OWNER’S MANUAL

Dear Customer:

Thank you for your purchase of a Two-Rock amplier from Premier

Builders Guild.

As a discerning guitarist, you know the road to great tone begins
with great components.

Our Classic Design, 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 amplier.

Important Safety Instructions

1. Read these instructions

2. Keep these instructions

3. Heed all warnings

4. Follow all instructions

5. Do not use this apparatus near water

6. Clean only with dry cloth

7. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions

8. Do not install near any heat sources such as radiators, heat registers, plugs, and the point where they exit
from the apparatus

9. Protect the power cord from being walked on or pinched particularly at plugs and the point where they exit
from the apparatus

10. Only use attachments/accessories specied by the manufacturer

11. Unplug this apparatus during lightning storms or when unused for long periods of time

12. Refer all servicing to qualied service personnel. Servicing is requred when the apparatus has been dam­aged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen
into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has
been dropped

13. CAUTION: To disconnect the unit completely from the MAINS, unplug the unit. Turning the power switch
off does not disconnect the unit completely from the MAINS.

Front Panel Functions

Input Jack- High impedance input to the amplier. Plug in your instrument here.

Push/Pull Treble Control- Adjusts the high frequency response. In the full counter-clockwise position,

high frequencies are bypassed to ground. In the full clockwise position, high frequencies are allowed
to pass to the next gain stage. When the knob is in the “out” position, the high frequency response is
boosted. This is most effective when the input gain is set at 12 o’clock or lower. The effect is less dra­matic as the input gain control is adjusted past the 12 o’clock position.

Push/Pull Mid Control- 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 next gain stage. When the knob is
in the “out” position, the mid range frequency response is boosted.

Push/Pull Bass Control- 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. When the knob
is in the “out” position, the low and low-mid frequencies are boosted. This is a low frequency contour
switch, changing the low and low-mid response.

Gain- Adjusts the overall gain of the amplier. Start with this control in the 12 o’clock position.

Master Volume- Adjusts the output level of the amplier.

Reverb Send- The reverb drive control determines the amount of signal applied to the reverb tank. Low set-

tings will create a very open, small room reverb effect with a short decay time. Advancing the control clockwise
increases the signal applied to the driver, and a very saturated effect with a sharp attack and a long decay can be
obtained.

Reverb Return- The reverb return control mixes the reverb effect signal with the dry signal. At full counterclock­wise rotation, the reverb effect is defeated. Using the return control in conjunction with the reverb drive control, a
wide range of natural reverb effects can be produced.

Contour- The contour control is an active wide band sweep. In the 12 o’clock position, the amps’ frequency
response is at. Counterclockwise rotation reduces high end response and increases low frequencies. Counter­clockwise rotation decreases low end and increases the high frequency response. This control is very useful for
maintaining preamp tone control settings, while allowing a global adjustment to compensate for differences in

room acoustics, speaker cabinets, or bright to dark guitars (PRS Humbucker to Strat, for example). This control

also actively reduces the articulation available, allowing a softer setting, or extremely open and revealing, de­pending on your individual style and requirements.

Stand-by Switch- Should be in the “down” or “stand-by” position when you apply power to the unit. After a few
seconds, place the switch in the “up” position to use the amplier. You may leave the unit “powered up” and place

this switch in the “stand-by” position to mute the output.

Indicator Lamp- This lamp will illuminate when the power switch is in the “up” position, indicating the unit is
receiving A/C power.
