Packed with a massive array of nine 12AX7 preamp tubes, this unit offers four distinct channels ranging from sparkling, pristine cleans to thick, high-gain lead distortion. Beyond its tube-driven core, it features an impressive suite of tone-shaping tools, including a 5-band graphic EQ, built-in spring reverb, an adjustable noise gate, and flexible stereo effects loops with MIDI switching. Whether used for direct recording with its cabinet-simulated outputs or paired with a stereo power amp for live performances, the Quad X-Amp remains a highly capable cult classic for players seeking authentic 90s tube warmth and versatile tone sculpting.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/b\u003e\u003cbr\u003eThis Early 1990s Carvin Quad X-Amp Stereo Tube Guitar Preamp is in Excellent condition, part of a single-owner, climate controlled collection, with extremely light wear consistent with age and only the most occasional home use.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e\u003cstrong\u003eAll instruments from Music Makers are professionally evaluated and set-up in our historic Galesburg, IL. storefront prior to shipping.\u003c\/strong\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ci\u003e\u003cb\u003e\u003cstrong\u003eQuestions?
