LR Baggs Feedback Master Preamp Review

LR Baggs Feedback Master Preamp
Average Reviews:

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.

Don't put up with feedback from your acoustic guitar - and don't let bad EQ kill your tone! Play louder and sound better with the Feedback Master. With TWO unique, surgically narrow fixed depth sweepable filters, the Feedback Master has everything you need to easily control feedback without ruining your sound. The circuitry is 100% analog, pure class A and all discrete for pure sweet sound. The Feedback Master will work with virtually any pickup, active OR passive. The Feedback Master comes with both a belt clip and a microphone stand adapter. Play Louder and sound better. The Feedback MasterTM is the best-sounding and easiest-to-use feedback remedy available for acoustic instruments. It features a phase inversion control and two precise Garrett Null sweepable notch filters to accurately locate and eradicate feedback from top and air resonances without destroying your tone. The circuitry is all-analog pure class A from end to end to provide great tone quality. Features Two proprietary Garrett Null sweepable narrow-band filters easily locate and damp air and top feedback resonances, controlling feedback without sacrificing tone Phase inversion switch for additional feedback control Adjustable gain for optimum signal level and lowest noise All analog pure class A discrete circuitry makes is utterly transparent and quiet Works as a standalone buffer-preamp with virtually any active or passive pickup Includes mic stand adapter and belt clip What do you mean by 'All discrete, Class A circuitry,' and how does that affect the sound? Much audio circuitry these days is put together with integrated circuits, or op amps. 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

DBX AFS-224 Dual Channel Advanced Feedback Supression Review

I am a 30 year+ giging modern jazz musician. Feedback in the monitors has always been a big problem, in many cases making me change the set or instrument. I now can play any acoustic instrument with drummers, amplified instruments... and the vocals can be loud and crisp with no feedback. Very easy to use as well

The AFS 224 Advanced Feedback Suppression processor was designed to provide state-of-the art feedback elimination processing, while maintaining a simple and intuitive control interface. From the powerful DSP module to the no-nonsense user interface, the AFS 224 provides all the processing and control necessary for both installation and live use. The AFS 224 is an absolute must for any live sound application.Ten and twelve filter feedback elimination processors have become the de facto standard, but the engineering staff at dbx have never been quite content residing in the neighborhood of the status quo. So, to raise the bar once again, they went out and developed a dedicated feedback suppression processor that offers up to 24 filters per channel with filter Qs up to 1/80 of an octave. To achieve these staggering numbers dbx utilized their patent-pending AFS technology that had previously only been available in the upper echelon line of products and made it available in this stand-alone processor, which takes all of the guesswork out of feedback removal. In addition to the plethora of feedback suppression filters available, the AFS 224 also offers selectable modes, live filter lift, and types of filtration, which are all readily available via the intuitive user interface front panel.
