You've got two inputs on the DP-02 so you can record two sources at once.

Depending on how you want the electric guitar recorded (mic the amp, or direct line in) you can in the first case plug your guitar mic into one of the mic inputs on DP02 and plug your vocal mic into the other mic input. You also have the option of plugging the guitar directly into the DP02 (using the hi-z input - I believe it is labelled 'guitar' or something on the DP02. I any event I believe it's the one on the left). This way you only need one mic for use recording the vocal part.

To avoid any 'bleed' between channels you can use the headphones while recording this way and you'll avoid having the unamplified guitar sound coming through over the vocal mic.

Once you have the mics or guitar and mic plugged into two inputs, you need to assign the inputs to a channel (track) to record on. You do this by pressing the select button for the input and then pressing the select button for the track where you want to record the input. Do this for both inputs so that they are recording on different tracks. Then arm the tracks for recording by pressing the record button for each track and the lighted buttons will flash above each armed track. Then just press play and record and you'll be recording. You can go back and redo it as many times as you like and record over what is there, or preserve a take and assign a new track (or tracks) for another take. You've got 8 to play with.

Hope this helps.
