Designed by noted amp builder James Brown, the 100W Double Cross boldly redefines high-gain guitar amplification with a broad spectrum of stunning tones and user-modified features.The Double Cross amp head has three distinctively voiced channels: Rhythm, Lead I and Lead II. Each Lead channel can be modified by users via four separate function switches which are located at the four end points of a cross design on the control panel. These switches are not simply EQ parameters; each uniquely blends additional 12AX7 tube stages, letting players actually alter the Gain/EQ/Attack structure of their preamps modifications usually not offered to consumers unless they take their amplifier to a knowledgeable technician to be permanently "modded."The two Lead channels are voiced differently, with Lead I catering to a modern, heavy tone and Lead II crafted for a more traditional, high-gain "cranked amp" lead tone.The four switches on each Cross are: (1) Bright: alters the tone to enhance high-end response and tighten the low-end(2) Gain: boosts the preamp gain (3) Tight Stage: adds chunky, vintage-style gain like a classic amp when fully cranked (4) Thick Stage: offers rich, aggressive tonal qualities with complex harmonic content. These four functions may be activated, omitted and blended in any combination to create a fantastically wide choice of tones.Adding more gain usually causes so much compression that you lose dynamics and note definition. Although the Double Cross offers tremendous amounts of gain and distortion, it adds the extra tubes in a way that doesn't change your dynamics or sacrifice the touch sensitivity, regardless of the amp's settings.All three channels of the Double Cross provide separate Gain & Volume controls a standard Kustom feature as well as independent Bass, Middle, Treble and Presence controls. There is also a global Master Volume and a Boost Volume control that can be activated with the Double Cross's 5-function metal footswitch (included).A speaker cabinet-emulated Direct Out, drawn from Kustom's Coupe 1/2 Series amplifiers, has evolved to offer two signal options: (1) the tonal coloration provided by a Slant-style 4x12 cabinet or (2) The distinct sound of a straight-style 4x12. The rich, punchy tone of Kustom's D.I. signal is revered by professional musicians and is now even better.Special features include an all-tube, footswitchable effects loop, a 6L5 / #EL34 bias switch for changing output tube types, a Tight input jack that tightens the attack response of the entire amplifier, and a 5-function footswitch that activates each channel, the Boost function, and the effects loop.
