But back to the benders, each one is slightly different but after using a bender for many years they're more-or-less interchangeable in use.
I would agree. But here are some of additional points of clarity worthy of additional discussion.
PULLING systems, be it neck plate or upper bout, are very similar in performance, they leave your picking hand free to navigate whatever it is you are doing, unencumbered.
There are many NET discussions about the various systems , which one is better etc.. The discussion that I find the most curious is those that say they are ruining the guitar with an installed system such as an Evans or a Forrest Lee jr etc , some even call it hacking up the guitar. Then there are those that say they can do everything they NEED or want to do with a Palm lever. Both of those leave me with questions.
Hacking up or ruining the guitar - These individuals have already decided that they will bring the guitar back to NON Bender one day, before they even began the journey. They need it to be reversable, like a Hipshot or a Palm lever. The Bender is a Novelty rather than a new Instrument.
Palm levers do all I NEED. In the Pedal Steel world that equates to I only need 2 Pedals and 1 knee lever, I'm never going to go beyond that.
I've joined plenty of NET discussions and they all end up in the same place at some point, many want to add a Bender pull but once it is on the guitar they don't know what to do with it because their fretboard knowledge or their THOUGHT process is still back in NON Bender territory. So when they get frustrated the easiest thing to do is reverse the installation.
Now I'm no Bender Savant here , but I did recognize early on that to become more efficient with the B or G pull, regardless of how it mechanically operates, it required stepping out of the OLD fret board box and expand into new territory, meaning different root positions and intervals which place the B or G pull (or release) into the ZONE.
Another thing often overlooked is while of course these are Benders, meaning they PULL the B or G UP , they also RELEASE back to the natural note. Meaning we are beginning a phrase with the string already PULLED ( ahead of time) but when we execute the phrase, its the RELEASE that is the primary phrase. This is very difficult to do with a Palm Lever.
The other part of many discussions is that many "new or infatuated" players want to sound like a Pedal Steel Guitar, so they add a Bender. Within a day or so they learn that B or G Benders don't actually emulate a Pedal Steel. Sure some phrases come close and do, but overall they do not. So now they are back to what do I do with this contraption ? There are basically 3 options- 1- remain where you are with fret board knowledge 2- Study and IMPROVE your fret board knowledge or 3- REMOVE the contraption from the guitar. Many choose option 3 .
OK--- There is a serious problem with #2- Once we study and get more acclimated and improve, we are not happy with just ONE Bender guitar ! Next thing ya know we have a room full of Bender guitars ! There may be medicine available for the phenomenon !

Discussion Coming soon
Which Bender - B Pull or G Pull ? whats the difference ? But we'll save that for another day
Those of us that have Glaser Convertible systems, ( or double Bender) we can make the swap and probably answer our own question
