Page 2: Dear Customer
Dear Customer, Thank you for your purchase of a Two-Rock amplifier from Two-Rock Amplifiers, LLC. 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. - Page 3 INPUT - High impedance input to the amplifier. Plug in your instrument here. TREBLE + Push/Pull BRIGHT - Adjusts the high frequency response. At lower settings of this control the tone will be warmer and smoother. As you turn this control up the highs become more prominent and aggressive adding gain to the signal as well.
- Page 4 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 increasing the volume of the amplifier.

Effects Loop – The effects loop on this amplifier is a “half active” type of loop, see FAQ on two-rock.com SEND - Use this jack to send the amplifier’s signal to the effects that you want to use in the loop. - Page 6 PICKUP LOADING - Loading the guitar pickup(s) to varying degrees changes the impedance relationship between the pickup and the amplifier’s first gain stage. Loading reduces inductive “ringing” in the pickup coils. The result is a more controlled high frequency response and a reduction in high frequency artifacts produced when a pickup’s magnets and coils feedback with each other, usually at or near the pickup’s saturation point.
