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.
Front Panel Functions 1. Input Jack- High impedance input to the amplifier. Plug in your instrument here. 2. 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.
12. Reverb Send- The reverb drive control determines the amount of signal applied to the reverb tank. Low settings 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.
7. Effects Return- Use this jack to connect the output of your effects to the amplifier. 8. Traditional / Modern- This switch affects the internal negative feedback circuit located in the preamp section. The effect is subtle and becomes more apparent as you familiarize yourself with various settings. “The Modern settings is our standard Two-rock negative feedback circuit, it is most effective when using high output humbucking or active pickups.
