In general, we are seeing fewer and fewer bands using amps. Most of the bands that i know use amps only for live work. In the studio, it's all amp emulation.
Sometimes, an artist will request a certain amp or guitar to be used on their project and there are many studios who have vintage gear on site.
ES Studios in Glendale, California charges $385.00/day (8 hours) studio time and you can take your pick of the gear they have in stock. They have a Stratocaster there called the "Pawn Shop Strat" that is really remarkable.
Here's my take...
I don't want to burn up time trying to find the right amp or cabinet, or the right place in the room for it or the microphones.
The amp simulation is fast, doesn't break down and saves money too.
I've had people compliment my tone on my demos and they ask me to reveal all my tone secrets and I tell them its just a Blackstar and a fake Les Paul.
I've played through Tim Caswell molded Marshall's from SIR and they have been through Hell.
I will use my own amp sometimes on recordings, but most of the time, its more efficient to use Blue Cat Destructor or Avid and just plug into the floor.
You can't tell a real 2203 from the amp simulation, so I see no reason not to take advantage of the new technology...
That's a cheap rate for an 8 hour day. I'll take three. Is the engineer extra?
Seriously, I was thinking after my last post that in your position of being a hired gun at times, a patch is the way to go. You want Don Rich, here you go. C.C. DeVille, here you go. I'm surprised a band would go to a studio without their own gear, planning on using the studio's instead. Too many uncertainties. Why wouldn't you take stuff that you should know like the back of your hand? Then, a good engineer should already know his room and gear, as far as set up is concerned. The only exception we always made was using a house drum set. Nothing pisses me off more than to watch an engineer spend four hours trying to dial in drum sounds. Especially drums owned by the studio that he has already set up three times during the week with other players.
First day in the studio, we always try for all the basics, depending on the number of songs. We would always try for three long days at the start of a project, so we could leave our gear at the studio overnight, and save schlepping it around. Bass player would have his preferred amp and a couple of basses. I would have a JTM, DST30, and Deluxe Reverb along with an SG, Strat, and Rick 12 string. Day two and three, I'd add a couple of more guitars as needed. and they were. At the end, pretty much everything except some embellishment and mixing would be done.
The fun thing about their amps is... when we did overdubs at Q Division for tracks that were laid at Mark Sandman's (Morphine) old loft, I didn't like the guitar part of one song because the old bass player wayyyyyyy overplayed his parts, and the song was a mess. I wrote a new guitar part on the spot, as Rafi set up my Deluxe Reverb with the studio's '64 Deluxe Reverb. Rafi is a wizard when it comes to amp reverb, and had both amps sounding really nice with a couple of ribbon mics, in about ten minutes. We hard panned them and had a nice Spaghetti Western sound going. Another great use of amplifier reverb was when he didn't like any of the outboard gear in the racks, or patches for my vocals on one song. He pushed my vocal tracks into an old tweed Gibson guitar amp that had amazing reverb. He threw a nice old giant tube mic in front of it, and it sounded great. Those are the kind of things I like to get out of my money at a studio. A good engineer who has incredible ideas is priceless.
One of the other things I love about Q Division is, they have one of Michael Pinder of the Moody Blues old Mellotrons. When we recorded "Intellevision", I wanted some Hammond organ and something else added. What, I wasn't sure. Rafi mentioned the Mellotron, and I called a friend of mine who is a gifted drummer, bassist, keyboardist, and engineer (who worked me several times in the past) and asked him if he wanted to play the Moody Blues' old Mellotron on a track for me. Q just had it reconditioned, and it sounds great. He did it for nothing, just to get to play it. It was the icing I really wanted for that song.
I can see the reasons for having the computer generated stuff, but I still really love the real thing. And I know my toys better, and can get the sounds I want real quick.
