1.Input Jack: 1 Meg Ohm input impedance 1/4”
input jack – plug your guitar in here.
2.Channel 1 Select Switch: When you want to
use Channel 1, press this switch. The green LED
above this switch lights up when Channel 1 is
selected. The BV300H uses instant access switch-
ing – when the footswitch (#28, rear panel) is
connected, either the front panel channel select
switches or the footswitch will select the
desired channel.
3.Gain: Use this control to adjust the input
gain for Channel 1. Towards the “–” side gives
you tight, dynamic clean tones. Towards the “+”
side you’ll get more crunch. Using a circuit
that was originally used for the bass or gui-
tar, the gain is mild, yet thick & punchy. (A
humbucker will push the preamp intensely into
compression.)
4.Treble: Use this control to adjust the top
end level for Channel 1. The Treble control
provides a range of 38dB at 5kHz.
5.Mid Freq Select: Use this control to select
the frequency where the Mid control takes
effect – 300Hz, 700Hz, 1kHz, 1.5kHz, or 3kHz.
6.Mid: Use this control to adjust the midrange
level for Channel 1. The Mid control gives you
10dB of boost or 22dB of cut at whatever fre-
quency the Mid Freq control (#6) is set to. The
Mid control is a peak/dip style filter.
7.Level: Use this control to adjust the output
level of Channel 1. Along with the Gain control
(#3), you can get the right blend of dynamics
for your playing style.
8.Bass: Use this control to adjust the low end
level for Channel 1. The Bass control provides
24dB of boost or cut at 50Hz.
