Henriksen Ampliers
Thank you for purchasing your Henriksen Amplier, we hope you enjoy
playing it as much as we enjoyed building it!
Since 2006 our mission has been to empower the working musician by
creating truly gig-able amplication solutions which are extremely portable,
durable, versatile in function and have the highest possible tonal quality.
We accomplish this by manufacturing all products ourselves; choosing
to locally source all possible materials, auditing and inspecting every
component and individually play testing every single amplier before we
ship it. We will neither build nor sell anything you cannot rely on at the
professional level, and we take as much pride in our customer service
as we do in our products. Please always feel free to contact us with any
questions, comments, or a shop tour if you’re in the Denver area, and
thank you again for your business.
Peter Henriksen, President

INPUT GAIN
The input gain control is to accommodate a variety of instrument outputs. In
the 12:00 position, the input gain is where you want it for most magnetic pickup
systems. For higher output pickups, active pickups, mics or effect devices, you
can adjust the input gain down so the preamp is not overloaded. For lower output
devices such as piezoelectric transducers, you can adjust the input gain up. The
input gain control setting should be experimented with in concert with the volume
control setting on your instrument and each instrument will be different so start
with the control at 12:00 and go from there.
INPUT JACK
The JazzAmp has a 1⁄4”/XLR combo INPUT jack on each channel. This jack may
be used to plug in a standard 1⁄4” instrument cable or an XLR cable. The XLR
is unswitched 48-volt phantom powered, so refer to the device manufacturer to
conrm compatibility.

5-BAND EQUALIZER
When it comes to the EQ controls, a little goes a long way so it’s best to start off
with them all set to the 12:00 position. The EQ is set up from LOW (100Hz) to
HIGH (10kHz). If you are new to using an equalizer, think of each EQ control
as a volume knob that only affects the volume level of its designated frequency
range. In simplest terms, the 100Hz control is a volume knob for your low E
and A string, the 300Hz control is a volume knob for the middle range of the
guitar, the 1kHz for the upper range, and the 3kHz and 10kHz is for the harmonic
overtones and the tweeter frequencies. The sound will vary from room to room,
and you should experiment with having the amp on the oor, tilted back, and up
on a stand to nd the best sound.
BRIGHT SWITCH
When turned on, the bright switch increases the higher frequencies of the signal
before going to the EQ. Note: If the input gain is set to 9:00 or below, the bright
switch will have little effect.

LINE OUT
The LINE OUT is both channels, post-EQ and post-reverb, and provides a balanced,
low impedance signal for use with mixing boards, PA systems, or recording.
HEADPHONE JACK
The HEADPHONE jack will defeat the main speaker (but not the extension speaker
output) and is post-EQ and post-reverb. CAUTION: Listening to headphones at high
volumes can cause permanent hearing loss.
EXTENSION SPEAKERS
You can connect a second speaker cabinet to your JazzAmp. This does not
disconnect the internal speaker, and any extension cabinet must be a minimum of
8 ohms and able to handle over 100 watts. DO NOT CONNECT OR DISCONNECT
AN EXTENSION SPEAKER WHILE THE AMPLIFIER IS ON.
POWER AND FUSES
Your amplier is factory set to either 115 volt or 230 volt power depending on which
country was originally shipped to. The voltage can be changed internally, please
contact Henriksen, Inc. or your dealer for specic instructions. For 230 volt amps,
fuse should be a 1A250V Slow Blow. For 115 volt amps, the fuse should be a
1.6A250V Slow Blow.
FX LOOPS
The FX loops send the signal from the amp post-EQ and return it pre-reverb.

TWEETER DEFEAT SWITCH
The tweeter is connected via a high-pass lter, using this switch allows you to
toggle the tweeter on and off without changing the sound coming through the
main driver.

FX LOOPS (CONT)
There is a switch to send level from +4db line
level to -10db instrument level, most devices
will work best with the switch set to line level.
WARRANTY
(Please take a moment to register at www.henriksenampliers.com/register). Our 2-year
warranty covers repairs not caused by abuse. Henriksen, Inc. or a licensed repair shop must
complete all repairs. Contact your dealer or Henriksen, Inc. directly for service.
FX LOOP

The jack is a Tip/Ring/Sleeve type, where the tip is the send and the ring
is the return.
To use the FX loop you will need a send/return Y-cable.

Gig bags for your JazzAmp 310 and 312 (or
older models) with shoulder strap and oversized
pocket large enough for a Real Book, cables and
a pedal or two.
Since we upgraded the JazzAmp lines to have
TRS effect loops, we have had so many people ask
where they can nd a Y-split cable to use it with that
we just decided to sell them ourselves. These are
10′ long snake cables, with 2′ of Y-split on the send
and return sides.
High quality, hand built instrument cables with a
LIFETIME GUARANTEE. Made with the same
components as the more expensive brands, but at
factory direct pricing!

About The Bud
A couple years ago we were cleaning out a box of stuff that belonged to
our late founder, Bud Henriksen, and found a mysterious speaker cabinet
he had made with a 6” speaker in it. The box happened to be the exact
size for our circuit boards to be mounted in, so we built it into a prototype.
The result was shocking, not only in the amount of volume which could
be coaxed from the enclosure, but also in how incredibly good the sound
was. Equally shocking was the response from our customers; obviously
there was a need for a tiny amp which sounded as good as our JazzAmp
line, but that wasn’t a toy or just a practice amp. So we set out to engineer
the smallest possible amplier a musician could still legitimately gig with.
Mission accomplished!
Not only does The Bud have an unmatched feature set and enough real
power to gig with, it has tonal delity that other small amps on the market
simply can’t compete with and it sounds just as amazing with acoustic
guitars as it does electrics so you can use one amp for both on the same
gig, something no other amplier achieves as well as The Bud.
