This unbalanced output is always on, independent of the mute function found on the front

panel. It can be used to connect a (rack)tuner or act as a simple, low quality line output.

The FX loop connectors work in conjunction with the FX loop section on the front panel

send : The send connector provides an

unbalanced output signal, capable of driving

any effect with a clean bass signal.

Note: If not used for the FX loop, the 'send'

can act as an unbalanced line output.

return : The return connector takes the signal

from the effects chain and feeds it back to the amplifier. How the signal is treated depends

on the settings made on the FX loop section on the front panel.

Note: If not used for FX loop, you can use this connector as an auxiliary input. See 'FX loop

section' above.

phase

: shift the phase of the send signal by 180 degrees.

Note: Many effects out there shift the phase by 180 degrees. When mixing a shifted return

signal with the original signal, the two will cancel eachother out completely or to a large

extend. By flipping the signal that's send to the effects to begin with, the returned signal is in

phase again with the rest of the preamp, negating the issue. So, if you experience loss of

perceived volume when mixing the wet and dry signal, flipping the phase button will usually

resolve this.

send level : The signal level required by various effects varies from small to (very) large. This

is rarely an issue, but depending on the bass being used, plus the pad setting on the front

panel, the level might not be optimal. Inside the preamp, near the send connector, you'll find

a jumper (JP1) used to boost the signal that's send to the connected effects.

● Jumper ON:

● Jumper OFF: +6dB (double the signal level)

Warning: Please treat changing this jumper as you would changing the tubes. See the 'how

to replace tubes' section below and ignore step 5 and 6.
