Hi Michele – I’m also having hum issues. I usually run the H9 mono to an AC30’s instument input via a Framptone amp switcher with the second out put going dry to a jtm45 – have had zero noise issues like that but, thought I’d try going stereo – this is where the hum comes in & only affects the jtm45 (I have 2 overdirves/boosts into a keeley compressor into the framptone) I swapped outputs to see if the hum travelled to the ac30 but it stays with the jtm45. There’s a ground lift on the framptone ut it makes no difference. If anyone has any ideas please let us know.

Thank you.
