Sorry if Iâ€™ve missed it but I canâ€™t find anything on this topic. I just bought a Mesa Mark V35 and currently own a HD500X (&dt25) my amp is supposed to be here next week. Iâ€™ve never worked with 4CM as Iâ€™ve only used L6 link with my setup and I keep reading about tone suck with the HD but also read how overcome that. Has anyone here gone from the HD using 4CM to the Helix? Is there a negligible difference that justifies buying the Helix for this purpose? Iâ€™m more concerned about the integrity of tone from that amp first and then high quality fx. Iâ€™m more focused on being able to switch channels on the amp and keep volumes under control without destroying the amps natural tone. Thanks!
