Marshall Mosfet Lead 100 boost channel pop

[jjonas2]

Hi,

I have a Marshall Mosfet Lead 100 guitar amp (3210), and when I switch to the boost channel while playing, there's an audible pop (also if connected directly to a mixer from the DI in the back). The other way (boost->normal) there's no pop if I switch while playing. Also, normal->boost there's no pop if I'm not playing.

What I want to ask is, is this expected behaviour?

Without hearing it, I'm going to say that it is most likely normal for this to happen.  Channel switching can certainly cause noises on certain amps.
