JMP-1 preamp owners

[peterc52]

Just bought one!

There's a audible hum from the tranny, is that normal?

It's kinda annoying me since I use in a studio.

I dont recall that on mine, but honestly its been awhile. bump for someone who might still have one with an opinion?

no audible hum in mine.....
i have owned two and they were silent.

Some guitars on mine have the hum others don't. I've found plugging it in different buildings affect it, at my rehearsal studio it screams it's tits off but in the house it's fine!

one of my best friends uses one, and I've filled in with them several times. Never heard any hum coming from his.
