Bassbone V2 Preamp

CHANNEL-1
Think of channel-1 as a ‘straight-through’ channel whereby you will use
the EQ on your amp to set up the tone of your primary bass. Channel-1
is equipped with a control for adjusting the instrument level and a three
position switch for selecting one of two EQ presets.
Start with the LEVEL-1 control set to the 2 o’clock
position and use your instrument amplifi er to set the
overall volume and tone.
After you have dialed-in your traditional bass sound
on your amp, try the EQ-1 presets with your amp.
This switch can introduce one of two carefully crafted
preset EQ curves designed to bring a more modern
character to older vintage bass amps that may not
have the tonal range needed for a particular gig.
CHANNEL-2
Depress the SELECT footswitch to switch to channel-2. Think of
channel-2 as the 'override' channel. This features a powerful passive-
interactive EQ that lets you override the tone settings on your amplifi er
to create an entirely different bass sound.
Start with the LEVEL-2 control at the 2 o’clock position and adjust the
level to match channel-1. Use the three-band EQ to create a different
tonal response from channel-1. Stomp the SELECT footswitch to toggle
between channels and compare sounds.
The three-band EQ can dramatically increase or decrease the amount of
gain depending on the settings. For instance, rolling off low end with the
EQ will reduce the overall gain. Compensate by adjusting the LEVEL-2
gain until it matches channel-1. Once the EQ and level controls are
set, you can toggle between channels without adjusting your amplifi er's
volume or EQ settings.
Channel-2 is also equipped with a 3-position high-
pass fi lter HPF-2 that is used to reduce excessive
low frequency resonance that can cause a bass to
sound muddy and indistinct. The HPF-2 fi lter can be
particularly advantageous for acoustic bass players
who experience resonant feedback when playing live.
The HPF-2 fi lter has a fl at setting (fi lter bypassed) and two settings that
gently roll off bass. The middle setting rolls off low frequencies below
35Hz and the bottom setting below 60Hz.
