unprocessed clean sound, regardless of any effects turned on.
?EFF (effect) position: balanced output has the processed sound,
reproducing the all effects that are turned on at the time.
EXTRA Switch:
?CG. position: In “Common Ground” mode, balanced output shares
the same electrical grounding with the pedal. This is the most common
position.
?GL. position: “Ground Lift” is recommended under certain conditions
when your pedal and the equipment receiving its signal through
balanced output use incompatible grounding loops. In such scenario,
separating “grounds” might help reducing noise.
?Headphone position: it only amplifies the signal at the main “OUT”
jack. The balanced output signal is not changed, however, it forces
“ground lift” mode.
Main modules: pre-amp, drive and booster:
Pre-Amp:
Pre amplifier prepares the sound to be directly recorded from the pedal.
It's BSH's biggest module. These controls are part of the preamp:
?BASS, MID and TREBLE knobs: equalization of the respective
frequencies.
?LEVEL knob: preamp's output level, which is also the input signal to
BSH's booster. If high levels are combined with high booster gain,
some distortion might happen.
?SHAPE button: this changes the overall characteristic of the sound. It
acts mostly on mid frequencies, causing some compression.
To turn the preamp on and off, press both footswitches (F1 and F2) at the
same time. Preamp has a specific led in the main panel. “Shape” has
another led which will be on whenever the button is pressed. However,
note that shape will only act when the preamp module is on. Some people
will set the preamp and then leave it on 100% of the time. Other people will
use the preamp as an effect over the original bass sound, using it only as
needed. Both forms of use are correct.
Overdrive / Super Overdrive
This module adjusts the desired distortion of the pedal. These are the
controls:
?DRIVE and LEVEL knobs: intensity of the distortion, and its output
level.
?SUPER button: makes distortion more intense and aggressive. The
“overdrive” effect becomes a “Super Overdrive”. This button has its
own led which stays green in “normal” mode, and becomes red when
button is pressed (“super” mode).
?GATE button: BSH's noise gate. It works this way: 1) when there is
signal coming through, gate's led stays on and nothing special
happens. 2) As signal begins to fade, the led becomes weaker until it
shuts down. This is the moment when the noise gate is acting,
eliminating most background noise. Please, note that the noise gate
only acts when the overdrive module is turned on.
You turn the drive module on and off by pressing the respective “drive”
footswitch (F2). Drive requires the preamp to be turned on. Fortunately,
BSH handles that by automatically turning the preamp on and off.
Booster Module:
This is BSH's simplest module. It's an active gain stage that instantly
increases sound's level. Booster is entirely independent, so it can be
turned on anytime pressing the “boost” footswitch (F1).
“Boost” knob is the only adjustable control on this module. Use it to set
booster's gain from 0 (no effect) to 12 decibels.
At high settings, booster may cause distortion. If it happens, try to find a
better balance lowering levels on the preamp and drive modules. If those
are high, then booster might receive a strong input signal, and finally
saturate when trying to add even more gain.
