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 compati-
ble 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 maxi-
mum. 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 sensitivi-
ty 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 cen-
ter 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.
