About this listing
Electronic Audio Experiments Surveyor Instrument Voicing Preamp Pedal | No Limit Guitar Co, Idaho FallsThe Electronic Audio Experiments Surveyor is a compact reimagining of the legendary Instrument Voicing Preamp (IVP), a cult classic rackmount preamplifier long prized for its distinctively clangy, harmonically aggressive character. Built around a unique transformer-loaded "Tube Voice" distortion engine with pre-clipping EQ, the Surveyor gives players precise, frequency-selective saturation that goes far beyond what a standard drive pedal can offer. Whether you play guitar, bass, synthesizer, or beyond, this is a remarkably versatile tool available now at No Limit Guitar Co in Idaho Falls.Product Overview The Surveyor's defining design philosophy sets it apart from virtually every other drive pedal on the market: its two-band shelving EQ is placed before the clipping stage rather than after. This means that gain is applied selectively to the frequencies you choose — boost the treble shelf for the IVP's signature clangy attack, or push the bass shelf into fuzz territory for thick, overloaded low-end saturation. The result is a palette of saturated textures that is highly responsive to your instrument's frequency content and playing dynamics.At the heart of the circuit is a transformer-loaded solid-state distortion generator, lending the Surveyor its unique voice — one that retains the character of the original IVP while living in a pedalboard-friendly format. A Hi/Lo toggle expands the gain range by +14dB in the Hi position, dramatically widening the scope from subtle preamp coloring to full-on aggressive saturation. The Level control offers enough output headroom for line-level use or to drive the next pedal in your chain hard.Housed in a compact 121mm x 66mm enclosure, the Surveyor is built for real-world pedalboard use. Relay switching with true bypass ensures your unaffected tone remains pristine when the pedal is off. The power supply input is protected against reverse polarity and over-voltage up to 24V, making it a reliable and road-worthy addition to any rig at No Limit Guitar Co in Idaho Falls. Ideal For Guitarists chasing the signature clangy, aggressive attack of the classic IVP sound — especially with single-coil pickups and full-range speakersBass players seeking transformer-loaded saturation that preserves low-end weight and definitionSynthesizer and drum machine musicians looking for a unique harmonic distortion and preamp coloring tool in pedal formatStudio and recording artists who want frequency-selective gain shaping as a creative sound design toolPedalboard-focused players who demand a compact, true bypass drive pedal with professional-grade build quality Key Features Pre-Clipping Two-Band Shelving EQ By placing the Bass and Treble controls before the clipping stage, the Surveyor allows you to apply gain selectively to specific frequency bands — a design that is the complete opposite of conventional drive pedals and the key to its uniquely flexible tonal range.Transformer-Loaded "Tube Voice" Distortion The transformer-loaded distortion circuit gives the Surveyor its distinctive, harmonically rich character. It responds dynamically to the frequency content of your input signal, producing textures that range from light preamp coloring to aggressive saturation.Hi/Lo Gain Range Toggle The Hi/Lo switch adds +14dB of gain range in the Hi position, allowing the pedal to cover everything from subtle tonal enhancement to full saturation — all within a single, compact unit.True Bypass with Relay Switching Relay-based true bypass switching ensures zero signal degradation when the pedal is disengaged, keeping your clean tone completely uncolored.Versatile Signal Compatibility The Surveyor is equally effective with guitar, bass, synthesizers, drum machines, and vocals — making it one of the most broadly useful drive and preamp pedals available for creative signal chains.What's Included Electronic Audio Experiments Surveyor Instrument Voicing Preamp PedalDownloadable owner's manualManufacturer warrantyNote: No battery operation — requires 9V DC regulated, isolated power supply (100mA minimum, not included)Technical Specifications Body Compact steel enclosure Dimensions 121mm x 66mm x 40mm Weight 0.4 kg Bypass Relay switching, true bypass Input Impedance 1MΩ @ 1kHz Output Impedance <1kΩ @ 1kHz Power 9V DC, 2.1mm center negative barrel Current Draw 70mA Recommended PSU Regulated, isolated, 100mA minimum Over-voltage Protection Up to 24V Battery Not supported Controls Level, Gain, Bass, Treble, Hi/Lo toggle Bass EQ Pre-clipping low shelf ±12dB @ 100Hz Treble EQ Pre-clipping high shelf ±12dB @ 3kHz Hi/Lo Range +0dB (Lo) / +14dB (Hi) Current Version V2.5 (Spring 2024) Get Your Hands on the Surveyor Today Stop by No Limit Guitar Co in Idaho Falls to experience the Electronic Audio Experiments Surveyor for yourself — our staff are well-versed in boutique effects and happy to walk you through what makes this pedal so distinctive.
