Fishman Platinum Pro EQ

Overview: Fishman Platinum Pro EQ Preamp Hands-on Test

The Fishman Platinum Pro EQ is a floorboard-format preamplifier aimed at acoustic musicians seeking flexibility and reliable sound control. Priced at $289, the Platinum Pro EQ combines a five-band equalizer with sweepable midrange, a parametric notch filter, phase inverter, onboard tuner, boost function, and a balanced XLR direct output. Since its launch in late 2014, the pedal has served double bassists, acoustic guitarists, and even mandolin and ukulele players on stages and in studios across the globe. I evaluated its real-world usability, tone shaping capability, feedback suppression, and hardware design.

Core Features and Acoustic Instrument Compatibility

The Platinum Pro EQ delivers essential features for acoustic musicians who need more than basic amplification. Its preamplifier section is Class A circuitry, helping maintain a clear and noise-free signal path. The five-band EQ (with sweepable mid) provides broad sonic control: you get separate knobs for low cut, bass, sweepable mids, treble, and "brilliance" (upper treble). This section is responsive and covers the typical problem areas, especially for steel-string and nylon-string guitar, upright bass, mandolin, and banjo.

• Input trim and instrument calibration: The gain adjustment allows the Platinum Pro EQ to work well with both passive and active pickups, vital for upright bass and many boutique acoustic guitar systems.
• Five-band EQ: Low cut, bass, sweepable parametric mids, treble, and brilliance, all easily accessible on the top panel.
• Notch filter and phase invert: These two controls tackle stage feedback at the root, allowing users to dial out problem frequencies and eliminate low-end 'boom' or high-frequency squeal.
• Compressor and boost: The single-knob compressor helps control playing dynamics (especially in percussive or fingerstyle settings), while the 12 dB boost switch is tailored for soloing or cutting through a band mix. The boost level is trimmable from the chassis side.
• Onboard tuner with mute switch: Unlike pedalboard mini-tuners, this built-in model offers reasonable accuracy and clarity for standard tuning, and acts as a mute for silent tuning between songs.
• XLR direct out with ground lift and pre/post EQ selector: For connecting directly to mixing desks or PA systems.

Live Performance: Feedback Suppression and Practical Tuning

Field reports consistently praise the Platinum Pro EQ's ability to tame feedback on loud or resonant stages. Deploying the low cut removes low-frequency rumble, the parametric notch filter pinpoints and eliminates resonant frequencies, and the phase switch is effective at squashing further feedback, even with voluminous piezo pickups and in front of wedge monitors. Many users who previously struggled with feedback on amplifiers or PA systems found immediate relief after dialing these controls, with comments highlighting that the preamp "makes feedback disappear", even allowing players to perform close to their own speakers without issue.

Across instruments, the EQ is described as flexible, with enough range to rescue thin-sounding pickups or mellow out boxy, boomy lows. Musicians report "buttery smooth" tone for upright bass, enhanced definition for guitar, and a natural timbre for ukulele basses and mandolins. The adjustable boost gives acoustic soloists the volume jump they need, and the tuner, though bright and accurate in most conditions, can be hard to read in full sunlight and only operates when muted.

Construction, Ergonomics, and Power Supply

The enclosure combines substantial metal and plastic elements. While the faceplate and switches are robust, the sides and battery compartment are plastic; some users mention concerns about longevity and would have preferred an all-metal chassis. The pedal is notably compact considering how many features it packs, and rotary knobs are well-spaced with a positive, rugged feel (even though some wish the EQ frequencies were labeled with exact values).

Battery access is via a bottom lid, functional but a bit flimsy according to long-term owners. Power comes from a standard 9V battery or optional adapter (not included); battery life is typical for this class, but a few report better performance using high-quality cells versus external adapters, which may introduce unwanted hum.

Limitations: Noise, Controls, and Output Behavior

• Noise on high treble or post-EQ XLR: Some users report noticeable hiss when treble or brilliance controls are set aggressively, and a few experienced noise at the post-EQ direct output in certain installations.
• Limited parameter labeling and accessibility: Not all controls are easily adjusted on the fly, the boost and input trim trimmers are recessed to avoid accidental changes, but this also makes quick tweaks inconvenient for musicians switching instruments mid-set.
• Output level management: The general volume (level) knob only controls the quarter-inch jack output, not the XLR DI out. This means users running both lines must balance level at the desk, not from the pedal (the boost switch does affect the XLR if it's set to post-EQ).
• Not a full effects unit: Those expecting built-in reverb, chorus, or amp modeling will not find such features here; it's a pure preamp-EQ-tuner unit.

Who Is the Fishman Platinum Pro EQ For?

Acoustic musicians demanding precise tone control, robust feedback management, and a reliable direct interface for stage and studio will find the Platinum Pro EQ a well-designed tool. The compressor, mute/tune function, and sweepable EQ make it a Swiss Army knife for live acoustic setups, from double bass and cello to steel-string guitar, ukulele bass, and folk instruments. For musicians seeking amp-style warmth or saturation, pedals with tube simulation or saturation will offer a different flavor, but for clarity, control, and flexibility, the Fishman holds its ground.

Long-term reliability is generally solid, with reports of some early units failing or experiencing noise, but customer service appears responsive in handling returns and replacements.

Conclusion: Professional Utility for Stage and Studio

The Fishman Platinum Pro EQ stands out as a comprehensive solution for acoustic players who demand more than basic plug-and-play, delivering clean signal, configurable EQ, powerful feedback controls, and gig-friendly features in a portable format. While not perfect (plastic side panels, battery drawer, some parameter accessibility quirks), its tonal shaping and feedback suppression capabilities more than justify the price for serious performers. For those ready to invest in a central pedal for their acoustic board, Fishman's Platinum Pro EQ remains a top contender.
