The biggest tip I can offer on the KBAC controllers is to make sure you read, understand, and adjust the trim pots to suit your needs. As the units come, the trim pots are set in a very generic manner. Adjusting the trim pots to suit your needs make a good thing even better.
OK count me as ignorant but I swear I thought Ed, was pulling my leg again!!!
I guess I learned a new terminology today!!! See, I is not to old to learn,...…………….. an old dog a new trick!!
From Wikipedia:
A
trimmer[1] is a miniature adjustable electrical component. It is meant to be set correctly when installed in some device, and never seen or adjusted by the device's user. Trimmers can be variable resistors (
potentiometers),
variable capacitors, or trimmable
inductors. They are common in precision circuitry like
A/V components, and may need to be adjusted when the equipment is serviced. Trimpots are often used to initially calibrate equipment after manufacturing. Unlike many other variable controls, trimmers are mounted directly on
circuit boards, turned with a small
screwdriver and rated for many fewer adjustments over their lifetime. Trimmers like trimmable inductors and trimmable
capacitors are usually found in
superhet radio and
television receivers, in the
intermediate frequency (IF),
oscillator and radio frequency (RF) circuits. They are adjusted into the right position during the alignment procedure of the receiver.
Trimmers come in a variety of sizes and levels of precision. For example, multi-turn trim potentiometers exist, in which it takes several turns of the adjustment screw to reach the end value. This allows for very high degrees of accuracy. Often they make use of a worm-gear (rotary track) or a leadscrew (linear track).

In 1952,
Marlan Bourns patented the world's first trimming potentiometer, trademarked "Trimpot", a name now
commonly used to refer to any trimming potentiometer.
