1. Nutube BIAS

You can control the bias voltage of Nutube for CH1 and CH2 individually.

VINTAGE:

Decreasing the voltage makes the amp sound like a vintage guitar amp, this sometimes makes

your tone feel a little more unstable (like the old days).

MODERN:

Increasing the voltage creates more gain, and makes its tone smoother.

2. EFFECT LOOP

This has SEND and RETURN jacks, and a SERIES/PARALLEL switch.

This can be switched On or Off by the foot switch.

3. FOOTSWITCH

There are 2 foot switch jacks to switch the setting of the amplifier as below.

Optional VFS2 or VFS2A is accepted.

TIP!

You can also use a commercially-available open/close type footswitch with a TRS standard phone jack

connection.

4. EMULATED LINE OUT

This output has a built-in analog speaker cabinet emulation circuit. This sounds like you’re using a well-

known dynamic microphone in front of your speaker cabinet.
