WD-40 do make their own brand of contact cleaner… ![Screenshot 2025-07-13 at 15.00.01](https://us1.discourse-cdn.com/flex020/uploads/neuraldsp/original/2X/3/34a7869d27d4e4dbb1644cdff61f6b89ccbef1c6.jpeg) ---

Well, lookie there. I had no Idea. Hopefully it’s not their old penetrating lubricant in a different can. 😁 ---

I am definitely going to try your solution. I ordered the WD-40 Specialist Contact Cleaner Spray but I have 2 shows before it arrives. Do you think this might do the trick in the mean time? It’s CRC Contact Cleaner. Thanks! ![Screenshot 2025-07-13 at 14.05.06](https://us1.discourse-cdn.com/flex020/uploads/neuraldsp/original/2X/c/c400519b956684bb2cee1596d82390db8f1330bf.png) ---

I used this:-) Kure has CRC 5-56 and it is similar to WD40, well…not for I/O. ![image](https://us1.discourse-cdn.com/flex020/uploads/neuraldsp/original/2X/7/7660316267fb4c9d291375c4f66a86b425977583.jpeg) ---

Mine did it again last night before a show, I turned off and on again 2 times and the last time worked. Sometimes the Db meter reading is frozen, but sometimes they read the input ok, though there’s no sound coming out of the quad. ---

Yeah i have this issue regularly. Its extremely frustrating. I wish NDSP would acknowledge it and hopefully its a software fix… ---

I solved this by spraying the connections on the Quad regularly with CRC Contact Cleaner. Hasn’t been an issues since. I think that area gathers a lot of _party gravy_ during gigs and needs to be kept clean. ---

This may sound strange but every so often I’ll turn it on and there’s no sound on a certain preset and I will remove maybe a compressor app and it starts working or the other app that seems to affect it is the internal app for external Pedals if I don’t have a pedal plugged in to die it’s not always going to it most of the time it does, but sometimes I will move it and the sound comes on.
