I know there are lots of threads about using the 4CM with tube amps but I couldn't really find what I was looking for, so, here goes another one. The idea is this, I have a marshall JCM 2000 DSL100, I want to use my marshall's preamp for distortion and the pod hd500x's preamp for my clean sounds. I'm connecting my guitar to the pod's guitar input, the pod's main output to my amp's fx retunr, my amp's fx send to the pod's fx return, and the pod's fx send to my amp's input. For my dirty tone I basically created a pach with basically a noise gate, a wah, and a tube screamer, I leave the amp block empty and after the mixer I put the "FX loop" block and after that a delay and a reverb. For my clean channel, I put the Fx block at the very start of the signal chain, after that, a chorus, phaser, a fender amp (without the cab sim) and after the mixer, delays, reverb, etc. So, my first problem is that while I was testing this configuration today, I realized that the "clean" tone sounded a lot louder than the dirty channel, my amp's preamp (btw, I also noticed that after putting the pod in the signal chain there's a general volume drop in the amp, but I don't mind as long as it sounds right) so, the things is, I can lower the clean amp (pod's amp simulation) but when I do, it affects the amp's simulation tone, If I lower the master volume, my dirty channel loses input so it lowers the distortion, so: 1 - What would be the best way to approach this problem and get balanced levels without affecting the tone too much? 2 - Is the order I place the effects (for both the dirty and the clean patches)correct or is there a more recommendable way to do it? 3 - Also, in the back of my amp, there's a loop level switch (-10/+4 effects) where should I leave it? 4 - If I'm not using any external effects, should I set my pod's out to stomp or line level? because for me it makes sense to leave it at "line" but I've read a few topics where people recommended to leave it at stomp with amps and stuff like that anyway. Thanks! :)
