DSL 50 Problem ... Effects Loop ?

tunetaylor1 · 02-03-2009, 06:35 AM

Troubleshooting help??

I have a MXR EQ and a memory man in my effect loop..... TU-2, Wah, Keeley/Boss SD-1 in front....
Two days ago I was jamming and decided to see what effect the effects loop pad button had on the sound... No big difference.... but 5 minutes later my sound slowly died, (sounded like a battery dying on a pedal).... I checked all the connections and the power snake inputs (no batteries), and nothing fixed the problem. I flupped the power to standby and back on.... it worked fine for another 2 minutes.... then died again....

Next I plugged direct into the amp and pulled the effects loop out.... worked fine...

So last night I hooked up all the effects, as they were, but pushed the loop pad button back in and had no problems after 1/2 hour...????

Would the loop level cause this to happen??? Do I have a problem with my Head??? I only have another week left on my 30 day warranty..
If there is an issue I have to find out soon?

I guess I should try to duplicate the problem again... Maybe I will take out all the effects in front try to get it to cut out again with the pad button out..
I don't think this will hurt anything???

Does anybody have any experience with this problem?
Any suggestions??

thanks,

Hi,

I had this often on my old JCM900 - if I had the setting wrong when I switched on then there would be some loss in volume or something would not be right - mostly I had to switch it off (power cable out) to remedy this. I know this is not right but for some reason it did get confused.

The DSL is slightly different but is also sensitive - we had a similar posting here recently - I do not notice much difference (in or out) so I always leave the pad out (for normal instrument levels) and select the 'instrument' imdepence on my fx-unit to match. I know this is the right option so in other words I gave up.

Setup everything like I do and it will be ok.

Cheers Brett

Another suggestion- if you want to do some testing to be 100% sure the problem is in the FX loop/button, just take a known good patch cable & run it from the send to return in the loop without any pedals/fx. That will also give you a feel for the coloration the loop does to your tone.

I hated the loop in my DSL 100, it was very noisy and sucked tone; had Voodoo swap out the chip in the loop and it is like night & day difference, almost no noise, and the tone now sounds unchanged.

I have the same problem with my DSL50.

Do you have any info on the chip Voodoo put in?

Was it stock or an upgrade?

I wonder how big of a job it is to put it in yourself or have a local tech swap it out.. I was on the voodoo site and haven't seen this mod.... I don't think??

I am definitely going to try that patch cable suggestion....
I played tonight but only on the original set up - I didn't try to reproduce the problem again with the level button out... working fine...
