Page 3: Front Panel Functions
Front Panel Functions Input Jack- High impedance input to the amplifier. Plug in your instrument here. Treble - 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 Gain - Adjusts the overall gain of the amplifier. Start with this control in the 12 o’clock position then adjust to taste. This control determines the initial character of your tone, from cleaner/brighter tones at low settings to fatter/warmer tones at higher settings. As you turn this control up it also introduces more gain and bass into the signal path, and reduces the amount of available clean headroom especially when the master volume is set higher.
- Page 5 Clean Reverb Send - The reverb send control determines the amount of signal applied to the reverb tank. Low settings will create short decay times. Advancing the control clockwise increases the signal applied to the tank for longer decay times. Clean Reverb Return - This is the reverb return control which mixes the reverb effect signal with the dry signal.

Effects Loop – The effects loop on this amplifier is a passive type of loop, see FAQ on two-rock.com Pre-Amp Out - Use this jack to send the amplifier’s signal to the effects that you want to use in the loop. - Page 7 Overdrive Reverb Send - This control determines the amount of overdrive channel 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.

Page 9: Bias Procedure
Each fine production tube is tested and matched to our exacting specifications. When the time comes that the power tubes need replacing, it’s very important to use high quality, matched sets of power tubes. It’s also critical that the bias of the amp be reset after installing new, or NOS power tubes. - Page 10 We know your new Two-Rock amplifier will provide many hours of enjoyment and inspiration in the years to come.
