LR Baggs Feedback Master Preamp

LR Baggs Feedback Master Preamp Review

Simple to use, clean-sounding device. Baggs's
use of efficient circuit design delivers a clear,
transparent sound. This preamp doesn't color the
sound much.

The screws that attach the belt-clip to the outside
of the case are very short and apt to work lose.
They also, on my unit, caused the device to buzz
because they touched the metal on the inside. Some
kind of grounding problem I guess. My unit may
be defective but I never returned it to Baggs of
called them to ask about it. Instead, I just
removed the screws and have used the unit parked
on a table or on an amp... a lousy solution
admittedly, but at the time I was using this a
lot I was performing on a weekly basis and didn't
want to go without the unit while I returned it
to Baggs. I was pessimistic about the belt-clip
screw buzzing being a fixable issue at the time.

SO - it sounds great. It notch-filters feedback
admirably, but seems to have this design flaw that
made it inconvenient for me to use, even though
I put up with it for a few years.

These chips are versatile and easy to design with, but the drawback of that versatility is that this circuitry usually includes many extra parts that aren't needed in every application. These extra parts can cloud the sound and add noise. Contrarily, a discrete circuit has o
