Hey Y'all, I can't find a Boss VF-1 manual out on the web to figure this out and I know a few folks here use/have used them so I thought I'd access the collective TB wisdom on this. This unit seems to fit my wants - 1/2 rack space, tuner & effects. I would be putting it in the effects loop on a Sansamp RBI. My main questions: - how do you select the tuner? Looking at what pics I can find of it there's no "tuner" button like on a Behringer V-amp. - does selecting the tuner mute the output? I hope so since this would let me drop it in and get effects & muted tuning out of the remaining open 1/2 space in my rack. - how well does the tuner work on bass (4-string for me)? - would the line input on the back work for dropping it in the RBI effects loop or would I have to run a cable out to the front guitar input? Thanks VF-1 gurus! And if you have any other words of wisdom to impart on these fire away. And if you have one for sale (Xyllion did you ever sell yours?) let me know what you want for it. Depending on the answers to my questions this could be my answer to removing another piece of gear (my pedalboard) from what I need to carry around. My bandmates are somewhat amused (particularly the drummer) by my drive to minimize what I need to cart around to play.
