So i'm trying to decide which will be better for my live playing, a rack mount tuner or a pedal tuner. I've got the space in my rack for one but i don't have much experience with them. I want something that i can use to tune down half steps and will mute while tuning. I've been looking at like the Korg DTR 1000 or 2000 rackmounts or the Korg DT-10 foot pedal. Any opinions?
