Jean-Luc Pickguard Posted October 31 Share Posted October 31 I recently found my EHX bassballs and Morley sync attack effects which I'd not seen for decades. I'm hoping my 70s coloursound tone bender will turn up as well, but I might have left it somewhere or gave it away back in the distant past. The Sync attack was an easy fix and is now fully working once I'd rigged up a working metal pick to trigger the effect, but the Bass Balls seems to be dead when tested with a 9v battery. It looks like I, or someone else was in there previously with a soldering iron as there appears to be a non-original pink wire. Does anyone know about these or own an similar 70s example of this pedal they can compare with mine to see if I have any wires missing or incorrectly connected?

Jean-Luc Pickguard Posted October 31 Author Share Posted October 31 (edited) Thank you — that is a great help. It looks like we have the same version of the circuit board and on initial inspection the wires on mine look like they're all present and connected the same as yours, albeit with some colour differences. One area of interest is the power socket. I was wondering about mine as I can't see it clearly, but I can see from yours that theres a pair of elements that appear to act as a switch to cut off the battery when a psu's mini-jack is plugged in. I wonder whether my issue could be as simple as the two bits on mine that make up the switching part of the socket either not making contact or in need a clean. I will take a closer look and have a poke about with the multimeter. Edited October 31 by Jean-Luc Pickguard 1 Quote Link to comment Share on other sites More sharing options...

Could you try powering it with a power supply rather than a battery? Quote Link to comment Share on other sites More sharing options...
Jean-Luc Pickguard Posted November 1 Author Share Posted November 1 I don’t have a PSU with a mini jack so I can’t try that. I have replaced the battery clip as the original one was corroded from a leaky battery and wasn’t making the multimeter beep in a continuity test. I put a clip over the switching part of the power socket and tested the pedal but it is still not working. Will have to try some more in-depth investigations.
