hated them all. Preamplifiers can be like microphones, options are always good and having a variety can save the day. It's nice to see there are companies making affordable options so those of us not gifted with a large bank account can still have choices.
