Fishman Loudbox Micro Kombinasjon for akustisk-elektrisk gitar

Fishman Loudbox Micro — Portable 40W Bi-Amplified Acoustic Combo Amp

The Fishman Loudbox Micro is a compact acoustic guitar amplifier built for players who want the legendary tone without hauling a full-size combo. Weighing just over 9 lbs (4.1 kg), this lunchbox-sized amp delivers 40 watts of clean, bi-amplified power through a sealed cabinet that keeps the low end tight and focused. This model is the right choice for singer-songwriters, acoustic performers, and home-studio players who need a portable amp that can handle both guitar and vocals at the same time.

Two Channels, Real Tone Control, and Onboard Effects

What sets this combo apart from other practice amps in its class is the dual-channel architecture with fully independent signal paths. The instrument channel accepts both active and passive pickups through a 1/4-inch input and offers a 3-band EQ, a feedback-fighting Phase switch, dedicated Reverb, and a dual-function Chorus effect. The microphone channel uses an XLR input designed for dynamic mics and provides its own 2-band EQ plus a separate Reverb level, so vocals and guitar can be dialed in independently rather than fighting for the same tone stack.

Speaker Configuration and Power — Natural Tone in a Small Box

The bi-amplified design splits power between a dedicated woofer and tweeter, which is what gives the device an unusually full-range sound for a 40W practice amp. Acoustic guitars need both warm low-end body and articulate high-frequency detail to sound natural, and a single full-range driver usually compromises one for the other.

• Power: 40 W bi-amplified — enough headroom for small-room gigs and busking, with separate amp stages for low and high frequencies
• Woofer: 5.25-inch poly cone — handles the warm body and low-end weight of an acoustic guitar without sounding boxy
• For high-frequency clarity, the 0.8-inch soft dome tweeter reproduces vocal detail and the shimmer that makes acoustic instruments feel open.

Channel Layout and EQ — Sculpting Guitar and Vocals Separately

Acoustic amplification lives or dies by EQ flexibility, because every acoustic guitar and every room interacts differently with the speakers. The instrument channel's 3-band EQ (Low, Mid, High) gives players enough range to tame boomy lows, scoop muddy mids, or add presence on the top end depending on the guitar's tonewoods and pickup type. The microphone channel's 2-band EQ keeps vocal shaping fast and intuitive.

• Instrument Channel EQ: 3-band (Low, Mid, High) — covers the full tonal range needed to fit any acoustic-electric into a mix
• Microphone Channel EQ: 2-band (Low, High) — fast vocal shaping without overwhelming controls
• Phase Switch: feedback-fighting on instrument channel — flips polarity to cancel resonant feedback when a loud acoustic guitar starts to howl

Inputs, Outputs, and Connectivity — Stage, Studio, and Silent Practice

Beyond the two main channels, the unit is wired for real-world playing situations. The 3.5 mm AUX input lets a backing track or click from a phone join the mix, while the balanced XLR DI output sends the full stereo-free mix straight to a house PA or audio interface without needing an external direct box. The 3.5 mm headphone output mutes the speakers for late-night practice sessions.

• Instrument Input: 6.35 mm TS jack — accepts both active and passive acoustic pickups
• Microphone Input: XLR — designed for dynamic vocal mics in a singer-songwriter setup
• AUX Input: 3.5 mm jack — pairs with phones or media players for backing tracks
• DI Output: balanced XLR — sends the mixed signal to a PA or recording interface
• Headphone Output: 3.5 mm — silent practice by defeating the built-in speakers

Who Is It For — Singer-Songwriters, Home Studios, and Small Venues

This product is the right choice for singer-songwriters who need one amp that handles both guitar and vocals with independent tone control. It also suits home-studio players who want a reliable monitoring solution for tracking acoustic instruments, and small-venue performers who need a portable rig that can double as a personal monitor on stage. The 10-degree baffle tilt improves monitoring position when the amp sits on the floor, and the sealed cabinet design reduces unwanted resonance. At just over 9 lbs (4.1 kg) and measuring 206 mm D x 264 mm W x 242 mm H, it travels easily between home, studio, and gig.

Fishman and the Loudbox Line — Three Decades of Acoustic Amplification

The brand has spent more than three decades designing amplification and pickup systems specifically for acoustic instruments, and this series has become a reference name in the category. The device is the smallest and most affordable entry in that lineup, designed to bring the same preamp design and tone-shaping philosophy found in larger models into a portable format. Larry Fishman's reputation for building durable, road-ready acoustic electronics is part of why the brand has been trusted by performing acoustic players for years.
