OK, I'm cleaning up the X-330 I just got and found this problem -- all electronics seem to work but the output from pickup(s) is weak when module NOT on -- only have the Power Overdrive module. The wiring looks to be unmodified. Good strong output with module engaged, very weak otherwise.....????

I would try disconnecting the 9 volt battery and removing the MPC module. Then try in each of the 5 positions on the 5 way switch and see if you get a volume drop. Also may want to clean the batwing switches. Hope this helps.

For Starters, I would apply some Deoxit (by Caig) to all the pots, MPC connectors and most importantly to the 5-way rotary pickup selector switch. This stuff did wonders to my X910 when I bought it, completely changed the way the neck pickup sounded for me. Could be something else, but those components are susceptible to corrosion. Good luck.

Oops, I think I have it backwards - removed battery and module as Arthur suggested and have strong output, also deoxitted 5 way, connectors, and pots --- maybe bad module ?? Which slot should module go in when using only one ?? Also, how do I clean the batwings - they look to be sealed switches - disassemble ??? Thanks, y'all !!!

Slot does not matter when using only one module, but as a troubleshooting step you should try it both slots. If there is a difference, the slot is the problem. If it behaves the same with the module in either slot, the module may have oxidation on the contacts, or it just might be bad.

The MPC bypass switches are not easy to clean. There is not really any access to the guts, so you can't really get the right chemicals on the contacts.

I would test with a known working module and if there is a problem with the switches I suggest replacing them. You could also try sending the module to have it tested by someone who has a known working guitar and other modules to compare with. Let me know if you would like to send it to me for testing.

This was the first one I had ever seen - each page can be downloaded to a folder -

It explains where and when to use the various modules / combinations, etc.

Great information -

Thanks for all the help -- after cleaning everything I think I found the main problem - the positive connector on the battery clip was very loose and not making good contact at all - I'm not getting the drop now, I think all is working - this is the first one I've had with a module, so I wasn't sure of the proper switch positions, now I can check that !!
