OK, I'm actually quite surprised at how good the redwirez are. I've used a few different brands of IR's and I have to say the ability to mix multiple IR's together to get the exact sound you like is actually pretty amazing. I've actually achieved the sound I like in less time than it takes to dial-in all the different components, EQ's, compressors etc. to get it to where you want it inside helix. I think I have less components in my signal chain now. I also like the fact that you can use it as a channel strip plug in and record directly with the highest quality IR's in logic. My recordings sound crystal clear I'm super impressed. Then once you get the combination of IR's that you like you can mix it down to a final IR export it and imported back into the helix to take with you. Absolutely love it.
Thanks for the review OP it made me go out and get the whole big box today.
