Gt-1000 - loop 2 is usually at the front of every chain. I use this to downtime the guitar and occasionally use the divebomb ability of the DT. Loop 1 is usually placed after the amps, but occasionally before, and contains a ms70 CDR that's usually set to a ducking delay, and the ms60b that works as a boost or can cycle between a lot of bass drives and effects that are mainly used in front of amps in bass patches, but occasionally to use with guitar rigs too. I find the HR's distortion models to be limited, so the Digitech gives me a lot of dirt options, the bass overdrive gives a bass specific distortion (that can sound surprisingly good with a guitar sometimes too), and nothing beats a nice tube screamer, and the green Behringer is faithful to a real one at a fraction of the price. The echo machine gives a great ducking delay.
