HOW IT WORKS
START-UP
- The far right knob on the V8 is a 3-position rotary switch. To start up the
V8, have your power amplifier muted or powered down so that when the V8 comes on,
there is no "pop" or "thump" that is delivered to the speaker. Follow this sequence for
safe startup and maximum tube life.
A. Turn the knob from "OFF" to "WAIT".
B. While on "WAIT", wait and count to 12 so the tubes can warm up
C. After 12 seconds, turn the knob to "RUN"
D. Now turn on your power amp or make your final connection.
Note: the middle "WAIT" position is not recommended as a mute or stand-by. If you
need to mute your rig for setbreak or when stepping away from your gear for a while,
simply turn the "GAIN" knob off. When you're done using the V8, simply turn it all the
way to "OFF".

impedance. It should comfortably handle most any guitar, steel guitar, bass guitar, or
acoustic instrument levels.
GAIN
- The Gain knob is your “volume” control. It's pretty simple, just set the gain
somewhere in the middle or just above, and let that be your baseline loudness position.
Adjust your power amplifier to make the final master loudness decisions. This should
then give you a wide range of loudness control with the V8's Gain knob.
BASS
- The Bass knob covers a pretty wide range of control. With the knob back at
around 9 o'clock, you have a relatively flat bass response. Below that you are actually
removing bass. At around noon the bass response will be a good baseline, typical
setting for many instruments and sounds. Above that, there's still some more to be had
if needed.
TREBLE
- The treble knob in the V8 is what's called "interactive" just like in the many
famous tone-stack amplifiers in the world. What this means is that it not only controls
the amount of treble, but it simultaneously adjusts the midrange. This type of EQ when
making "normal" settings will create a midrange dip. The more you crank the treble, the
lower the frequency of the midrange dip. When you cut the treble, the dip rises to higher
frequencies. You really don't have to think about this, but it's good to understand that
there's a LOT happening with the treble knob in a "tone-stack" type EQ.
