Hi all, Newbie here looking for a little advice/possible light at the end of the tunnel. I have a set up which consists of: Boss>Compressor/Sustainer>BossOD3>BossDD3>Behringer Chorus>DOD Phase. (All ran by a Danelectro power pack)(Except Phase.) I have been running with this set up for over a year. Recently I changed amps and the Line 6 I am now using does not have a built in tuner so I got a Behringer stomp tuner, I took out the chorus from the power pack and put the tuner on my line. For about an hour it worked fine .then I got NOTHING. All of the pedals led lights are powering up but there is no sound. I have an old DOD Phase which works with a 9v battery on the line and this is working so I surmised that it was a power problem .then the realisation of POLARITY hit home and I checked the Behringer pedals are opposite from the Boss .but this only caused the problem when I put the Tuner onto the line it has worked OK whilst the chorus has been on the line My questions are have I fried all my pedals? How can I check? Please be kind with my stupidity I am relatively new to this stuff Cheers J.P.
