Stereo out question

[daveinspain]

I have an important gig coming up this coming Friday night at the best venue for live music in Valencia, Black Note... As Murphy's law dictates all of the sudden my Boss ME 50 is acting up. This is bad, I have all my custom patches and edits loaded in it's memory. First the Volume pedal was causing intermittent volume drops so I disabled it and patched in a Morley Volume Plus pedal. Problem solved... Now all of the sudden I'm getting complete cut outs, no sound at all... Narrowed it down to the Left (mono) output jack to the amp which is what I always use so I switched to the right output jack, seems fine now.

 

Question: I don't think there is any real difference using the left (mono) out put jack or the right one is there??? It's just that the left out is specifically labeled mono and the right out just says right...

 

Here's the Flyer for the gig...

Not good at all. I have Boss SE-50 and SE-70 which are the half-racks from the same era.

 

You could have a look at the LH socket to see if it is a dry joint but the trouble is that the outputs are hardwired onto the circuit board and you must have the correct replacement one. For the moment - if you are certain it is the left jack acting up - go into edit and adjust the L/R balance if possible. You may find that left is dry output + effect and that right is effect only. A Roland/Boss dealer may still be able to get this unit repaired if necessary; though discontinued, I believe they are still supported.

 

The other thing is that most Boss multifx have a lithium battery inside which powers the memory. You will know if this goes dead as you will lose all your patches and the display will show weird characters. Before this happens do a sysex dump to a music editor like Cubase on your computer.

 

Best wishes Dave!

In terms of the difference between left and right you might just want to check your effects like chorus and delay are still working properly. sometimes the main output sends out wet and dry signal whilst the other sends out a slightly different wet. A bit like say using ping pong delay or whatever

Yeah had it apart, looked at all the solder joints and reheated and added abit of solder to the ones that looked a bit iffy... I think it's the hadrwired jack itself that has worn out as that one doesn't snap in as snug as all the others do. Thanks for the heads up on the lithium battery, I'll back up my patches. Maybe I'll try swaping the left and right output jacks or swith it for the foot switch jack witch I never use.

[daveinspain]

Been doing some testing and so far all my patches sound OK coming out the right channel....

Swapping the out jack for the footswitch one is a good get-around, I wouldn't have thought of that. It should work for both.

Another thing I remember now about all Boss multifx - I also had a ME5 I think it was - you needed another footswitch connected to get all the options.

I ended up with a GT6, the gold metal case one; really incredible sounds but my life isn't long enough to program that thing properly....plus it was not just a multifx pedal but a preamp which changes the whole way you have to look at it.
