I agree. If you're going to make an album, labour intensively over every bit of it. You may never get another chance. But you must also appreciate that most listeners won't appreciate the fact they you forked out for a £900 cab over a £300 cab. Of course, you can (probably) here it, and that's what is self indulgent. I'm not knocking it, everyone likes to self indulge.
As for stopping using pedals, I agree again. If they're pretty extreme, then they become an integral part of the sound. People will notice this.
They won't notice who manufacture your strings.
