to your amplifier.
4. Output Impedance Selector: set this selector according to the appropriate speaker
impedance you are using. 4, 8, and 16 Ohm settings are available.
5. Output Jacks: two, standard ¼ inch speaker jacks, wired parallel, which will
accommodate any quality standard speaker cable. Note: never use a shielded guitar cable
as a speaker cable. You can severely damage an amplifier.
6. Tube Chart: displays the placement of the power and pre amp tubes
7. Fast / Gradual: switch enables the musician to alter the response characteristics of the
amplifier to suit their playing style. A simple flip of the switch lets you choose between
two different responses to your picking dynamics and guitar's volume control settings.
This is not an extra gain stage or gain boost circuit. Instead it functions by magnifying
subtle changes in pick or finger attack along with subtle changes in guitar volume. The
Gradual setting of the circuit allows a clean player to run the full range of dynamics
without breaking into unwanted distortion. You can play on the edge of distortion easily
going from clean to blues overdrive using pick attack as the controlling factor. An over
the top player can go from clean to scorch using the Fast setting. The slightest change in
pick attack or guitar volume setting will translate to huge changes in dynamics and
power. To sum it up, this function lets you choose the response and feel you want and
makes your amplifier capable of playing every style of music desired.
Note: you will hear a "
