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.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePractice Amp with Headphones\u003c\/strong\u003e\u003cbr\u003eThe headphone output features built-in analog cabinet simulation for a realistic amp feel during quiet practice sessions. Enjoy the full EF86 tube character without disturbing your housemates.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDirect Amplifier via XLR\u003c\/strong\u003e\u003cbr\u003eRun the balanced XLR output straight into any console or interface and use the ZEQD-Pre as your main amp. The analog cabinet simulation is there when you need it, or flip the Cab Bypass switch to send a pure signal to your preferred IR loader or modeling software. Perfect for direct recording, backline-free gigs, or hybrid rigs with multiple signal paths.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFlexible Routing\u003c\/strong\u003e\u003cbr\u003eAll outputs work simultaneously, even when the pedal is bypassed. Send your signal to an amp, route a direct feed to front-of-house, and monitor through headphones all at once. This routing flexibility makes the ZEQD-Pre an invaluable studio tool.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy The EF86 Tube?\u003c\/strong\u003e\u003cbr\u003eThe ZEQD-Pre uses the EF86 pentode, the same tube that gives many Dr. Z amplifiers their pristine hi-fi tone and makes them such responsive pedal platforms.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe Technical Side\u003c\/strong\u003e\u003cbr\u003eUnlike the common 12AX7 triode (two elements plus cathode), the EF86 pentode has four internal elements plus cathode. This structure yields measurably superior performance:\u003cbr\u003eGain Factor of 185: Significantly higher than comparable triodes\u003cbr\u003e44V RMS Output: Substantial voltage swing for enhanced dynamics\u003cbr\u003eExtended Frequency Response: Full-spectrum clarity from deep lows to detailed highs\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eControls\u003c\/strong\u003e\u003cbr\u003eBoost: Volume control when the Boost is active and the tone controls are bypassed. Boost mode is very loud!\u003cbr\u003eBoost Footswitch: Defeats the tone controls and delivers a full-range boost without altering the frequency response.\u003cbr\u003eHeadphone Output: A TRS (Stereo) 1\/4\" headphone jack with cabinet simulation, active even when the pedal is bypassed.\u003cbr\u003eDirect Output: A balanced XLR output.\u003cbr\u003eGround Lift Switch: Ground lift on the XLR output.\u003cbr\u003eCab Sim Bypass Switch: Removes the analog cabinet simulation on the XLR output.\u003cbr\u003eLevel: Adjusts the output volume when the tone controls are active.\u003cbr\u003eBass: 20 Hz to 400 Hz.\u003cbr\u003eMiddle: 400 Hz to 2 kHz.\u003cbr\u003eTreble: 2 kHz to 20 kHz.\u003cbr\u003eActivate Footswitch: Activates or bypasses the ZEQD-Pre.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTech Specs\u003c\/strong\u003e\u003cbr\u003eDimensions: 5.88 x 3.94 x 2.75 in.
