MID 2: This control adjusts the amount of mid range frequency content, peaked at
750Hz, within the channel. Turning the knob to its maximum position (fully
clockwise) boosts the mid range frequencies +15dBu. Turning the knob to the
minimum position (fully counter-clockwise) reduces the mid range frequencies -5dBu.
The 10 o'clock position would be flat or no change.

TREB: This control adjusts the amount of high frequency content, peaked at 4kHz,
within the channel. Turning the knob to its maximum position (fully clockwise) boosts
the high frequencies -i-18dBu. Turning the knob to the minimum position (fully
counter-clockwise) would be flat or no change.

Distortion Channei

BBE PROCESS
15.
IN: This switch engages the BBE process. When depressed, the "IN" position, the
"GREEN" LED will illuminate. When in the "OUT' position, the "GREEN" LED will not
illuminate, indicating that the BBE process has been disengaged.
16.
BBE PROCESS: This control introduces the
BBE process
which has specially
modified for the BBE 381 Guitar Pre-amp. The BBE process gives the user a more
detailed perception of tonality, added "bite" and increased clarity. The guitar's lower
tones will be tightened without losing their thunderous effect... all without adding or
creating any additional noise or harmonic distortion. When the knob is in its
minimum position, no process is taking effect and the circuit is in its noise
suppression mode. Turning the knob clockwise will introduce the BBE process.
Adjust the knob to mix the desired amount of process for your own needs. The BBE
process also has its own in/out switch for comparison of the processed to
unprocessed signal on the front panel of the BBE 381 pre-amp. Experiment with the
process. Use the BBE as an extension of the tone controls. Please note that the
BBE process is not an effect, but an improvement. A good place to start with the
BBE process is to set the knob to its12 o'clock position and adjust accordingly.
Note: The BBE process is applied before the effects send.
