I am the happy owner of a POD HD500 and I am soon to receive a brand new Blackstar HT-5R. I want a take advantage of its effects loop so I have been trying to figure out the 4CM method.

To me it is clear what to do if I want for an specific effect to go before or after the Blackstar's preamp. However, I would like to use the POD's preamps and avoid any coloring by HT-5R's pre amp. So the question for you guys is:

Can I bypass the HT-5R pre amp in any way?

PS: For the uninitiated, there is already a great deal of excellent information in the forum regarding the Four Cable Method. An example is the following link: http://line6.com/support/docs/DOC-2504
