Founded in 2015 and hailing from Boston, Massachusetts, Electronic Audio Experiments are more than just a pedal manufacturer, they are "an exploration in sound and texture via electronics". The Electronic Audio Experiments Surveyor is a compact re-interpretation of the Instrument Voicing Preamp (aka IVP), a cult classic and long discontinued rackmount preamp.

Featuring a unique, transformer based “Tube Voice” distortion generator, the Surveyor is highly responsive to the frequency content of the input signal. A two-band Baxandall EQ is placed before the distortion which is actually the complete opposite to how most drive pedals work. It may seem unorthodox, but by using this method, the gain can be selectively applied to a specific frequency band. This is incredibly useful is you want to boost the treble for that signature clangy sound or boost the bass for a fuzz overload!

Controls 

  • Level – Overall volume, with more than enough range for line level output or to overdrive a tube amplifier
  • Gain – Amount of overdrive/saturation equally applied to all frequencies; highly interactive with the Bass and Treble settings
  • Bass – Pre-gain low shelf boost/cut, +/-12dB @ 100Hz
  • Treble – Pre-gain high shelf boost/cut, +/-12dB @ 3KHz
  • Hi/Lo (switch) – Sets the range of the gain control. In the Lo setting the gain range is -15dB to +12dB, in the Hi setting the gain range is +9dB to +36dB. 

Specifications: 

  • Bypass: Relay switching with true bypass
  • Input impedance @ 1 Khz: 500kΩ
  • Output impedance @ 1 Khz: 2kΩ
  • Power: 9V DC, 2.1 mm center negative barrel. The current draw is 75 mA.
  • We recommend a regulated, isolated power supply rated for 100 mA minimum. The PSU input is protected against reverse polarity and over-voltage up to 24V. Our pedals do not accept batteries.

Preamp & DI Pedals

A preamp brings an instrument signal to a controlled level and shapes its impedance, gain and frequency balance before amplification or recording. A DI converts the signal for a balanced, low-impedance connection and may include ground lift, pad and transformer isolation. Combined units can add drive, cabinet filtering, effects loops and parallel outputs while keeping the direct path stable.

Bass

Voiced or equipped to retain low-frequency fundamentals and the higher headroom of a bass signal. Clean blends, crossovers and bass-specific filter ranges can preserve weight and articulation while the effected portion adds harmonics, movement or ambience.

Vocal

Designed for microphone-level signals and the frequency, dynamics and feedback behaviour of the human voice. Input gain, balanced connections, phantom power and pitch tracking may be provided so effects respond correctly before the signal reaches a mixer or PA.
