BRIGHT:
Engaging this switch boosts the upper mid frequencies, which adds clarity and definition to your tone which is useful for a variety of percussive playing styles such as Funk, Rock, and R&B.

MID:
Engaging this switch boosts the lower mid frequencies, which thickens up your overdriven rhythm and lead tones.

GAIN:
Engaging this switch adds 12dB of gain, which increases sustain and emphasizes upper harmonics for singing solos and percussive Alternative style rhythm playing.

PRESENCE:
Engaging this switch boosts the midrange frequencies, which gives your tone better definition and a clarity, without sounding harsh or fatiguing.

DEEP:
Engaging this switch boosts the bottom-end, adding low-end thump and body to any style, from clean to heavily distorted. This switch can also be used to compensate for a loss of low-end/body when playing Corso at lower volumes.

DRIVE:
Adjusts the amount of pre-amp overdrive added to your signal. Use the Drive control in conjunction with the Gain switch to experience the wide range of tones that Corso has to offer.

• Clean: settings between 1-2 offer a variety of full bodied clean tones with excellent clarity
• Classic Crunch: settings between 3-4 (with gain switch in the on position) offer a variety of British crunch rhythm tones with excellent midrange cut and articulation
• High Gain: settings between 5-7 (with gain switch in the on position) offer a dramatic increase in gain with extended low-end thump without loss of definition – taking you from Hard Rock to 80’s Heavy Metal
• Metal/Alternative (Alt) Tuning: settings between 8 and higher (with gain switch in the on position) offer increased saturation, harmonics (for additional sustain) and low end emphasis when playing drop and alt tuning styles

TREBLE:
Turning the control clockwise emphasizes the upper frequencies. While turning the control counter clockwise produces a warmer sound, which is excellent for dialing in smoother fluid-like lead tones, and is also well suited for Jazz styles.

BASS:
Turning the control clockwise increases the lower frequencies, providing a fuller low-end response. While turning the control counter clockwise reduces the bass, which tightens up the bottom-end. This can be very useful when playing at louder volumes, and at higher gain settings.

POWER:
A volume control that adjusts the overall output of your signal. Fully counter-clockwise (0) the Power control acts as a Load, allowing you to take complete advantage of Corso’s Line Out without having to be connected to a speaker cabinet.

NOTE: The Power control only affects Corso’s speaker outputs, this does not alter/change the output level of the Line Out.
