Help, that's what happened to my Boss TU-2

Hi all,

I'm here seeking help, maybe some of you experienced the same!

I have a Boss tuner TU-2 (the pedal) as the entry of a effect chain in front of the amp. The other day I was playing and all of a sudden I lost all sound and I then I heard for a few seconds weird distorted low frequency sound as I was trying to play to see what was going on... it took a minute to figure out my bass batteries were dying... I tried to put the bass directly into the amp but no more sound out of the instrument.

I replaced the batteries, plugged directly into amp and bingo, I was back. As I tried though to go back to the pedal chain no sound any longer. I made some test and it's the Boss pedal, it still works when in tuning mode, but switching to normal playing doesn't work, also the bypass option doesn't work... I opened the pedal and nothing seems strange ( I mean, I'm not an electronic expert but nothing was obvious like desoldered join or whatsoever...)

I cannot explain myself what could have happened, maybe the distorted signal burned some circuit???

Anybody has any idea what could be going on here?

Please...

Thanks, Paolo

How are you powering the TU2? Distorted audio could not burn out the circuit, but I wonder if somehow the batteries in the bass discharged a massive DC power spike? I've never heard of it happening, but it's also strange for the bass to go silent so suddenly. Usually a dying battery will cause distortion and a weak signal for several minutes at least while the battery runs down slowly.

TU-2's do some weird things when the batteries start to die (in the pedal, not your bass).

I think that might be it... for whatever reason the guitarist of my band thought it was a good idea to unplug my Trex which feeds power to my pedal chain. The effects were running on batteries and all were ok except my tuner which had enough power only to keep tuner working but was cutting the signal...

at least that's what I think it happened... today I founf the Trex unplugged and by plugging in again evertyhing was working... I feel so stupid having asked help for this !!! sorry!
