Hi, after a few long hours of use, turned on my DSL40CR and the sound faded away and now has a faint sound even cranked. Plugged in the the effects loop return and sounds fine so the issue is in the pream section. It's not q tube as o installed a fresh set to check and still the same issue. Any ideas what could have happened?
Hi Kevin,
Thank you for your comments, we would suggest the amp is looked at by an engineer.
