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\u003cb\u003e\u003cstrong\u003ePractice Amp with Headphones\u003c\/strong\u003e\u003c\/b\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\u003cb\u003e\u003cstrong\u003eDirect Amplifier via XLR\u003c\/strong\u003e\u003c\/b\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\u003cb\u003e\u003cstrong\u003eFlexible Routing\u003c\/strong\u003e\u003c\/b\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\u003cb\u003e\u003cstrong\u003eWhy The EF86 Tube?\u003c\/strong\u003e\u003c\/b\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\u003cb\u003e\u003cstrong\u003eThe Technical Side\u003c\/strong\u003e\u003c\/b\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\u003cb\u003e\u003cstrong\u003eWhat This Means for You\u003c\/strong\u003e\u003c\/b\u003e\u003cbr\u003eThese specifications translate directly to playing experience:\u003c\/p\u003e\u003cp\u003eTouch Sensitivity: The EF86 responds to every dynamic nuance in your playing. Play lighter and it cleans up; dig in and it blooms. Natural expression that follows your hands.\u003c\/p\u003e\u003cp\u003eFull-Frequency Clarity: Extended response means harmonic richness without sacrificing definition. Bass notes stay tight, highs remain bell-like and clear.\u003c\/p\u003e\u003cp\u003eResponsive EQ: Higher voltage and broader bandwidth let the passive Three-Band EQ shape your tone effectively with minimal signal loss. The interactive controls behave like classic tube amp tone stacks—predictable and musical across their entire sweep.\u003c\/p\u003e\u003cp\u003eThe EF86 brings hi-fi performance to tube preamplification while staying responsive and musical.\u003c\/p\u003e\u003cp\u003e\u003cb\u003e\u003cstrong\u003eControls\u003c\/strong\u003e\u003c\/b\u003e\u003cbr\u003eBoost: 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.\u003c\/p\u003e\u003cp\u003eBoost 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.\u003c\/p\u003e\u003cp\u003eHeadphone 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.\u003c\/p\u003e\u003cp\u003eDirect Output: A balanced XLR output is located on the left side of the pedal.\u003c\/p\u003e\u003cp\u003eGround Lift Switch: Press this switch on the left side of the pedal for ground lift on the XLR output.\u003c\/p\u003e\u003cp\u003eCab Sim Bypass Switch: Press this switch on the left side of the pedal to remove the analog cabinet simulation on the XLR output.\u003c\/p\u003e\u003cp\u003eLevel: Use the Level rotary knob to adjust the output volume when the tone controls are active.\u003c\/p\u003e\u003cp\u003eBass: Use the Bass rotary knob to adjust the frequency range from 20 Hz to 400 Hz.\u003c\/p\u003e\u003cp\u003eMiddle: Use the Middle rotary knob to adjust the frequency range from 400 Hz to 2 kHz.\u003c\/p\u003e\u003cp\u003eTreble: Use the Treble rotary knob to adjust the frequency range from 2 kHz to 20 kHz.\u003c\/p\u003e\u003cp\u003eActivate Footswitch: Use this footswitch to activate or bypass the ZEQD-Pre.\u003c\/p\u003e\u003cp\u003e\u003cb\u003e\u003cstrong\u003eTech Specs\u003c\/strong\u003e\u003c\/b\u003e\u003cbr\u003eDimensions: 5.88 x 3.94 x 2.75 in.

We always recommend pedal-specific, transformer-isolated wall-wart power supplies or multiple isolated-output supplies. Pedals will make extra noise if there is ripple or unclean power. Switching-type power supplies, daisy chains, and non-pedal specific power supplies do not filter dirty power as well and let through unwanted noise. DO NOT RUN AT HIGHER VOLTAGES!\u003c\/p\u003e","brand":"EarthQuaker Devices","offers":[{"title":"Default Title","offer_id":53054471176481,"sku":"ACEARZEQD","price":399.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0993\/7862\/6849\/files\/157cc40b-26ff-4d94-b9f3-dd79cba74c0b.jpg?v=1784567147","url":"https:\/\/citymusiconline.com\/products\/earthquaker-zeqd-pre-preamp","provider":"City Music Online","version":"1.0","type":"link"}
