Two-Rock CLASSIC REVERB SIGNATURE, Owner'S Manual, Page: 4 / 10

BASS - Adjusts the bass response. In the full counter-clockwise position, low frequencies are cut
and the response of the treble and mid-range controls is greatly reduced. As this control is turned
up, the bass frequencies are increased and allowed to pass to the next gain stage.
EQ1/EQ2 Switch - This switch lets you choose between 2 completely different global equalization
settings greatly affecting the overall personality of the amplifier.
EQ1 is a lower gain, higher headroom setting with extended midrange and bass response.
This setting is suitable for any style requiring a pure clean tone with a nice round bottom end
response, and plenty of headroom. It may seem weak and thin sounding when first switching to
the EQ1 setting from the EQ2 setting. This is due to the lower gain structure of EQ1 thus the gain
and master settings as well as the tone controls do need to be readjusted in order to take full
advantage of the EQ1 setting.
EQ2 - This setting has more available gain yet still provides plenty of clean headroom if desired,
along with a full and balanced response overall. This is the setting that most players will prefer to
use especially with single coil pickups, and or any type of lower output pickups.
GAIN - Adjusts the overall gain of the amplifier. Start with this control in the 12 o’clock position
then adjust to taste. This control determines the initial character of your tone, from cleaner/brighter
tones at low settings to fatter/warmer tones at higher settings. As you turn this control up it also
introduces more gain and bass into the signal path, and reduces the amount of available clean
headroom especially when the master volume is set higher.
GAIN STRUCTURE - The 3-position gain structure switch alters the sensitivity and overall tonal
character of the amplifier’s input stage. This is very effective for dialing in the initial gain and
dynamic feel of the amplifier, and thus the way it responds to your guitar’s pickups and your
playing style.
The up position maintains the familiar Two-Rock feel and midrange response found in the Studio
Signature’s legacy predecessors.
The down position has a vintage blackface feel with a scooped midrange response and slightly
less gain which can be very effective for dialing in a cleaner, bouncier tone especially with
humbucker pickups.
The middle position offers the most gain of the three positions, essentially lowering the clean
headroom of the input stage and creating a more aggressive edge of breakup tone.
MASTER
- Adjusts the overall output level of the amplifier. At lower settings on this control the
amp will be much cleaner sounding as well as lower in volume. As this control is turned up the
power section of the amp begins to work harder which increases sustain, fullness, and touch
dynamics as well as raising the volume of the amplifier. At higher settings on this control the power
section will be pushed into natural overdrive especially if the Gain control is set higher.
BYPASS Switch
- Referred to as Tone Stack Bypass, this switch bypasses the Bass, Middle, and
Treble controls effectively turning them up all the way and increasing both the volume and
perceived mid-range response. The Bright, Mid, and Deep switches remain active in the Bypass
mode. This function is also foot switchable. To enable footswitch control of this function, the switch
must be in the down position.
