I'm not sure I have such a fine tuned ear to get it dialed in and I'm afraid to spend all the money on Wally's shop and then wait a year to get it. The fozgometer might be a good option but I've heard it's not super exact. I might try to listen in, what would I be listening for? Also are there any filters other than Wallys that do the same thing? I'd like to do it mathematically and just be done with it.
