just wanted to chime in with my experience. i just purchased the mesa 1 cab from ownhammer.. and after extensive testing an a/b ing i gotta say i like the ownhammer impulses just as much if not slightly more than the redwirez at this stage. i feel the tones are slightly more usable in a mix, they are just clearer and more balanced. i will say though that the redwirez do feel a smidge more 'real' or dynamic in some way, but for metal at least i think the ownhammer is a better buy. great product and i really enjoyed the ease of use
