Cruisinon2, thanks! Yes, I only want to use the POD's effects with the head and use it's own preamp (no amp models). I've been trying some different level settings, but the tone/sound of the amp loses that full "open" tube amp tone with the 4 cm. I was hoping the 4cm would work, because it would be nice to be able to use the wah/volume in front.
It just might be the head itself - it's quirky with it's effects send/return levels. The manual says it's a -10db loop, yet in the next section it says that the individual channel volume settings will affect that level. It hates stomp boxes in the loop - overloads their inputs.....which (on paper, anyway) it shouldn't. That's why I've been using the rack unit with adjustable input/output levels and meters to show exactly where those levels are at.
Thanks again......back to experimenting for now.....
