FRONT PANEL: Controls & Features (Continued)

OUTPUT & SOLO CONTROLS: (Continued) SOLO: This control can only be activated if the correct Footswitch is connected SOLO is an additional fi nal output level control wired in parallel with the OUTPUT control. It is capable

	of a setting above that of the OUTPUT control and can not be set below. The amount
100 W	of apparent boost also depends on that of the OUTPUT control - in that if the amplifi er
	is at either the extreme low or extreme high levels of the OUTPUT, its effectiveness is

50 W	minimized. It has been optimized for live performance volume levels.
MASTER
100 W	If the power section is either not a part of the sound (super quiet), or producing all its
50 W	rated wattage (super loud), there is very little signal for the SOLO control to work with. By
	using the Footswitch and selecting SOLO , a pre-settable boost in overall levels is possible
	on the fl y...giving you some control over your levels when it’s time to step out. Engineers

may give you a bit of a frown the fi rst time you use it...but isn’t it time you heard yourself. It might even prevent them from punishing you with the dreaded monitor or sidefi ll version of your tone.

POWER: TWEED / OFF / ON This sideways 3 position toggle switch determines the status of the incoming AC power. Your LONE STAR incorporates a built-in VARIAC feature that enables you to reduce the line voltage to approximately 93 volts (with a steady 117 at the wall).This TWEED power setting produces a spongier, scoopier response and allows you to power clip the amplifi er at lower overall volumes. It is especially useful in achieving old school clip sounds in Channel 1 and Channel

	2 with the DRIVE bypassed.
TWEED	ON
POWER OFF	These sounds are further enhanced when the TWEED power feature is used in combination with the 50 watt
STANDBY	setting and TUBE RECTIFIER:TRACKING is selected. Another bonus is that if you were to use the TWEED
	power setting often, tube life would increase substantially.
	ON

For maximum power, normal response and the greatest headroom use the ON setting of the AC power switch.

STANDBY: Perfect for set breaks... this toggle switch also serves an even more important purpose. In the Standby position the tubes are at idle so that during power up they may warm up before being put to use. Before Power is switched on make sure the STANDBY switch is in the Standby position.

TWEED ON POWER OFF

STANDBY

ON

Wait at least 30 seconds and then fl ip the STANDBY switch to the ON position. This prevents tube problems and increases their toneful life substantially.

Now that we have reviewed the features and controls of the Front Panel and you have a handle on how they interact to achieve the sound you want, let’s move to the Rear Panel and cover the features found there.
