Without reopening the stompbox vs. rack gear debate, I'm looking for some opinions. I'm looking for an easy to see rack tuner that will grab my low B quickly and not jump around or suck my tone. The user reviews I've read on the Sabine products are so contradictory as to be useless. The few I have found on the Fender RT 1000 have been fairly complimentary. I really need some input from players who gig or practice with one. Any brand, good or bad. HELP!
