OK...a little late, but here goes...
I have a Rogue, an Excel, and a Series II. For the Rogue and Excel, I switch the battery everytime I lemon oil the fretboard (every 6 months) I run the series with the DS5-R, but tune with the 1/4-inch. Now, my 1/4-inch was made with a mono-stereo switch, so I can play it through headphones, or with a standard guitar cord. I didn't specifically request it, it just came that way. FWIW, I have yet to change my Series' battery after 2 months of tuning...
