Peterson, Bass Luthier Repairman Extraordinaire
I first met Jon Peterson more than 15 years ago, long
before we started this violin shop. Jon, is known
internationally as one of the finest bass repairmen (luthiers) in
the world. For more than 40+ years Jon owned and operated his
World of Strings in Long Beach, CA and has recently downsized.
While he still works in the LA area, he combines his time between
work a small workshop space in Malibu, his home shop in Buena Park,
and now with us here at Arizona Fine Violins.
Here's his small (contact) website,
Jon Peterson Upright Bass
He now comes to Mesa and works in our shop every 2 months or so.
Appointments for him to do bass restorations are planned and slotted
months in advance. He's the best bass guy on the planet and is
always worth waiting for. If the restoration or work needed is not
super major, he will do the work completely while he is here, where
he usually stays between 1-3 weeks per visit. If it is a major
restoration, with the customer's prior approval, he will even
sometimes take the bass back with him to California work on and then
complete it in Arizona on return. Arizona is the perfect
place for heavy bass restorations. First, the climate is
almost always super dry here. The humidity down to between
10-40% which is usually the most optimal setting for taking apart
and putting pieces back together again. The wood is dry and at
it's smallest, contracted state. This is the perfect time and
place to do the bigger restorations: If wood contains any
humidity (during the repair and gluing process), when the bass
eventually then shrinks (in the drier or winter months), it will
greatly increase the chances for re-cracking.
Not only is Jon totally at home with the major restorations, he is
also extremely well known for bass set up conditions, playability
and optimal sound for your bass. I have on occasion driven (in
one day), round trip 800 miles just to have him tap the sound post
of my Italian bass and tweak it to play better! Yes, I was
tired, but extremely happy that my bass played so well again.
Jon has seen, adjusted and repaired almost every kind of bass and
What, no bridge adjusters? The very first time that
I met Jon, I decided to drive from Phoenix to Long Beach for him to
work on a bass that we were selling, but had a major wolf note on
it. I just couldn't show it like that... It was a nice, old
German bass, yet had an F# on it that would sound like a failing
propeller plane (WWII) that was being shot down. I had heard
about him and his shop for years, but just thought it too long of a
drive, with hotels and everything to really think about checking him
out. The bass had a huge, fat neck, a badly (ruined)
bridge that needed replacing and again...that wolf!
When I arrived there from the 400 mile drive, Jon told me to go
ahead, have some lunch and come back later that day.
When I did, the neck looked and felt incredible (a rasp file will do
wonders when you know how to use it!), and it had a new bridge
fitted with the strings already nice and low, as I had asked.
That old German bass, now sounded like one of the nicest basses I
ever played. No wolf either!! I was greatly
impressed to say the least. Who was this guy??!! It was then
where I asked Jon, "hey, can you please install those bridge
adjusters in now for me?" Jon replied: "Well sure, if that's
what you want, but with a bass that is so 'dialed in' now, do you
really want to do that?" Our customer/player that purchased
the bass really wanted the bridge adjusters in, which I also agreed
with too. After he installed them I was blown away with how
that bass changed instantly: The wolf note was back, the bass
didn't have the same sound as it did before either. The timbre
changed (less complex now). I was shocked to say the least!
After about a half hour, shaving and changing the dimensions of the
bridge and re-positioning the post, the sound was pretty much all
I learned a few valuable lessons that day. First,
that this man is a genius and that if you are able to and live in a
climate that is not too extremely seasonal, one can use a bridge
without adjusters and that it opened a whole new world of bass set
ups: A combination of bridge adjustments, string height and tension,
with sound post adjustments can most greatly change the character of
an instrument. This was the beginning a truly magnificent
mentorship I received from Jon of which I will be grateful forever.
You know the old saying...you can feed a man, or teach him to fish.
Jon is 'old school' and will show anyone anything that he has to
For bass set ups to major restorations, (no matter where you live
in the world), we can do it all here. Kindly contact us to set
