The legendary designer's return to Bad Cat after nearly two decades is not a reunion story, it's a statement: the Era 30 represents thirty-five years of engineering vision distilled into a single handwired point-to-point amplifier, and from the moment you power it up, the intention is unmistakable. Dressed in a custom Fawn finish with Brown Diamond grilles, this head and 1x12 cabinet pairing looks the part from across the room — classic, warm, and thoroughly purposeful, the kind of amp that tells you what it is before you plug in. The marine-grade Baltic Birch cabinetry and Pacific Transformers custom-wound transformer set are the bones of something built to last, and the convection-cooled, tube-rectified 5AR4 circuit keeps the power supply warm, alive, and breathing with the organic bloom that solid-state rectification simply cannot replicate.\u003c\/p\u003e\n\u003cp\u003e What makes the Era 30 genuinely remarkable is the pairing of its two fully independent channels — two fundamentally different preamp philosophies living in the same chassis, each voiced to its own standard of excellence. Channel one, driven by an EF86 preamp tube, delivers the three-dimensional, harmonically layered tones that made this tube design the obsession of boutique amp devotees for decades — shaped by a six-position stepped Depth control that sculpts low-end with surgical precision and a Treble control that goes further than a typical EQ. Channel two deploys a 12AX7 preamp for a tighter, punchier response with linear Bass and Treble controls that cover vintage chime through earthy, woody textures with equal authority. Both channels carry independent Gain and pre-phase inverter Volume controls for complete command over their individual character — and the included two-button footswitch lets you switch between them or combine them into something entirely its own. A Global Post-PI Master Volume, tube-buffered series effects loop, and switchable 4\/8\/16 ohm speaker outputs complete an amplifier designed for players who take their tone as seriously as Sampson took designing it. The matching 1x12 cabinet, loaded with a UK-made Celestion Bad Cat Custom speaker and built from voidless marine-grade Baltic Birch with a semi-open back, delivers focused, defined projection that pairs with the Era 30 head the way it was always meant to.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"UTF-8\"\u003e\u003cb\u003eFormat: \u003c\/b\u003e\u003cspan\u003eHead\u003c\/span\u003e\u003cb\u003e \u003c\/b\u003e\u003cbr\u003e\u003cb\u003eChannels\/Modes:\u003c\/b\u003e\u003cspan\u003e 2 Channel (Switable\/Mixable)\u003c\/span\u003e\u003cbr\u003e\u003cstrong\u003eChannels:\u003c\/strong\u003e\u003cspan\u003e EF86 Channel \/ 12AX7 Channel \u003c\/span\u003e\u003cbr\u003e\u003cstrong\u003eChannel Controls:\u003c\/strong\u003e\u003cspan\u003e Independent Gain and Pre-Phase Inverter Volume Control Per Channel, 6-Way Deep Control and Treble (EF86 Channel) Linear Bass and Treble on (12AX7 Channel) GOlbal Post-PI Master Volume\u003c\/span\u003e\u003cbr\u003e\u003cstrong\u003ePower Tube Type:\u003c\/strong\u003e\u003cspan\u003e 4x EL84\u003c\/span\u003e\u003cbr\u003e\u003cb\u003ePower Amp Details:\u003c\/b\u003e\u003cspan\u003e 30 Watts Handwired Point to Point, Custom Bad Cat Transformer Set by Pacific Transformers\u003c\/span\u003e\u003cbr\u003e\u003cb\u003ePreamp Tubes:\u003c\/b\u003e\u003cspan\u003e 3x 12AX7 \u0026amp; 1x EF86\u003c\/span\u003e\u003cbr\u003e\u003cstrong\u003eRectifier Type:\u003c\/strong\u003e\u003cspan\u003e 1 x 5AR4\u003c\/span\u003e\u003cbr\u003e\u003cstrong\u003eFan Cooled:\u003c\/strong\u003e\u003cspan\u003e Convection Cooled \u003c\/span\u003e\u003cbr\u003e\u003cstrong\u003eEffects Loop:\u003c\/strong\u003e\u003cspan\u003e Tube-Buffered (Series)\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cbr\u003e\u003cstrong\u003eSpeaker Outputs:\u003c\/strong\u003e\u003cspan\u003e 4,8,16 Ohm Switch for Speaker Outputs\u003c\/span\u003e\u003cbr\u003e\u003cb\u003eFoot Switchable Functions:\u003c\/b\u003e\u003cspan\u003e Channel, Combine\u003c\/span\u003e\u003cbr\u003e\u003cb\u003eChassis Material:\u003c\/b\u003e\u003cspan\u003e Aluminum\u003c\/span\u003e\u003cbr\u003e\u003cstrong\u003eCabinet Material:\u003c\/strong\u003e\u003cspan\u003e Marine Grade Baltic Birch\u003c\/span\u003e\u003cbr\u003e\u003cstrong\u003eDimensions:\u003c\/strong\u003e\u003cspan\u003e 10.5\" H x 20.75\" W x 10.25\" D\u003c\/span\u003e\u003cbr\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e\u003cspan\u003e 46.4Lbs\u003c\/span\u003e\u003cbr\u003e\u003cstrong\u003eAccessories:\u003c\/strong\u003e\u003cspan\u003e Slip cover Included\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHandwired Era 30 1x12 Cabinet\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cmeta charset=\"utf-8\"\u003e \u003cstrong\u003eSpeakers:\u003c\/strong\u003e UK Made Celestion Bad Cat Custom Speaker\u003cbr\u003e\u003cb\u003ePower Handling:\u003c\/b\u003e 60 Watts\u003cbr\u003e\u003cb\u003eBack:\u003c\/b\u003e Semi-Open Back\u003cbr\u003e\u003cstrong\u003eCabinet Material:\u003c\/strong\u003e Voidless Marine Grade Baltic Birch\u003cbr\u003e\u003cstrong\u003eDimensions:\u003c\/strong\u003e 19\" H x 23.75\" W x 10.25\" D\u003cbr\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 35.4Lbs\u003cbr\u003e\u003cstrong\u003eFinish:\u003c\/strong\u003e Fawn w Brown Diamond Grille\u003c\/span\u003e\u003c\/p\u003e","brand":"Bad Cat Amplifiers","offers":[{"title":"Default Title","offer_id":53524978106552,"sku":"Era30\/Fawn","price":4899.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0888\/2795\/3336\/files\/BadCat5260945_001availableatInterStellarGuitars_18c8e70c-95f0-4614-912c-f3d3cebd6218.jpg?v=1786208150","url":"https:\/\/www.interstellarguitars.com\/products\/bad-cat-mark-sampson-era-30-head-fawn-brown-diamond-grille","provider":"Interstellar Guitars","version":"1.0","type":"link"}
