Even if you're recording them DI, I think you will get better results with your gear.
I've heard the arguments that professionals are recording the amps, you'll get the use of their studio, blah blah. But if we pair a nice cab with a great DI you recorded yourself (I know a lot of guys do this with any profile they use, swap out the cab), I believe you will get better results than you think.
For example, I find a lot of the bass profiles on the rig exchange are nice, but when I run my bass through them, they're too boomy, too hi-fi, etc.
Today, I ran my bass through a Darkglass amp and wow! Being able to tailor things to my instrument is amazing.
I was able to reduce the boom in the bass, get some nice grit and grind to the low and hi-mids, tame the clank in my bass, and adjust the amount of distortion that was being fed by active pickups.
The Kemper controls are great, but not like sculpting your sound on the real amp. For example, when it comes to boom on the low string, I find a simple bass high pass filter kills some of the punch. You're also stuck with the distortion and EQ settings decided by someone else.
It really was eye-opening to do this with a bass. The argument against creating one's own profiles has always been pitched to me in terms of the negatives of my setup.
In that regard, I think I'll get myself a DI and do some recordings of my guitars amps for myself now and then try pairing them with some cabs made by others as well, I have a feeling I will be really happy with the results.
Waiting for the counter rant, gents!
