    Switching this amp to standby (down) will produce an annoying “pop.” I have also read the article that Sweetwater has on their site explaining why this is “normal.” I have also read that Fender has warned that fixing it would void the warranty.

    Nevertheless, it is annoying and I would like to fix it. Has anyone out there successfully fixed it? If so, how?

    Thank you.

    I think my old Bassman used to do that, although I'm not sure I remember.

    It might be a vintage feature.

    I looked at the switch in my DRRI and it is encased in plastic. It would be possible to add a capacitor to stop the pop, but not worth it to me. It is a Fender thing and I put up with it on the other Fenders I owned.

    What you are doing is interrupting the flow of dc current. The current through the output transformer abruptly stopping will cause an audible output. Just the way things work. I would just use the switch as a mute instead, or just turn down the volume control.

    AFAIK, standby is useful when turning on your amp, but needless for muting it. Just turn down the volume knob.

    +1 on this one. IMO Standby should be used only when turning on the amp. If you want to mute it, turn the volume down or mute it with the tuner pedal.

    When turning off the amp, only turn off the main switch. Before you turn it on next time, flick the standby to off first. It's a bit of a dance but that's the way to do it.

    I have successfully fixed such problems by installing a .01uf, 1KV ceramic capacitor across the standby switch contacts. It eliminates the internal arcing which causes the pop.

    I've got the same problem with a Carr amp I have. Doesn't do it all the time, never can tell when it will or when it won't. Contacted Carr directly and was told "this model pops more than others in our line. Won't hurt anything at all, but if it bothers you, just turn the volume down before you switch the amp off".

    Good enough for me.

    EDIT TO ADD: FWIW, the Carr amp I have has a single throw/double pole switch, not two separate single throw/single pole switches like a DRRI has.

    I always turn an amp up after I've turned it on and turned it down before I switch it off.

    Never hear no pops babay!

    My Pro Junior III does it especially in this season however if I touch the plastic handle
    while turning the switch off (same hand) it doesn't pop. I suspect static buildup.
    My Classic 20 though pops no matter on turn off unless I put a headphone plug partially in which
    only mutes the pop.

    my twin reverb does the same. I asked about it (here?) and learned it’s totally normal and harmless.
