having recently been bequeathed with a vs-840 from a gentleman who told the zip drive was a goner I have been trying to figured out how to harness unit as a headphone practice unit for my guitar. I downloaded a portion of the manual and it isn't clearly in there. I just want to plug in and play the COSMO models and presets. thanks for any help you can give me. I have gotten a sound from it...but it's a clean sound and doesn't change as I scroll through the presets. I'm a newbie with this unit...thanks again!
