It combines a genuine 12AX7 tube in the preamp stage with VOX's updated VET+ (Virtual Element Technology) digital modelling engine, delivering 11 amp models onboard — expandable to 20 using the free VOX Tone Room editor software. The 12AX7's role in the VT40X Classic Blue has been expanded from earlier Valvetronix generations, giving it a more significant influence over the amp's compression, warmth, and dynamic response, and producing a closer interaction between the tube's analogue behaviour and the DSP modelling layer than previous VTX models achieved.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003ciframe width=\"865\" height=\"495\" src=\"https:\/\/www.youtube.com\/embed\/U0vRYDdtIpY\" title=\"VT20X \u0026amp; VT40X Classic Blue — 25 Years of Valvetronix Tone\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003ch6 class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eAdvanced Amp Engine\u003c\/h6\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe VET+ engine models amp behaviour at the circuit component level rather than taking a snapshot of a target amp's tonal output, allowing the simulation to reproduce how the amp's character changes under different playing conditions — gain structure, bias, Class A versus Class AB operation, and the way the power section reacts to the output from the preamp. The result is that rolling back the guitar's volume, picking harder or softer, or playing with different attack all produce proportionally different responses in the modelled sound, in the same way they would with a real valve amplifier. The 8\" speaker sits in a tightly sealed cabinet with VOX's proprietary bass-reflex design for controlled, extended low-frequency depth.\u003c\/p\u003e\n\u003ch6 class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eBuilt-In Functionality\u003c\/h6\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eBuilt-in effects include two simultaneous pedal effects from four types each (Comp, Chorus, Overdrive, Distortion \/ Flanger, Phaser, Tremolo, Delay), four reverb types (Room, Spring, Hall, Plate), and noise reduction. 33 onboard programs are expandable to 60 via Tone Room. A USB port connects to Tone Room on Mac, Windows, iOS, and Android for deep preset editing and backup. An AUX input accepts external audio sources for play-along practice. A headphone output allows silent playing. A built-in tuner is accessible from the front panel. The Classic Blue finish uses a split-front cabinet design with blue grille cloth, reviving the early-2000s Valvetronix aesthetic.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch5\u003eKEY FEATURES: Vox VT40X Valvetronix 40W 8\" Hybrid Modelling Combo Amplifier (Classic Blue)\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eGenuine 12AX7 Tube Preamp:\u003c\/strong\u003e Actively integrated for authentic tube compression, sag, and dynamics.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eVET+ Modelling Engine:\u003c\/strong\u003e Circuit-level amp modelling for lifelike touch sensitivity and dynamic response.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e11 Amp Models Onboard:\u003c\/strong\u003e 20 via VOX Tone Room software.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e VOX AC30, BRIT 800, TWEED 4x10, DOUBLE REC, BOUTIQUE METAL, and more.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eBuilt-In Effects:\u003c\/strong\u003e 2 simultaneous pedal FX (8 types), 4 reverb types, noise reduction.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e33 Programs Onboard:\u003c\/strong\u003e 60 via VOX Tone Room.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eUSB Connectivity:\u003c\/strong\u003e VOX Tone Room editor for Mac, Windows, iOS, Android.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\u003cstrong\u003eBuilt-In Tuner.\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eAUX Input:\u003c\/strong\u003e For play-along practice from external devices.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eHeadphone Output:\u003c\/strong\u003e Silent practice.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\u003cstrong\u003e10\" Speaker, Sealed Bass-Reflex Cabinet.\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eClassic Blue Finish:\u003c\/strong\u003e Split-front cabinet, vintage-inspired blue grille cloth.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\u003cstrong\u003e40W RMS.\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Vox","offers":[{"title":"Default Title","offer_id":57741537542479,"sku":"VT40X-CLBL","price":258.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0891\/3344\/9551\/files\/preview_1_cd7f1a94-ab8a-48f0-805c-3b9d55202610.jpg?v=1779294795","url":"https:\/\/www.audiodirect.co.uk\/products\/vox-vt40x-valvetronix-40w-8-hybrid-modelling-combo-amplifier-classic-blue","provider":"Audio Direct","version":"1.0","type":"link"}
