Digitech DIGITECH GSP5 Manual

Read your manuals for both pieces of gear carefully first. You only have one amp so you won't be able to take advantage of all the FX on the Digitech as a lot of them are designed for stereo. The Digitech manual shows guitar into the Digitech and output from the Digitech into input of any guitar amp. Since you have a Marshall and can already get some great sounds by running your guitar straight into the Marshalls input, you would probably be better off using your Digitech in the FX loop. Run a guitar cord out of the send on the loop into the input of the Digitech and a guitar cord out of the left / mono output jack on the Digitech into the effects return jack on the Marshall. Start out with the effects level on the Marshall all the way down. Do the same with the Digitech with both the input and output levels. (Read the manual carefully) I think the choice of the Digitech isn't that great because it is already trying to reproduce a lot of what you can already get with just your Marshall but with a little experimentation and some careful adjustments you should be able to add to the sound of the Marshall. Hope this helps.
