Hey sorry for the late reply. Although the RC was hooked up, i had it on bypass to bypass attenuation. I just used the fx loop return master to let me get a bit of channel master volume in 11 o clock range without blasting the walls off. So fx loop trick i guess ? lol
If you look at my other vids on the youtube channel, Wizard MTL and MC II, the Helios is amazing and only thing it doesn't do is a bit more modern sounding tones that the MTL does or MC II similar reign.
