Tech 21, the Company

Tech 21, Inc., was formed by a guitarist possessing the unusual combination
of a trained ear and electronics expertise. In 1989, B. Andrew Barta incorpo­rated Tech 21 and made his invention commercially available to players and
studios around the world.

SansAmp™

pioneered Tube Amplifier Emulation in
professional applications for recording direct and performing live, and creat­ed an entirely new category of signal processing. While there have since
been many entries into this niche, SansAmp continues to maintain its
reputation as the industry standard.

After developing a variety of SansAmp models, Tech 21 expanded its offer­ings to include effect pedals; a compact, battery operable MIDI footcon­troller, the

MIDI Mouse

;

as well as “traditional” style amplifiers for guitar and
bass. Each product is thoughtfully and respectfully designed with the player
in mind. Our goal is to provide you with flexible, versatile tools to cultivate,
control, refine and redefine your own individual sound. Tech 21 takes great
pride in delivering consistent professional quality sound, studio to studio,
club to club, arena to arena.

Bronzewood 60, an Overview

Tech 21’s proprietary, 100% analog circuitry has been adapted from its
SansAmp configuration into a dual-channel, 60-watt combo amp format
specifically for the acoustic player. Our exclusive technology removes the
harsh harmonics associated with piezo pickups and delivers a natural
warmth and presence for which Tech 21 is known.

Compact and lightweight, the Bronzewood 60 is loaded with exceptionally
extensive features, including a compressor and a top-of-the-line full-length,
Accutronics™ 3-spring reverb. The distinctive brown crocodile embossed
vinyl covered cabinet is complemented by a custom grill covering and
decorative piping detail.

For live and studio applications, our highly-acclaimed SansAmp Tube/
Microphone Emulation technology enables you to go straight into the mixer
of a PA system or recording console via the XLR direct output.

With the Bronzewood 60, you get a lot of sound in an affordable, cost­effective

38 lb.

package.

IMPORTANT SAFETY INSTRUCTIONS

The Bronzewood 60 is powered by potentially hazardous voltage. Therefore, observe
the following safety precautions:

WARNING: To avoid the risk of fire, electric shock or injury, do not expose this unit
to moisture. Do not remove the chassis from its cabinet, or remove metal covering
from chassis parts. Removing the chassis from its cabinet exposes extremely danger­ous high voltages. There are no user-serviceable parts inside. Hazardous voltages
are present inside the chassis. Refer all servicing to qualified personnel.

CAUTION: Never modify the power cord. If the original power cord becomes dam­aged, refer your amplifier for servicing.

WARNING: Attempting to repair this unit is not recommended and may void its
warranty. NOTE: In the U.S. and Canada, servicing is performed at factory only. In
other countries, please refer repairs to the local Tech 21 authorized distributor.

ADDITIONAL PRECAUTIONS:

1. Do not allow liquids or objects to penetrate unit.

2. When in use, provide proper ventilation at top and back of unit.

3. During heavy use, chassis may get hot to the touch. Handle with care.

4. Protect unit from strong impact.

5. Do not locate near heat.

6. This unit must be earth grounded.

QUICK START INSTRUCTIONS

Here’s how you can get your Bronzewood 60 up and running before you read the
entire manual. Note: By not reading the manual, you’ll miss out on how to get the
most out of your new investment!

1. Plug your instrument into the top-panel Guitar input jack (on the left side).

2. Plug the AC cord into a wall socket.

3. Turn on the Bronzewood 60.

4. Use the Start-Up Sample Setting on page 11.

5. Play your guitar and you should hear a sound coming through the amp. If not, check
that your guitar’s volume control is turned up, recheck your connections, and be sure
your cable isn’t faulty. If there is still no sound, refer to factory or qualified technician.

TOP PANEL

The Bronzewood 60 is designed with

active

tone controls, which cut and boost,
rather than traditional passive controls which only cut. This gives you greater control
over a larger range of adjustability. As you experiment and become familiar with the
controls’ interrelationships, you’ll easily be able to dial up the best sounds for you.

It should be noted that you need not necessarily set everything at max to

obtain maximum results.

GUITAR CHANNEL

GUITAR Input Jack

Input is 1/4”, 4.7meg , instrument level. The unusually high impedance was designed
with piezo pickups in mind to provide maximum output and dynamics. It is also compati­ble with low impedance input signals, should your guitar have a built-in preamp.

PREAMP SECTION:

COMP Switch

Activates the Compressor function.

COMPRESSOR

Controls the amount of compression, ranging from 1:1 at minimum to 5:1 at maxi­mum. We recommend using this effect sparingly, as too much may cause acoustical
feedback problems. (See

Noteworthy Notes, #5

, on page 9.)

PHASE Switch

Reverses the input of the guitar signal to help combat feedback. When

out

, the out-

put (of the speaker) is in phase with the input. When

in

, the output (of the speaker) is

reversed. If your instrument feeds back, try positioning the switch

in

to reverse the

phase. If the feedback remains, return the Phase switch to the

out

position before

proceeding with diagnosing the cause. (See

Noteworthy Notes, #5

, on page 9.)

PREAMP

Controls the amount of gain of the preamp. We recommend starting with this control
at 12 o’clock. If you have a weak pickup, try 2-3 o’clock. If you have a hot pickup,

3

decrease to 10-11 o’clock. Of course, rely on your ears to determine the most
appropriate setting for your instrument.

NOTCH Switch

Activates the notch filter.

NOTCH

Notch filter is sweepable from 50Hz to 300Hz. It is designed to diminish the sensitivi­ty for feedback, caused by the resonating, low acoustical frequency of your guitar.
Effective, yet gentler than most notch filters, it should not adversely alter the tone.
For an average size and weight acoustic guitar, a setting of 150Hz, as shown in the
Start-Up Sample Setting (on page 11), should be adequate. Different models and
sizes, however, may require further adjustment.

TONE SECTION:

MID SHIFT and MID

These sweepable, semi-parametric EQ controls range from 170Hz to 3kHz, ±16dB,
respectively. With the Mid Shift control, you can select the center frequency of the
mid-range control (Mid). Note: If you set Mid Shift at 1kHz, Mid operates as a
traditional mid-range control.

LOW and HIGH

Specifically voiced for acoustic guitar, these active EQ controls set the tonal balance
of the amp relative to your environment. Boost or cut ±12dB by turning from the cen­ter point (12 o’clock).

BLEND

Allows you to blend the direct instrument signal of your guitar with the SansAmp
Tube/Microphone Emulation circuitry. It is designed to gently round off the top end of
the signal and is particularly useful for older style piezos. Newer, more sophisticated
piezos may need less, or none at all. NOTE: At minimum, the SansAmp circuitry is
bypassed and all other controls remain active.
