Wow, it just keeps going! I guess maybe I started it?
The fact is that we're all kinda just talking generalities and debating philosophy, but not really helping the OP any. Maybe that's why he hasn't come back?
But really, that's the big issue in this thread, and something I tried to point out way back in my first post. We know absolutely fucking nothing about this situation except that some dude with 7 posts wants to record some "guy who plays guitar" and he (the OP) is unhappy with the sound coming out of the amp.
Is there a band involved, or is it solo guitar? Is anybody getting paid, or expecting to get paid? Is this intended for commercial release, a demo to shop around (for "deals" or gigs), or just a vanity project? Exactly what is the relationship between the OP and the "guy"? Are we just buddies fucking around? Did he get your name off your craigslist posting? Has he come asking you to help him refine and/or define his sound, or is he just there because you have better gear and/or space?
In short, WTF'n'F are we talking about here? Depending on whether I'm logged in or not it's either 3 or 10 pages of Greg (and I, I guess) arguing against RAMI and miro. Par for the course around this place, I suppose...
All of the above-listed situations are perfectly normal and valid, and it is by no means an exhaustive list, but each demands a slightly different set of skills and/or attitude from the OP. All of this should have been ironed out in "pre-production" talks. Before the time/space was "booked" there should have been some discussion on the intentions of the project, and the various expectations that each party had of the other.
I for one did not intend to imply that it is just completely wrong to try to offer opinions, advice, or experience when and where it is appropriate. I just wanted to point out that maybe it wasn't really appropriate in this case, or possibly even just a waste of time and energy.
If it's just a vanity thing that nobody's going to hear but the "guy who plays guitar", then why the fuck would you do more than maybe say "That sounds kinda funny to me, maybe we could try..." and when he says "Nope, this is what I want" you just shrug and go with it? Then don't put it on your "demo reel" if you don't want people to associate it with your good name. Dude might eventually decide that it does, in fact, suck. And he will also remember that you told him it sucked, and offered options, and that he rejected your suggestions. Unless he's a real prick there's no way he can stick that on you.
Or you could insist that he change his preferred way of working and present him with something of which you can be proud, and he'll cringe and bristle every time he hears it. Any time he plays it for a friend or family member he'll say "It's not exactly what I wanted, but the engineer just wouldn't listen to me."
I don't know. We kind of got away from helping the OP come up with options. Partly my fault, I suppose. I just wanted to point out that one option - definitely easiest, and possibly best depending on the situation of which we know nothing - could be to just record what the client asked for.
