"Know your monkey"
The FBD Po is a pretty amazing unit, most people don't relaize what it can do. If you think you can just plug-in and be feedback-free, you might be dissapointed. Factory presets 'may' work in some limited situations, but actually taking the time to figure out the working platform will be very usefull and it'll make you appreaciate the units abilities and a true friendship will blossom.

For $99 you get 12 channels of either stand-alone or mixable parametric eq and feedback suppression. Feedback detection rate is adjustable and one of the features that's a 'must-learn'.

Ease of Use
'Ease of use' is always dependant on ones knowlage of the unit. Jog wheels are not that easy/fun to use, but that's the world you're in here~~~'jog wheel and a small-screen digital'. The FBD Pro 'is not' hard to use, what it may be for most is 'hard to understand', but once understood, you'll have strong confidance to make settings/adjustments with no problem, you might even be looking for a reason to make a setting, its that easy once understood. The manual is 'German-mind' into english, so 'strike one'. What I tell people is "Envision the working platform as a mixing board" you have 12 channels, so~~~ it could be viewed like a 2 channel 12 band graphic EQ with each channel able to be programmed any way read more you like and in no particular order...another anology- Two seperate 12 channel mixing boards. Each of the 12 channels are programmable with either 1)a paramaetric-EQ (setting you choose) 2)a roving (AU) feedback filter. 3) a set feedback filter (SI) which 'locks onto' a freq. and stays locked all by its own doing. These are the 3 functions the FBD offers---> EQ, AU and SI The manual will clarify these 3 functions and their abilities. Its all a matter of decieding which function to put in each of the 12 channels. So~~~in channel 1 through4 you can set SI~~~ channel 5 you can set an eq notch (say -3 at 2.5K),~~~~ on channel 6 you can have another SI,~~~ on 7 and 8 'nothing' if you want~~~~ 9 through 12 again EQ natchos without bathtub cheese and so forth. A mistake a lot of people make is 'overuse'. You don't need to run all 12 channels of feedback supression, as this is where sound quality (EQ curve) can become compromised. You can run 3 out of the 12, or 7 out of 12, or any combanation. I've never had the need to activate all 12 channels and even Behringer factory pre-sets have a few of the 12 channels 'unprogrammed'. The option 'is' here to use all 12 channels if you use the unit as EQ-only, which is possible and cool i.e. Top-bank of 12 for EQ-Only (FOH) and the bottom bank of 12 channels programmed for feedback supression on the monitor mix. Mind you, setting parametric EQ with a jog wheel on a small screen is tedious and takes knowing the ISO band for stress free stage eq'ing. Overview~~~You can put any of the 3 functions (EQ,SI,AU) into 'any' of the 12 channel's, so we're talking flexability here. You can set bank A of 12 channels for FOH and bank B for Monitors, or run 2 monitor mix's, or even 'bridge' both banks of 12 together (mirror settings). Each and every AU and SI filter you programe can also be 'gain' adjusted 'independantly' like levels on a mixing board (major flexibility). Setting gain is explained in the manual and pretty easy. -6 is suggested as a good 'overall' gain setting, though just remember, -3 is slow to react and -9 is quicker to react. Gain setting is adjustable -3 through -9 try them all out. Once you 'understand' how to use Feedback destroyer, it becomes your friend and you'll use it confidently and often to imprees both musicians and audiences with higher gain before feedback levels.

All electronics parts will eventually fail, its just a matter of when. Unfortunately, an electronic parts life-span cannot be tested. Just at 'launch' of the first Saturn-5 rocket into space, some 40,000 parts failed, causing a 99% run efficiency, a lot we're electronic.

If this is what you need, its a great deal.

Manufacturer Support
Behringer tries, which is at least 'hope'.

The Wow Factor
You need 20/20 vision to get along happily with Behringer. Would suggest flourescent paint on all audio units silkscreen graphics, then add black-lite, problem solved.
