Kahler Hybrid 7300 Tremolo Install
In the early ‘80s, I was basically living out Tremolo Profile
of my suitcase, eating Top Ramen twice a Kahler’s 2200 Professional stud-mount

up over the horizon, I would realize I was in chosen the 2300 Professional flat mount,
for a long day. which offers a few extra options for a few
extra bucks. A critical component in all of
Kahler’s cam-operated tremolos is the use
of 2-R2ZZ precision ball bearings, which
create the ultra-smooth feel and allow the
tremolo to come back to intuneness.
For a routing template, I used our 3/16”
acrylic template which is designed to take
a leaner cut from a pre-finished guitar. To
keep the route tight I used a 3/8” diameter
ball-bearing router bit to follow the template, routing out the cavity to a ¾” depth
Another ingrained memory from that
time is how this unique, wicked-looking
tremolo generated a frenzy among guitar
players. Every band that I ran into on the
road had at least one member using this
contraption. It was the one and only Kahler
tremolo by Kahler International, Inc. You
could truly say Kahler was taking the guitar
world by storm.
Measuring Up
Sure, there were other off-the-wall innovations being developed as there still are
today, but Kahler managed to break it all
down and ask a simple question: what are
guitarist’s problems, and what are solutions
to those problems? If you can provide that
solution, and do so with the best product
possible, you’ll win over players. Kahler
did that, and is still kicking after over two
decades of global change in the music
industry. The Kahler tremolo is still the first
and only choice for many guitar and bass
players alike.
I used my Stew Mac precision straightedge, laying it across both sides of the
fingerboard. As it extended out over the
body, I marked the straightedge lines
onto tape that I had previously placed on
the body. Measuring between these two
marked lines established the center and
the scale-length of 25-1/2” to position the
cardboard template Kahler provided. Note:
Do not mark the center line gauging by
the two front mounting holes of the cardboard template as they are not on center.
I marked center by the inner cutout of the
template. This is used as a guide for locating the area to be routed and locating the
four screw mounting holes; it’s not intended to be used as a routing template.
We were then ready to mount the tremolo.
The chassis ground wire was channeled
through the body and was making contact
on the underside of the tremolo for passive pickup compatibility. Kahler’s six-way
adjustable saddles made the setup and
intonation a breeze. Thanks to Robert
Buffalo for allowing me to use his guitar
for this article.
