Mailist to discuss all issues regarding the Digitech GSP-2101 Guitar FX Processor

My 2101 stopped working.  Removing the cover revealed a white wire
leading from the front input jack,  but not connected to anything I am
sure this is the culprit.  Could someone take a decent digital
photogrph of the inside of there 2101 for me?

Thanks!

Thanks Graham,

I couldn't see in enough detail so I posted shots oh my troubled 2101.

There are in a directory in the photo section called: White Wire
Disconnected.  here is the URL:

If anyone out there can tell me where this wire should be connected
that would be great,

I'll try and open up one of mine tomorrow.  In the meantime I wouldn't 
fire that thing up since that wire appears to be coming from the Mains 
and could do some harm if not properly connected.

that would be great if you could help out with some images and
descript of what you see in yours.  


Thanks,

Hi Mike,

That is definitely the culprit...it is the "live" from the mains to 
the PC board before going to the zero ohms resistor then to the step 
down transformer for the 2101.
The connector has broke off from your 2101 PC board, it should be on 
the board marked as "QT1".Do not attempt to turn it on before 
repairingthe unit as if the exposed part comes in contact with the 
body of the unit you might see some sparks flying around or worst you 
could get electrocuted.

I have added a photo to the album you uploaded here in this Board of 
where the wire should be.So check it out and good luck.Btw if you are 
well in soldering parts its a fast repair DIY.

Mike if it would help I can send you the schematics just e-mail me directly.

here is a diagnosis I received from Dieter after viewing the images:

There are more than 2 problems in your unit!
1. The white wire must be mounted on the left small PCB where the
power switch is soldered.
There was a lug, at position QT1. It is broken away. So solder the
wire to the solder via "QT1".
2. The transformer is loose. fasten it with a screw and a nut!
3. Resistor R522 is blown! its a 10 ohms 1/4 watt carbon film. If you
would replace it, it will probably blow again. Before you replace it
you'll need to remove the defective part in the +-12V circurity. It
can be many parts so you have to measure.
