On the Mesa Boogie pages of Whotabs.com Pete is quoted to have said "MESA/Boogie have made a very good front-end tube preamp, and I’m using four of those. It’s the best I’ve ever tried; I’ve tried literally everything on the market..." in the October 1989 issue of Guitar Player Magazine. Towards the bottom of the page a photo of Pete's 4 Studio Preamp equipped rack is shown. The who's stencil can clearly be seen on top of the rack.more
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.
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!!!
