Follow these instructions to check the fit in your guitar:
1.
Place the guitar on a table.
2.
Loosen the strings and put a capo on the 10th fret.
3.
Pull out the string pins and pull out the ball ends of the strings.
4.
Position the guitar so you can comfortably put your hand into the sound hole
and feel the inside structures underneath the bridge with your fingers.
5.
Place a turned-on flashlight (good size please not just a key chain light) inside
the guitar.
6.
Position the flashlight way back in the lower bout of the guitar and let it shine
towards the sound hole.
7.
Place a small handheld mirror inside the guitar under the bridge. You may have
to use something to support the mirror in case there is a brace in the way.
Adjust the mirror so you can see the bridge plate when you peer through a
pinhole. You have to get one eye
directly
over a pinhole.
8.
Hold the cutout on the bridge plate between pinholes and sound hole.
9.
Allow for about an extra 1/8" (3mm) distance between pinholes and the bridge
plate edge for the ballends. A little less than 1/8" may be fine, just in case. A
ball-end may touch the pickup but it should not "bite" in it.
10.
The diagram should fit entirely on the bridge plate, however a small overlap on
the sound hole side is acceptable. It should not be more than 3/32" (2mm).
11.
If the diagram overlaps more than 2mm or if it does not fit between the X
braces at all, please order the 1/2" diameter MINI PURE Pickups. The Mini Pure
will sound just as nice and they will fit pretty much any bridg plate. They
provide a little less output than the standard size pickups though. The tone
quality is the same. Smaller bridge plates are usually more responsive because
they have less material. Like this there will be more vibration for the pickups to
work with. This almost makes up for the difference in output level.
