First post here but maybe I can help ya. I've got a spare #5, but dont know how richer the low end would be, if you have a 7 now. You could try it if you wanted.

I appreciate the offer. That would probably be, too rich. It wasn't a real need, just wanted to see if I could feel and hear a difference.
Try a richer diameter needle. It is the same effective tuning range as the cutaway, and much cheaper for experimentation. Needles on amazon are like 6 bucks. For instance if you are a dgj you would go dgh..
The cutaway comes in to affect, right after the pilot. And supposedly, through the mid-range. Wanted to try the #6. Your right, these slides new are pricey!
