Seller's description

From Earthquaker Devices: "This all-analog tube preamplifier brings together EarthQuaker Devices’ innovative pedal design and Dr. Z Amplification’s decades of tube amp expertise. With a passive three-band EQ, professional headphone output, balanced XLR output, and onboard analog cabinet simulation, the ZEQD-Pre delivers authentic tube warmth and dynamic response in a complete analog amplifier system that fits right on your pedalboard." Specs: Boost: Use the Boost rotary knob for volume control when the Boost is active and the tone controls are bypassed. Boost mode is very loud! Be careful when setting the Boost level, especially when using headphones or XLR out. Boost Footswitch: This footswitch defeats the tone controls and delivers a full-range boost without altering the frequency response. This switch is only active when the Activate footswitch is on. Headphone Output: A TRS (Stereo) ¼” headphone jack is located on the left side. Use the Level control to adjust headphone level when the pedal is active. The headphone output works as a unity gain amplifier with cabinet simulation even when the pedal is bypassed. Direct Output: A balanced XLR output is located on the left side of the pedal. Ground Lift Switch: Press this switch on the left side of the pedal for ground lift on the XLR output. Cab Sim Bypass Switch: Press this switch on the left side of the pedal to remove the analog cabinet simulation on the XLR output. Level: Use the Level rotary knob to adjust the output volume when the tone controls are active. Bass: Use the Bass rotary knob to adjust the frequency range from 20 Hz to 400 Hz. Middle: Use the Middle rotary knob to adjust the frequency range from 400 Hz to 2 kHz. Treble: Use the Treble rotary knob to adjust the frequency range from 2 kHz to 20 kHz. Activate Footswitch: Use this footswitch to activate or bypass the ZEQD-Pre.
