I'm no longer ISO for the RL PMB-1 or 2; found one, plus a DTAR Solstice, so my 'backup bevy' of blending preamps search is a fait accompli, thanks. ;-) ~~~ I use a Troll ribbon mic coupled with a piezo bridge pickup, to amplify my double bass with fine acoustic accuracy. My preamp is a Raven Labs PMB-1 Blender, mixing two signals to output singly into my WW MI 100-8 amplifier rig, or the house PA. Earlier this year at a festival gig, my PMB unfortunately hit the stage floor, which toasted the master volume pot. It's now fully repaired and again working fine, although this got me thinking: I really must find another one of these for emergency backup purposes. (Yes, the Grace Felix is a nice alternative, but for me not really a viable one given its ridiculous landed retail cost of >$1000.) So...ISO (in search of) a fully functional PMB, for a reasonable price. Thanks for any leads you might have! :-].
