Constant noise from the speaker Check Basecamp for updates

I’m hearing constant hum/hiss/white/fuzz/crackling noise in my Spark

• Verify if PSU is grounded -> If not, resend grounded PSU (Regular PSU requests - Check Basecamp for updates)
• If PSU is grounded, the noise is the white noise caused by defective component (video is helpful) -> RMA

- Special Case:

If the amp is out-of-warranty and there is no guitar sound from the main out, only white noise, please ask the customer to provide a clear photo of the serial number.

Check if the 7th digit is 9 or 0: S040C59Axxxxx, S040C902xxxxx, and S040C90Cxxxxx

It means the amp was manufactured in 2019 & 2020

In this case, we'll assist the customer to return/exchange the amp (PG paid).

Provide the Information if it's necessary:
