bumping this
I just had Greg make me a custom impulse and I have to say its one of the best investments I have made. The reason why it works so much better than just using s-preshigh or some other impulse is because those impulses aren't made for your specific guitar or style of mixing. Greg made me and impulse and found a tone based on my DI's and backing tracks. Not only does this create an impulse that best suits my guitar and pups, it also creates an impulse based on the clarity and style of my specific mixing.
Also, when Greg sent me my impulse not only did he work quick and effectively AND send me multiple positions of that impulse, he also gave me a few tips on how to process my guitars within the context of the impulse and mix. These impulses honestly can't be beat. They are incredible clear, punchy and they are everything that I could want.
Thanks again Greg!
