Phil,
I have a free impulse in the beginning of this thread that you are more than welcome to download and use at your will. You may also compare it to whatever other impulse you would like. Several people on this forum who do great work have used my free impulse as part of their guitar chain (Dandelium, Jaymz, 006, Kyle Odell, etc) and obviously preferred it for certain applications.
I have done more custom impulse jobs than I can remember since I started this whole thing, and there is a reason I keep getting more work. I don't find it necessary to make direct comparisons to anyone else's impulses publicly, because a. there is an obvious bias, and b. it would be easy for anyone to "rig" their impulse in a test to come out sounding ahead. What it comes down to, is that I create impulses based upon the a guitarist's needs, and it then becomes part of their "sound." No one else has access to your impulse, unless YOU want to distribute it, and that's what it comes down to.
If you are a fan of the reamping work I do, there's a huge chance you'll benefit from having a custom impulse, and if you're tired of hearing the same guitar tone character over and over, you would also be a good candidate. Ryan's impulse is definitely a great sounding one, much better than 95% of the stuff out there, but you have to come to your own decision whether you want one of mine or not. You can ask anyone who has worked with me that their experience has been more than pleasant, and that the turnaround time for my work is quite above average.
