The Electronic Audio Experiments Surveyor is a compact re-interpretation of the Instrument Voicing Preamp (aka IVP), a cult classic and long discontinued rackmount preamplifier. The IVP is best known for its distinctively clangy tone and harsh attack at high treble settings—especially in conjunction with an aluminum neck guitar, single coil pickups, and full range speakers.
The Surveyor features a unique, transformer-based “Tube Voice” distortion generator that is highly responsive to the frequency content of the input signal. This is achieved by placing a two-band Baxandall EQ before distortion is applied—the complete opposite of most drive pedals. Using this method, gain may be selectively applied to a specific frequency band: boost the treble for that signature clang, or maximize the bass for fuzz overload. This variety of saturated textures transcends genre labels.
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.
