I picked up a BR-180 and had a LR Baggs Anthem installed--and yes it does BOOM. The secret of course is in EQ. Since the Anthem doesn't really have an EQ--just volume and mix between microphone and transducer--you need to EQ it somewhere.
I use A MXR 10 band EQ right on my acoustic pedal board. It works better than anything I have ever tried--the bad news is it uses an 18v wall wart (that comes with it). MXR also has a DC Brick power supply that can work anywhere in the world with both 9 and 18v outputs.
What I really like about the Blueridge is the POWER this thing projects--everything else I plug in sounds "thin" comparatively--it's like plugging your iPod into a clock radio then plugging it into a high dollar Bose sound system.
My acoustic amps I simply set all the EQ flat and just use the MXR--in the studio I engage the lo-cut switch to reduce some of the power projection for recording.
My biggest use is live solo singer/guitar using an AKG stage condenser mic and pushing it all through a Digitech Vocalist LIve into either an acoustic amp or PA. The AKG is so "present" vocally it really needed a guitar there too--this was it.
