Dear Friends, i found another post regarding this issue, but i did not find a solution. I use my Hd500 ONLY for effects with my peavey 5150 combo. I have just placed in the 4 CM the input 1 to guitar and input 2 to variax. I have just muted path "B" and placed path "A" panned to centre. When I place an analog chorus between FX Loop and Mixer, and I switch it on, the volume slightly increases, and this is a little frustrating when I play Live. Is there a solution? My firmware is the latest version.

After this I would like to talk about the HD500 in general. In this forum there are TONS and TONS and then TONS of discussions related to signal level adjustments here and there, Fx loop level drop, mixer db adjustments or Studio Eq to place for signal matching etc etc, while many people say (and It's true) that a M13 has not this levels issues at all and is more "plug and play". So my question is: What the hell is this? Why Line6 Engineers have not planned a "transparent" setup for this unit for using it like a normal M13? I like to play guitar, but since I've bought this unit, i find myself trying to setup the levels ALL the time and I don't like it. I think many users here have the same problem. This is frustrating. Many players here use 4CM with their amp and obviously use a MONO setup. But we have dual inputs, dual outputs, many stereo effects, and there is NO clear instructions of How to setup them properly, just tons of posts of users that are in my opinion "BETA TESTERS" and looks for a solution. I would like to see a manual in which there's written: "if you wanna have that kind of setup here are the settings", but written from line6, not from users. On the other hand, if you play studio direct an use mod amps, this is a great unit, but I'm not interested in it. I apologize for this post, I just would like to place my opinion.
