FRONT PANEL
The Landmark 600 is designed with
active
controls, which either boost, or cut and
boost, rather than traditional passive controls which can only cut. This effectively
doubles many of the control’s capabilities, giving you a much larger range of adjusta-
bility and, ultimately, more variety. It should be noted that you need not necessarily
set everything at max to achieve maximum results. As you experiment and become
familiar with the interrelationship of the controls, you’ll easily be able to customize
your own sounds.
Channel Selector Switch
Manually switches between channels when there’s no cable plugged into the rear
panel Footswitch jack. To remotely change channels, use any standard passive
footswitch or Tech 21’s Optional Footswitch (Model #BFSW)
which will override the manual selector switch. (For more
information, refer to page 8.)
Gain
A 10dB gain boost to set up the pre-amp for different pickups.
For example, with lower output passive pickups, you can have
punchier sounds with Gain engaged. Conversely, with higher
output active pickups, you can have a cleaner sound with Gain
disengaged. Of course, you can also obtain over-the-top distortion
by using high output pickups with Gain engaged.
Input Jack
Faithful to the original designs of traditional tube amplifiers, this 1/4" Input is high
impedance 1M . The typically additional low sensitivity input, however, is not needed
due to the Gain switch.
CHANNEL 1
Channel 1 offers an entire sound spectrum of the most coveted traditional bass amp
rigs, from vintage to modern styles. You can also obtain
overdriven sounds without
having to invest in a complex system with multiple rack effects.
Drive
Adjusts the overall amount of gain and overdrive, similar to when the output section
of a tube amp is being pushed.

Bass and Treble
These active tone controls cut or boost ±12dB from unity gain at 12 o’clock. This
powerful EQ section effectively reduces the need for a fixed frequency mid control
and enables you to achieve an extensive variety of curves, including a “mid-cut” as
well as a “mid-boost.”
Adjusting Mid-Range Content:
The mid-range level of Channel 1 is preset.
Boosting
Bass and Treble gives you the equivalent of a “mid-cut” @ 750HZ where
the relative mid-range level is lower than the
Bass and Treble frequency levels.
Cutting
Bass and Treble is the equivalent of a “mid-boost” @ 750HZ where the rela-
tive mid-range level is higher than the
Bass and Treble frequency levels. NOTE: The
overall output level will change in relation to the adjustments you make with the EQ
controls. You can compensate accordingly with the
Level control.
Presence
Brings out the upper harmonic content and attack. For a smoother high end and for
clean settings, decrease to taste.
Blend
Allows you to blend the direct instrument signal with SansAmp Tube Amplifier
Emulation circuitry. In most cases, you will probably have this set at maximum (100%
SansAmp). For certain applications, however, such as an ultra-transparent sound or
for use with piezo pickup-equipped instruments, you may want to blend-in the direct
signal to achieve your desired sound. While the SansAmp Tube Amplifier Emulation
circuitry is bypassed when
Blend is at minimum, the Bass, Treble and Level controls
remain active.
Level
Adjusts the volume level of Channel 1.
