9.Channel 2 Select Switch: When you want to

use Channel 2, press this switch. The amber LED

above this switch lights up when Channel 2 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.

10.Gain: Use this control to adjust the input

gain for Channel 2. Towards the “–” side gives

you the classically British warm crunch. Towards

the “+” side gives you creamy smooth overdrive

with a touch of compression.

11.Treble: Use this control to adjust the top

end level for Channel 2. The Treble control

provides 12dB of boost or cut at 2kHz.

12.Mid Boost Select: Use this control to add

a 4~5dB boost from the low end up to the

midrange frequency selected: 250Hz, 500Hz,

750Hz, or 1kHz. There is, of course, no boost

when this control is at the “off” position.

13.Mid: Use this control to adjust the

midrange output level for Channel 2. The Mid

control gives you 10dB of boost or cut at

750Hz.

NOTE: The Mid Boost Select (#12) uses a differ-

ent circuit than the Mid control (#13).

14.Level: Use this control to adjust the out-

put level of Channel 2. Use this control along

with the Gain control (#10) to get the sound

you’re looking for on Channel 2. 

15.Bass: Use this control to adjust the low

end level for Channel 2. The Bass control pro-

vides 20dB of boost or cut at 50Hz.
