Dude? Those have their own forum... it's like... racism.
I have one and I absolutely love it. I just bought an Ovation Elite LX with the OP-Pro preamp and I use the ceramic pezio (#4) setting for the preamp neutralization. I haven't checked out all of the 256 possible settings yet but everything I have tried off of #4 has sounded killer through my ProTools rig. The rosewood settings sound very Martin and the resonator setting is very cool as well.
It is probably one of the slickest pieces of gear that I have aquired in a long time.
Nice! I've thought about getting one considering that OP Pro preamp is decent, but not amazing.
I don't have any issues with the OP-Pro preamp and it sounds as good as the CoolTube preamp that was in my Tak or any of the other guitars I have tried receintly. Mostly the issue is with mics and preamps being able to correctly translate what happens inside an acoustic to make it sound like what you hear on the outside. The Momma bear normalizes that signal and with filters and digital modeling adds all the stuff that is missing back into the signal. It's a weak explanation and Rick is a better person to explain it but that is my understanding.
Whatever it does, it makes my recorded acoustic tones sound phenominal and offers many different and completely believable tones from one acoustic guitar.
Very cool. I'm surprised that Cool Tube preamp didn't sound better than the OP Pro too (those always looked pretty cool - I was thinking about picking up one of the higher end Takamines). Looks like I'll have to put that on my wish list.
robert, how wet do you runs yours? .. i really prefer mine run darn near 100% wet ... it knocks out all the quack from the piezo bridge of my RMC bridge in the brian moore solid body electric ...
