Hey. If you got a POD HD500X, i have found it to work well with the beat buddy drum machine. Using the midi sync cable to sync the beatbuddy's tempo to your Pod makes looping easy. But the tricky bit is recording the guitar and the drums together.
This is what i used "5 Pin DIN Female"plus a Roland UM-ONE MK2 USB MIDI Interface.
And setting it all up is easy, and easy to get the midi drumbeats to work too ;)
