FrankLake Posted January 9, 2020 Share Posted January 9, 2020 My DL4 has developed a strange issue on the ping pong setting only. It sounds like the repeats have a super saturated wow/flutter/trem distortion sort of sound on them. I've cleaned all the pots and switches, all solder joints seem fine. could it be the firmware eprom? It's very strange that every other setting is working perfectly. Cheers.

doublebreaker Posted February 23, 2020 Share Posted February 23, 2020 Hello, I had the same problem with my Dl4. I checked the solder joints under the eprom-chip. One of them looked strange and I soldered it new. Then the ping pong worked. Hope it will helps. Best Regards Quote Link to comment Share on other sites More sharing options...
reallyokman Posted July 11, 2023 Share Posted July 11, 2023 Did you ever repair the issue? Same thing happening to me. I have yet to open the board up to check for bad solder joints, will be doing this later today. Quote Link to comment Share on other sites More sharing options...
