Is anyone experiencing noise issues with the new Pickup Booster? Mine generates noise with a Strat and a Les Paul. I've only had it for a couple of weeks and am currently running it on battery. My cables are fine and the booster is the only device connected between my guitar and amp. The amp is a Rivera Quiana (very quiet) with the gain rolled back a few notches. I saw in the blog section one user say his was unusable because of the hum and another say he was running it into a high-gain amp and his was silent.
