There are a few ways a tuner pedal can be hooked up to a pedal board. Via a A/B box or Looper, so it is bypassed when using the pedals Using a tuner out on a volume pedal Using one of the stereo outs on one of your pedals Run the signal through the tuner pedal at all times I'm sure there are other ways too. What way do you use your tuner pedal? I am getting a Korg DT10 and since it has a good buffer, I am leaning towards running the signal through it (as in #4) just for simplicity, hoping it won't degrade the signal too much. Thoughts?
