Lots talk here. I have to look at directions again but I think you hold one of buttons on power up.It does? How does that work, exactly. Cause this is news to me, and good news at that!
At the front of the chain I'd need four — one in front of each EQ. Which means a bigger board. Which might mean a new power supply.+1 for the Polytune. It has a really great buffer, which is good to have at the front of your chain if you use more than a couple of pedals. And of course, you can turn off the buffer if you don't. Plus the strobe mode is really nice.
