TURF OVERDRIVE CHANNEL
0Valves need to reach a specific operating temperature, which means that it takes a few seconds after switching on before they are ready for use.
•Valves are sensitive to shock. Allow the unit to cool off for a few minutes
before moving it.
0The sound characteristics of valves do lend to change with age. You should exchange your valves occasionally; the ECC 83 tubes used in the Sixty are amongst the most frequently used and affordable types available. In normal use, it should only be necessary to change the valves every few years.
(5)GAIN:
Adjusts the input sensivity of the TUBE circuitry and thereby the saturation. At lower GAIN levels, you can achieve bluesy Clean and Crunch sounds.
In the specially marked high level section an automatic MID BOOST gets effective, perfect for modern “hot rodded” Overdrive sounds.
The GAIN control influences the overdrive characteristics as well as the volume of the TUBE OVERDRIVE channel. To alter the level, use the VOLUME control.
The TONE CONTROLS on the TUBE OVERDRIVE channel are active in operation, and can therefore be used to boost specific frequency ranges. This can be very useful for producing modern “hot rodded” distortion sounds. The filter characteristics of the two controls are chosen so as to make selection of the distinctive “creamy” lead and riff sounds easier.
(6)VOICE:
Voice adjusts a wide range of lower mids and thus controls the overdrive characteristic. More “Voice” will make your guitar sound more “creamy”.
(7)BITE:
Bite controls the upper harmonics and the penetration of the guitar sound.
(8)VOLUME:
VOLUME adjusts the output volume of the TUBE OVERDRIVE and thus the volume balance between CLEAN and OVERDRIVE.
