Hi, I’m currently using a Helix alongside a Hughes and Kettner Grandmeister deluxe 40 as my preamp. So midi out of the helix changes presets on the hk. Guitar goes into helix out into hk via fx loop and returns back so I use the helix fx before and after the hk and cab modelling to foh. Problem is I sometimes get a strange momentary detuning when I switch from one snapshot to another on the helix. Like a tone down and then straight back up again. I’m wondering whether it’s the fx in the helix struggling to kick in and whether there’s anything I can do about it? It usually happens when I go between distorted sounds rather than clean. It’s not the hk and It’s playable but off putting. Any help appreciated. P.
