Classic studio preamp

Sounds amazing.

As a recording Preamp, it sounds better for guitar than going DI into a mic preamp like the Heritage Audio 73.

If you want a Nirvana or Green Day type of distortion tone, this is the preamp to get, along with a DS-1 or DS-2. If you want a slightly thinner, but arguably better distortion tone, plug a Digitech grunge tone directly into a power amp, and it sounds almost exactly like Journey's tone. Judging by Youtube videos, the ADA-MP1 might be a better and cheaper preamp than this Boogie, esp. if you like 80's rock. The studio preamp is more 90's sounding.

Randall Smith, the founder of the company is also cool, because he basically invented high gain and master volume, so without him, Metal wouldn't exist, or if it did, it wouldn't have happened as quickly. Also, I'm just a huge fan of master volume, because I like to play with lots of distortion without going deaf, and master volume makes that happen.

Mesa Boogie Studio Preamp-Wouldn't Have Anything Else

For 18 years I was a freelance touring guitarist Over those years I've gone from one extreme to the other- from using old Fender tube amps, Torres engineering hand-wired, point-to-point wired stuff- all the way across the spectrum to using a Johnson Millennium for a couple years, and even tried an Avid "Eleven"-ugh! The music I'm often hired to play requires that I use a lot of effects and/or to use my guitar as a midi controller for rack-mounted synths, and the idea of running a guitar signal into one or more multi-fx units before it gets to the preamp stage of an amp is counter-intuitive to me. Therefore, an amp having an effects loop is necessary to me. I gravitated to Mesa Boogie amps- great tube amps WITH effects loops. I bought the Studio Preamp primarily because of its excellent-sounding "recording out" circuit, compared to any other I've heard, which enables me to elegantly go into a full-range system, with my Eventide "Eclipse" in its effects loop, into a sub- mixer with rack mount synths, and just tell the stagehands "I need no mics, just 2 DI's" Or, I can carry a Cabinet or 2 of appropriate size to be mic'd if I'm not using synths. I can't imagine using another preamp. I have two, just in case one goes out. And I'm always worrying that 2 isn't enough to last me the rest of my life.

Mesa Boogie Studio Preamp

From crystal clean to absolute high gain and everything in between, this 2 channel, hand build all tube preamp delivers. Plain and simple. You will just need some time and fiddling to figure out its sweet spots, but as soon as you find them you will have a huge arsenal of sounds, to play everything you want. Metallica, Nirvana, Dream Theater, The Who are just a small sample of great bands with legendary tones who used it both in studio and live. I personally own one for about ten years now and although it's made at 1989 and still running on the original tubes, it never let me down and I don't think it will any time soon. Its notorious, American made Mesa Boogie build quality, is beyond any criticism. All in all, a great sound unit ready for recording, live shows or your bedroom, this thing is an absolute tone beast!!!
