Bugera 6262 Infinium

I received the 6262 head & instantly noticed that the high gain (lead channel) didn't have that much gain even with the lead chan gain knob maxed out - bizarrely I noticed that the turning gain knob on the **clean channel** added more gain to the lead channel... this means that the clean channel is no longer pristine clean when i switched channels from lead to clean... pretty unusable & very disappointing so I have had to return the head & am currently waiting (end of June 2020) for a fully functioning replacement. Its a pity - because the tones from the amp sound awesome. Hopefully its an issue unique to my specific amp, and not a bug in the 6262 models in general...
