We wish you a lifetime of good playing and

remember to always have fun!

GK Philosophy

I have never seen the point in doing things the

way others have done them. I also have not

been very interested in following the latest fad.

I’m a Stanford educated engineer who worked

my way through school as a musician.    Like

all musicians, I have lugged amplifiers up

stairways and into car trunks, always wondering

why these things had to be so heavy, bulky, and

hard to handle.

As the principal innovator at GK, our products

reflect my attitudes and life experiences. I

don’t model my designs after other

manufacturers’ products. Instead, I believe

new and old problems are best solved with new

solutions. Having taken our own path, GK

products enjoy a unique, unmatched sound,

allowing you every opportunity to make an

original statement.

Having supported my products for over thirty

years, I have learned from the story they tell.

Gallien-Krueger is a reflection of that story, and

has a commitment to support that legacy. Just as

the products I created over thirty five years ago

are still telling their story, the products we create

today will be talking to us tomorrow.

We’ll be listening,
