Peterson strobo plus

[Ronald Heinzel]

The last two times we played an outdoor gig my tuner would not work correctly, I get home and plug it in to the same gear it works perfectly. At first I thought the house music , coming through our PA on the stage that the heavy bass vibration was interfering with the tuner, last nite no house music nothing would register on the tuner, today no problem.
Anybody else had this problem ?

How are you powering it up?

I used a matchbox first then a steel driver the tuner was fully charged
