• True bypass
• Independent boost with level adjust
• Master Controls: Gain, Volume, Tone and Channel Blend
• Channel Blend simulates the two channels of a 4 input 67-69 plexi amplifier.  Turn all the way left at "100%" for the brighter channel “T” only, turn all the way right at “100%” for the normal channel “B” only.   Place the knob in the middle at "50/50” for a equal mix of both channels.  The "50/50" position has the same effect as jumping the two channels of your British amplifier with a cable. Ultimately the Ch. blend lets you mix the two channel at any ratio you like.
• Variac On/Off switch:  adds a “dropped voltage” dynamic compression to the feel and sound for that illusive Brown sound
• Gain  Switch: Low, Medium and High gain levels
• Presence Switch: "h" is high, for a more open and bright tone.  "L" is low for a more rounder tone with milder high frequencies
• Structure Switch: The smaller black dot refers to a tight and focused gain structure.  The open circle delivers a loose and fat gain structure.  The solid large black dot refers to a gain structure in between the other two extremes.
• Jacks: input, output and exp. The expression pedal input lets you connect the output of a  volume pedal which can control the gain of the LaGrange.
• Low Battery Indicator: LEDs blink when battery voltage drops below critical threshold.
