I don't honestly think that using an arranger is much of an improvement over using great players..!
I've been playing and recording a bit recently with a guy who played for years with James Taylor, Jackson Brown, Bonnie Raitt and many others. The day an arranger can play 1/100th as well as he does, I will pay any amount of money for it! Same with drummers (my last one was with Asleep At The Wheel for years - got a Grammy!), same with horn players, etc., etc..
Look, I'm not putting home studios down... plenty of good stuff can come out of them. I do orchestration work out of mine that sells six figures a year (for a client, sadly!
). But getting people to realize that maybe they are messing up a good thing with a terrible recording can be difficult. And no, they don't have to rectify it by paying $1500/hr and hiring the Saturday Night Live band to play on it! But something in the middle can go a long way towards achieving what they want to do. Few here are pitching songs to Nashville (are you?). Most just want to make a decent quality CD to sell on the gig (like your wife).
But telling everyone that, with a T3 and a decent mike, it is all going to happen ain't always true. You can teach a guy to fish, and he can STILL get skunked every time! Or he can go to Captain D's, or even an upscale fish restaurant, and get fish any time he wants it. Learning the studio techniques to even get a passable demo can take many, many frustrating months or even years. Few here have even the patience to learn to PLAY, yet alone work a studio (you catch my drift?) to an acceptable level (to even themselves).
I heard the one thing you posted recently, which you said was done quite a while ago... Have you anything more recent, arranger-based, that utilizes your improved recording skills? I would love to hear it. Honestly. You've got a great voice, and I'd like to hear how you've come along in the home studio. We can talk all night, but a song say a thousand words.
But, bottom line... Professional production has it's place. Not everyone needs it, not everyone DOESN'T.
