This is the old sun lion.
Left side is the BEANO BOOST:
- BOOST KNOB, Volume of the Beano Boost, controls the amount of CRUNCH by driving your amp harder.
- Toggle TONE SWITCH with 3 positions. Up = Midrange, Center=Treble, Down=Low range boost.
- Circuit is hand wired just like the original version. Other Rangemaster clones use circuit boards.
- Has about the same output level ON and OFF with the BOOST knob set at 9:00. At 11:00 there is about a 10dB boost, which sounds twice as loud. At 12:00 there is a 13dB boost, and up all the way is about an 18dB boost which is nearly twice as loud as it was at 11:00.
Right side is the SUN FACE:
- VOL Knob needs no explanation. Audio taper volume pot.
- FUZZ knob : Best to keep it up or almost up all the way, and use the VOLUME knob on your guitar or the TRIMMER knob to control the amount of fuzz.
- ON/OFF power switch is standard on the FUZZ KNOB on the Sun Lion (optional on Sunface for $15).
- TRIMMER : The white knob on the circuit board (TRIM103). You can turn this one with your fingers. Normal setting is full CCW, for full full fuzz availability. This knob works the same as the VOLUME control on your guitar, which interactively cleans up the fuzz sound. So if you never use the FULL fuzz sound, use this knob as a preset for the maximum amount of fuzz that you need, instead of having to turn down your guitar every time you step on the fuzz. When this knob is turned all the way up (CCW) it is completely out of the circuit, as if it were not even there. Then the circuit is identical to an original 1968 germanium Fuzz Face.
- SUN knob: This is the knob in the center of the pedal�s SUN FACE, also called the Sun Dial. It is set by us to the �sweet spot� for the fuzz, just under 5 volts on the High transistor at about 70 degrees temperature. It is set with the mark at 12:00 on the SUN knob. You may try other settings, you can turn it down to get a stuttering, weak fuzz sound which can sometimes be useful. Or turn it up for a harder, less fuzzy sound. If you have a voltmeter, you can test the voltage so you can keep it set where you want it. Put the (+) lead to ground, one of the screw holes on the case will work. Put the (-) lead to the HIGH transitor leg closest to R23 (says VOLT-> on the picture, pointing to the correct leg). About 5 volts is best for cleaner sounds. I would not set it too high, much over 6 or 7 volts. When it is set at 4.5 to 5 volts, it is the same circuit as the original 1968 germanium fuzzface. You may find you need to turn it down (CCW) at higher temperatures, and up (CW) at lower temperatures. This BIAS adjustment allows it to work well at any temperature.
