I have been experiencing cell phone interference with both of my Barber Tone Presses (an older one and the compact version) and was wondering if anyone else has had this problem. A search shows that there has been reference to it in the past but nothing recently. None of the other pedals on my board have this issue and both Tone Presses do it either by them selves or on the board with other pedals. I've tried different power supplies, amps, etc. I've also tried keeping phones at a distance but at gigs I still get the noise from patrons' phones. My Keeley 4-knob gets a tiny bit of interference if I set the phone right on top of it, but the Tone Press can detect a phone from quite a distance. For now, I am using my Maxon CP 101, which I like a lot, but I still miss the Tone Press parallel magic.
