OWNERS MANUAL

Dear Customer,

Thank you for your purchase of a

amplifier 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 amplifier.

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 specified by the manufacturer

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

12. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has
been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled

switch off does not disconnect the unit completely from the MAINS.

Front Panel Functions

1.

Input Jack

High impedance input to the amplifier. Plug in your instrument here.

2.

Treble Control (Clean & Lead)

- Adjusts the high frequency response. In the full counter­clockwise position, high frequencies are bypassed to ground. In the full clockwise position, high
frequencies are allowed to pass to the next stage.

3.

Middle Control (Clean & Lead)

- 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 gain stage.

4

. Bass Control (Clean & Lead)

- 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 gain
stage.

5.

Input Gain (Clean & Lead)

- Adjusts the overall gain of the amplifier. Start with this control in

the 12 o’clock position

6.

Master Volume (Clean & Lead)

- Adjusts the output level of the clean and lead channels.

The Lead Channel can be activated by pulling the Lead Master control

.

7.

Reverb (Clean & Lead)

- The front panel reverb control is the return, or mix, control. The

reverb effect is defeated with this control in the full counter clockwise position.

8.

Boost (Clean & Lead)

- Adjusts a “Solo” option, increasing the volume of each channel. It does
not alter the gain or tone structure. These controls must be set to a level greater than the Master
Volumes to be effective.

Both Clean and Lead Boosts are Foot-Switchable and can be

activated by pulling the Boost Controls.

9.

Contour (Clean & Lead)

- The contour control is an active wide band sweep. In the 12 o’clock

position, the amps’ frequency response is flat. 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.

10.

Stand-by Switch

- Should be in the “down” or “stand-by” position when you apply power to the
