- Take their money.
- Let them deal with trying to sell CD's with poopy tone.
- Spend their money getting cool gear.
- When they can't sell any CD's, they blame you, and never come back to record with you. So?
- Any of their money you didn't spend on cool gear can get you enough alcohol so you forget the whole mess.
The problem with this approach, of course, is it's very easy for them to say, "Well, so-and-so recorded this, and the guitars sounded awesome in the room. His mixing just sucks, don't record with him." A great way to trash your reputation, especially if you're young (which you are) and don't have an extensive catalogue of recorded work under your belt (which I'm guessing you don't).
Couple ways you could go. One is WhiteStrat's suggestion, where you just make them listen back to the tone in the mix, and hope they get more flexible after that. If they hear it, and don't like it, then you've got some credibility suddenly. If they hear it, and DO like it, well, whatever, it's their tone.
Also, if you've got the time/they've got the money, let them track the guitars the way they want, and then say something like, "You know, the guitars don't sound quite full enough to me... Let'
s quad-track them, except to make them a bit bigger let's use a lower gain, brighter sound to compliment the high-gain, darker sound you've already got. All the big bands do this." Not only is that
true, it also gives you the option to simply mute or mix back the super-high-gain tracks and let the double-tracked lower gain sounds be the primary tone.
This also works with Farview's point - if they're hearing their wall-o-gain sound coming back at them through the headphones, they won't mind so much that you've got them running through a lower-gain sound because the vibe will still be there.
By the way, don't discount the Tubescreamer - it's sort of an Andy Sneap thing, using a TS9 as sort of a pre-EQ in front of a Rectifier, and I've heard of guys getting good results doing the same thing with a Marshall, too. The idea isn't to add gain as much as it is to mix up the harmonic content a little (something about even and odd harmonics, I forget), and to tighten up the bass a little bit. I don't come even CLOSE to diming the gain on my Rectoverb (2/3 at most), and I don't always use a boost (and when I do it's set for just the slightest extra grit and little to no percieved volume boost), but it is a pretty cool option (and, incidently, doubling tracks with a boost against tracks without sounds HUGE in ways I don't quite understand).
