User manual ROLAND FRV-1

[. . . ] However, its unique sound characteristics--including the mechanical resonance of its springs--are a perfect match for guitar. Surf music guitarists consider its sound to be indispensable, and it has achieved long-lasting popularity among blues, country, and rockabilly players as well. The 1963 Fender Reverb model is particularly revered, and was the basis for the reverb circuit built into guitar amps such as the TWIN REVERB®, which was first introduced that same year.

[. . . ] They are apparent as the DWELL knob is turned up, and also when dynamic, percussive sounds are played into the unit. These sound characteristics are particularly popular in surf guitar music, and are an integral part of the genre. As with the other characteristics of the Fender Reverb, the FRV-1 faithfully models these resonance sounds. Turning the DWELL knob to the left will reduce their level and create more of a "room" reverb sound. * 0 dBu = 0. 775 Vrms * The battery that was supplied with the unit is for temporary use, intended primarily for testing the unit's operation.
