Markbass Little Mark Tube Bass Amp Head 500W

The Pure Hybrid Solution: Markbass Little Mark Tube Bass Amplifier Head

For gigging professionals and active session bassists, finding an amplifier that can effortlessly bridge the gap between distinct musical genres can be a challenge. Modern solid-state heads offer a brilliant, lightning-fast transient snap that is perfect for modern funk, while classic tube configurations inject that pillowy, harmonic-rich warmth required for vintage rock and soul. The Markbass Little Mark Tube amplifier head elegant resolves this dilemma. Delivering 500 watts of high-headroom power into a highly portable frame, this premium hybrid head incorporates a clever dual preamplifier configuration that allows you to seamlessly blend between solid-state clarity and tube fatness. If you want absolute authority over your sonic texture without carrying multiple heavy rigs to the gig, this is your definitive stage tool.

The Art of the Blend: Dual Solid-State and Tube Preamps

The core innovation of the Little Mark Tube is its parallel dual-preamp architecture. On the front control panel, you will find a specialized solid-state preamplifier alongside a warm, organic analog preamp driven by a premium ECC83 (12AX7) vacuum tube. Instead of forcing you to toggle rigidly between the two, Markbass incorporates a specialized "Mix" control dial. This lets you continuously blend the two circuits together to voice your ideal tone. Dial it fully to the left for a ultra-clean, transparent solid-state response; twist it completely to the right to saturate your signal with beautiful even-order harmonics and natural tube compression; or place it anywhere in the middle to experience a rich, punchy hybrid tone that brings out the best of both analog worlds.

Legendary Markbass Filtering and Tone Sculpting

To help you quickly adapt to unpredictable room acoustics, the front control layout features a highly precise, musical 4-band equalizer (Low, Mid-Low, Mid-High, High) capable of up to 16 dB of boost or cut. Alongside the standard EQ, the head incorporates Markbass's world-renowned signature tone-shaping filters:

VLE (Vintage Loudspeaker Emulator): Gradually cuts high frequencies (ranging from 250 Hz to 20 kHz) to beautifully emulate the dark, round, organic character of old-school passive cabinets—the ultimate preset for classic Motown, reggae, and retro rock grooves.
VPF (Variable Preshape Filter): An advanced contour filter that scoops out mid-range frequencies centered around 380 Hz while boosting low-end body and high-end sparkle, instantly dialing in a pristine, glassy profile ideal for modern slap-and-pop techniques.

Pro-Grade Architecture and Smart Live Performance Routing

The Little Mark Tube is meticulously engineered to streamline your life on the road. For fast instrument changes and silent tuning on dark stages, the master volume knob features a smart pull-to-mute function, allowing you to mute your entire live rig without changing your carefully dialed gain structure. For studio recording engineers and live front-of-house technicians, the rear panel includes a premium Balanced XLR Line Out driven by an independent level control dial, complete with handy pre/post EQ and ground-lift toggle switches to guarantee a flawless, noise-free direct feed straight to the mixing console.

Uncompromised Power Handling in a Lightweight Frame

Pushing a continuous 500 watts of raw power into a 4-Ohm load, this amplifier head possesses exceptional energy reserves. Your lowest frequencies—even when handling a low-B string on active 5- or 6-string basses—retain immense physical weight and definition without choking or clipping prematurely under heavy attacks. Wrapped in a rugged, road-ready metal chassis and weighing a mere 2.3 kg (5.07 lbs), it slides effortlessly into a backpack or gig bag pocket, offering an effortless, back-saving transport experience.
