Awesome info guys thanks a lot. Mr Hillside, if you have exactly the same setup as me, maybe you can help with my confusion as to how to hook this up. I do have a decimator I can use, just dont know where to put it. The gate in the fx loop calms my road king down very well, but this here setup is a different animal. The tone is killer, btw, you're correct. That's why I want to get this working so much.
Rd2, this hum parameter...I think I tried it to no avail, but would it really work anyway if I'm not using the Helix amp, instead goin with the rectifier?
Currently, I go into the Helix with the guitar, Helix send 1 to mesa Preamp input, fx send on mesa preamp to Helix return 1, and since the mesa preamp has 2 returns, I have them both hooked up to the 2 1/4 outs at the Helix. Finally, both mesa preamp live outs go to the 2:100 power amp. The mesa preamp gain is bout 9, and I'm boosting the front end with a Helix boost preset, so I know there's a lot to tame here, but does my hookup sound right? So far I've tried my Rocktron Hush twixt the fx send on the amp and the Helix return1. Also tried it between the Helix send1 to the rectifier preamp input, and both clip the sound way down.
I havent dl'ed the new firmware yet, but I will since it has that new gate, but I'm still lost as to how to get this hooked up. Thanks again guys
