FAST TRACK GUIDE AND SWITCH ON SEQUENCE 1. Check that the POWER switch on the rear panel is set to OFF and that the unit has the correct speaker load connected. 2. Connect the unit to an appropriate mains power point with the mains lead provided. We also recommend that the MASTER volume is turned down to zero before switch on or switch off purely to prevent any unwanted noises from being amplified loudly. - Page 4 Preamp select switch This enables the user to switch between PREAMP ONE and PREAMP TWO from the front panel. This can also be switched from the 2-way footswitch provided or by the optional 5-way foot controller. The corresponding LED will light up green for PREAMP ONE and red for PREAMP TWO. It will also light up amber if the 5-way footswitch is used and PREAMP 0NE &...
- Page 5 Preamp two This channel has been voiced primarily for overdriven tones although the overall sound produced can be altered radically depending on where the different controls are set. Using the BOOST fuction further increases the sonic capabilities. Gain This control adjusts the degree of drive in PREAMP TWO. Due to the design of the highly responsive all valve preamp this allows adjustment of the tone from clean, through crunch, to very dirty, adding the BOOST will then increase the sustain even further.

Power Switch Off/Standby/On This switches the amplifier from OFF to STANDBY mode, where only the valve filament heaters are on, to ON for actual use. This should be used correctly every time the unit is used to prevent problems with valves and to increase their life. Please refer to SWITCH ON SEQUENCE earlier in the manual. - Page 7 Jack Socket - For 2-Way Footswitch (Preamp1/2, Boost on/off) This is a stereo 1/4” jack socket for connection to the supplied two way latching footswitch, that enables the user to footswitch between preamp 1 and 2, and to operate the BOOST function remotely. This can be used as well as the optional five way foot controller if desired, however, due to the 2 way footswitch being a latching type, when switched on it will take priority over any other switch.
- Page 8 The choice of which mode to use will depend on what kind of effects unit is used and what overall effects is desired. But generally if time delay effects are used, such as delay (echo), reverb, chorus, flanging, phasing, etc., then the PARALLEL setting is usually preferred.
- Page 9 WARRANTY FORM, valves are not covered by the standard two year warranty except under certain conditions at the discretion of GIBSON. If you are in any doubt as to what you are doing refer the unit to an appropriate electronics service centre.
- Page 10 There are several methods that are used to bias valve amplifiers, the following is one of the easiest and ensures that the output valves do not draw too much current which can result in thermal runaway. To check or reset bias on currently installed valves:- 1.
- Page 11 The above values are a guideline but should be OK for most brands of valves, although the bias point for any amplifier is somewhat subjective. Increasing the values shown may improve the tone but will make the valves run hotter, whereas lower values will increase valve life and reliability.
