OWNERS MANUAL

Dear Customer,

Thank you for your purchase of a

Two-Rock

amplifier.

As a discerning guitarist, you know the road to great tone begins with
great components. Our classic design of carefully selected parts and
hand-built approach combine to make an extremely versatile instrument.

Please take the time to read this manual. We hope it will answer any
questions that you may have.

We extend a warm welcome to you as a member of a select group of
musicians who have chosen a Two-Rock amplifier.

Front Panel Functions

1. INPUT JACK - Input to the amplifier. Plug in your instrument here.

2. GAIN - Adjusts the overall gain of the amplifier. Start with this control in the 12 o’clock
position. The amount of gain set here determines the amount of gain feeding the lead channel.

3. EQ1 / EQ2 - This switch allows you to choose between 2 completely different equalization
settings. EQ1 is a lower gain setting, with extended midrange and bass available when used in
conjunction with the middle and bass controls as well as the deep switch. This setting is
suitable for any style requiring a pure clean tone with a nice round bottom and plenty of
headroom. EQ2 is a higher gain setting. This setting is suitable for any style requiring a clean
to slightly distorted tone in clean mode, and more gain in the lead mode.

4. TREBLE- Adjusts the high frequency response. In the full counter-clockwise position, high
frequencies are bypassed. In the full clockwise position, high frequencies are allowed to pass
to the input gain stage.

5. BRIGHT - Boosts the high frequency response.

6. MIDDLE – Adjusts the mid-range response. In the full counter-clockwise position, the tone will
be somewhat “scooped” of mid-range response, emphasizing the highs and lows. In the full
clockwise position, mid-range frequencies are allowed to pass to the input gain stage.

7. MID - Boosts the mid-range frequency response.

8. BASS - Adjusts the bass response. In the full counter-clockwise position, low frequencies are
cut. In addition, the response of the treble and mid-range controls is greatly reduced. In the
full clockwise position, low frequencies are allowed to pass to the next gain stage.

9. DEEP - Boosts the low frequencies. This is a low frequency contour switch, changing the low
and low-mid response.

10. LEAD GAIN - Adjusts the input gain of the LEAD channel. The GAIN control cascades into this
control. This level can be set to match the input gain or can be set higher for more overdriven
levels.

11. LEAD MASTER - Adjusts the overall output level of the LEAD channel.

12. LEAD - This switch sends the instrument signal through the lead circuit, adding extra stages of
gain to the signal and enabling the lead gain and lead master controls. To enable foot switch
control of this function, switch must be in the down position.

13. BYPASS - This switch bypasses the TREBLE, MIDDLE, BASS tone controls. To enable
footswitch control of this function, switch must be in the down position. NOTE: Boost switches
will still be enabled.
