Mini-Recto FX Loop hissing?!

[antikue]

Thanks guys, but it's not noise I hear - it's the preamp signal coming through. FX loop doesn't have a part in it, since the signal goes through whether the FX loop is engaged or not, or if I place a pedal there to cut the preamp volume. The signal is pretty loud on Modern mode, at a conversation level or thereabouts.

Got a reply from Mesa Boogie confirming, that the signal leak is indeed a feature of the amp. Too bad, as I quite enjoy the tone. A PPIMV wouldn't hurt I suppose
