Handcrafted in Athens, Greece, JAM Pedals engineered the mk.2 to deliver a warm, rich, and naturally articulate overdrive that completely bypasses the harsh, congested midrange honk associated with generic tube-screamer clones. By pairing foundational vintage architecture with modern, performance-driven switching, the mk.2 redefines what a boutique overdrive pedal can achieve on a professional signal chain.\u003c\/p\u003e\n\n\u003cp\u003eAt the center of the Tubedreamer’s signal path is the legendary, new-old-stock \u003cstrong\u003eJRC4558D operational amplifier\u003c\/strong\u003e chip—the same component driving the most coveted vintage units from the late 1970s and early '80s. JAM Pedals combines this historic chip with improved low-gain resolution, providing finer micro-control over your core grit and unlocking a much wider array of touch-sensitive clean-boost and light breakup textures at the bottom end of the gain sweep.\u003c\/p\u003e\n\n\u003ch3\u003eAsymmetrical Clipping vs. No-Diode Dynamic Modes\u003c\/h3\u003e\n\u003cp\u003eThe mk.2 introduces an exceptionally interactive two-way clipping toggle that drastically alters the pedal's compression and clipping behavior:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAsymmetrical Clipping:\u003c\/strong\u003e Uses a specialized 3-diode layout that introduces an uneven clipping threshold. This replicates the complex, touch-sensitive breakup of an overdriven tube amplifier power section, responding dynamically to your picking velocity and guitar volume adjustments.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNo-Diode Mode (N):\u003c\/strong\u003e Completely removes the clipping diodes from the circuit. This shifts the pedal into a wide-open, highly linear operational amplifier boost, providing maximum clean headroom, crisp transient delivery, and an uncompressed, amp-like response.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eDual-Channel Utility with Dual Internal Trimmers\u003c\/h3\u003e\n\u003cp\u003eFor the first time in the Tubedreamer’s history, the high-gain boost stage is fully accessible via an independent, secondary footswitch, turning the pedal into a true two-channel dirt box. To ensure complete control over your stage levels, JAM Pedals integrated \u003cstrong\u003edual internal trimmers\u003c\/strong\u003e. These allow you to set an independent output volume specifically for the high-gain mode across both clipping options—allowing you to dial in either a perfectly unity-volume gain jump or a massive, soaring solo boost.\u003c\/p\u003e\n\n\u003ch3\u003eBoutique Direct Utility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSelectable Power-On State:\u003c\/strong\u003e A smart utility feature allows you to program the pedal’s internal memory to either immediately engage or remain completely bypassed upon receiving power on your board.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBoutique Enclosure:\u003c\/strong\u003e Housed in JAM Pedals’ signature, hand-painted enclosure, giving every single pedal a unique aesthetic finish while utilizing premium, tour-grade components.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrue Bypass Signal Integrity:\u003c\/strong\u003e Equipped with a mechanical true bypass switch to ensure your clean instrument signal passes through completely uncolored when the effect is disengaged.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTech Specs\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePedal Type:\u003c\/strong\u003e Professional 808-Style Overdrive \/ Dual-Channel Boost\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCore Component:\u003c\/strong\u003e Legendary JRC4558D Op-Amp Chip\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eControls:\u003c\/strong\u003e Level, Tone, Gain, 2-Way Clipping Toggle (Asymmetrical \/ No-Diode)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFootswitches:\u003c\/strong\u003e Bypass, High-Gain Stage Engage\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInput Impedance:\u003c\/strong\u003e 500 kΩ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutput Impedance:\u003c\/strong\u003e Less than 5 kΩ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower Requirement:\u003c\/strong\u003e 9V DC (Center Negative, ~60mA current draw)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 2.9\" x 4.7\" x 2.2\" (7.5cm x 12.0cm x 5.6cm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e Handbuilt and Hand-Painted in Athens, Greece\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JAM Pedals","offers":[{"title":"Default Title","offer_id":55450069336356,"sku":"2700","price":279.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0830\/6733\/9044\/files\/jam-tubedreamer-mk2-overdrive-pedal-3.jpg?v=1782770321","url":"https:\/\/tonewolf.com\/products\/jam-tubedreamer-mk2-overdrive-pedal","provider":"Tone Wolf","version":"1.0","type":"link"}
