Callaham describes it as boosting the mids and bass. I'm getting ready to install a baseplate, but I was wondering, does anyone know if you can take a baseplate off once you're glued it to the pup?
I recall Jason Lollar saying that it doesn't change anything, or at least not enough to be noticeable.
There is quite some confusion about the Tele bridge base plate. everybody tries to explain the reason for this baseplate with only one function, but this baseplate has, in reality, 3 different functions:
#1 Only the steel baseplates corresponds to function A, B, and C.
- A. Ferromagnetic functions
B. Electrodynamic functions
C. All metal plates provide extra shielding.
#2 Brass, copper and aluminum baseplates have no ferromagnetic functions, and therefore, only correspond to function B and C
#3 Alloys of the 300 series stainless steels have neither ferromagnetic nor electrodynamic functions and therefore, only correspond to function C.

Brass Base Plate notice that the base plate also serves as the ground for the bridge pickup.
Function A
Leo Fender used copper-plated steel baseplates on the Tele bridge pickup to stabilize and to increase the magnetic force of the relatively weaker Alnico 3 slugs. The ferromagnetic steel plate increases the inductance of the coil (like increasing the number of turns on the coil).
The steel baseplate also transmits from the steel bridge mount via the steel mounting screws some of the body vibrations into the pickup, resulting in that typical Tele twang. As a negative, this is also the cause of microphonic squealing at high volume levels.
Function B
Baseplates made of steel, copper, brass or aluminum are the cause of eddy current interference. Eddy currents shift the resonances toward the lows, resulting in a fatter, more pleasant tone, especially in the bridge position. If you dont want to increase the inductance of the coil and the magnetic force of the magnets, aluminum and brass baseplates are ideal to fine tune the tone of single coil pickups.
These baseplates can be very effective on traditional single coil pickups with alnico slugs, but on many different designs, the result can be disastrous.
Also, the thickness of the baseplate is very important if the plate is too thin, the effect is very little, but if the plate is too thick, you may end up with a muddy pickup. For excellent results, keep the thickness of the plate between 1/32 and 1/16 and make sure that the plate is firmly attached to the pickup.

I didn't say he was right, I've never tested it myself. Just trying to help the OP by quoting someone who knows what he's talking about.
The callaham baseplat I have is just a metal baseplate with painters tape on one side and the directions say to use a bead of silicon adhesive and attach the baseplate to the bridge pickup tape side down... Does this sound wrong to anyone?
Just trying to provide some references and not just hearsay.![]()
From Jason Lollar's website FAQ.Do you make a metal base plate for Strats pickups?
I did some testing on what makes a Tele sound like a Tele and how well a similar base plate would work on a Strat pickup.
Testing was this: I made a Tele pickup and 2 Strat pickups with the same size and type of magnet same coil height and the same turn count. I put steel base plates on the Tele and one of the Strat pickups and left the other Strat pickup bare.
I have two Strats that are as close to identical as you can get and they have matched pots—both guitars have pots and caps that read the same. I put one of each type of Strat pickup in each of the guitars.
I could hear the tiniest bit of difference but the other people listening did not hear it. The base plate seemed to add the slightest amount of compression I could "sense." Maybe I could hear it only because I was playing the guitars. But maybe I didn't actually "hear" it; maybe I felt it more than heard it.
There was no difference in volume between the two. I installed the Tele pickup into a traditional Tele bridge and mounted it on a Tele with pots and caps that matched the Strats. I got about 15% to 20% more volume out of the pickup, a little more bass and more aggressive tone. Most noticeable was the volume boost. I have also made Tele pickups without the base plate—they have a little less up front aggressiveness. If you measure a Strat coil lets take one at 2 henries for example and you put a steel plate on the bottom the inductance will raise to approximately 2.15 henries. So you can measure that something is actually happening, but it is hard to hear the difference and I have pretty good ears. After this I decided not to recommend a base plate on Strats. It just doesn't seem to have enough effect to make it worthwhile.
