RE: [Harp-L] how do you set the kinder afb?- even more questions



Concerning the "temperature sensitivity issue" in B Boggs' post:

Here is an excerpt of an email from me to John Kinder concerning a weird sound I experienced using the AFB+ outside, in direct sunlight, on a hot day, back in 2006. Following is JK's reply.

John [Kinder],

I experienced a little glitch while using my AFB+ with my Fender Blues DeVille 4X10 during an outdoor gig this past weekend, and I was hoping that you might be able to clear it up for me. 
I had the AFB+ connected and ready to play, when I got some severe crackling and "flubbing". The flubbing sounded like a 60Hz hum, but it shook the speakers very hard. In addition, there was no signal getting to the amp during the episodes.  When I plugged the mic straight into the amp, the problem stopped. I played "straight-in" for my hour-long set, and did not experience any difficulty. Before and since that one occurrence, I have had no problems with the AFB+. It seems to have been an isolated incident.


Hi John [Balding],

Thanks for the email!  The noise/flubbing sound problem you experience may have indeed been the AC line or perhaps a short-lived strong radio frequency (FM or un-modulated AM) pickup.  In any case, if it does not re-occur, then a mystery it remains.  The AFB+ should be able to operate in "Death Valley" outside in the sun during a scorching summer day and show no ill effects.  However, if any condensation of moisture occurs inside the box on the PCB, then you could experience noise/unstable operation.  One possible way for condensation to occur is if the AFB+ itself was cold and then suddenly moved into a warm, moist environment so as to cause a dew-point effect.

If you should have any further questions, please do not hesitate to contact me. I wish you and yours a happy weekend!

Sincerely,
John C. Kinder

Hello,
 
Thanks for all the time members have taken to post instructions for the Kinder AFB+ query.
In a discussion with a harp equipment tech; it was shared that the Kinder unit is sensitive to temperature (I quess if it went from a cold car to a warm room) and that could effect the settings.
Also, I set it for each mic, each time- with the middle knob, as John K. has posted.
With some amps, in my case, a Danelectro-made Montgomery Ward Airline, the sound is incredible dimed in an ear-bleed stage setting.
Crispy Crunch.
 
Best~

I¹ve also recently bought one of these and while I love the feedback
suppression thing, I¹m still having some trouble dialing it in.
Specifically, the gating effect (ie, dropout below a specific volume level)
can be very pronounced with certain settings. Does anyone have a more
precise description of what exactly the two outside knobs do? I understand
the center knob idea, but it might help to have a more informed approach to
getting the others to work consistently, especially when trying to adjust
after the band is up and running. Also- there seems to be differing opinions
on sequencing other pedals with the Kinder. I know Jason had it first in his
chain (after the wireless) but now I¹m hearing no distortion pedal should be
after it. Does that include delay? I¹m finding that I don¹t really need my
Blues Driver with the AFB, in fact it seems to add feedback unless I back
the output off a lot.
I¹m using a bassman RI with reduced gain preamp tubes and either a JT-30
ceramic or a 520 with a fairly hot CM element.
