nels; Gain 1’s pull switch must be pushed in for the FS-7 to choose channels. See info on the FS-7 and

its functions.)

Low Gain input This is a low-sensitivity input. Guitars plugged into it have

more headroom before distortion sets in (meaning that you can crank up a chan-

nel’s volume a little louder before you experience preamp distortion). This is a

good choice for a clean overall sound, and is especially well-suited to active pick-

ups or guitars equipped with preamps.

High Gain input This is a high-sensitivity input. If your guitar has hot pickups, then plugging into

it makes it easy to overdrive the preamp section, creating harmonic distortion. Guitars equipped with

low-output pickups seem hotter than usual when plugged into this input.

Mains Input

Your KnuckleHead II has a detachable power cord that connects to the chassis AC connector labeled

Mains Input. Always use this cord and, in the event that the power cord requires replacement, replace it

with the same type of power cord. Consult your RIVERA dealer for further information. Be sure to use

a grounded electrical mains power supply socket whenever possible. These outlets have a grounding pin

in addition to the nor-

mal line and neutral

pin. The power cord

supplied with your

KnuckleHead II has a

3-pin plug. Do not cut

off or damage the

ground pin. If the

available electrical outlet is of the older 2-pin type, use a suitable ground-lift adapter.

The U.S.A., Canada, and Japan share a common CSA/UL-style cord. Most of Europe and Scandinavia

utilize a Euro plug and have a SEMKO/VDE-style cord. Australia uses a different type of plug, as does

England.

Note: Avoid using long extension cords. Long cords have sufficient resistance to electrical current that the

voltage arriving at your amp can be significantly reduced. This can have a bad effect on your tone.

Mains Fuse

This AC line fuse protects your amplifier from damage due to shorts, momentary surges, and defective power tubes.

In the event of a fuse failure, always replace it with the same type of fuse.

Note: Always turn the amp off and wait about five minutes before replacing a fuse. This allows the

parts to cool and high voltages to dissipate.

For 100VAC versions, the Mains Fuse is: 5 Amp, 250 Volt Slo-Blo type (size 3AG, or MDL)

For 115VAC versions, the Mains Fuse is: 4 Amp, 250 Volt Slo-Blo type (size 3AG, or MDL)

For 230VAC versions, the Mains Fuse is: T 2A (time-delay, 5mm x 20mm size)
