Because of the naturally quiet volume of these guitars, which are typically small parlor guitars, a high output pickup is typically installed for amplification. Part of the magic of a rubber bridge guitar comes from the duality between the pristine, crisp acoustic sound of the instrument and the rich, powerful signal of the pickup.
The Evolution Rubber Bridge was recorded using a nearly century-old parlor guitar converted to a rubber bridge guitar and equipped with a classic Tokyo-style gold foil pickup. The pickup and stereo microphone signals were recorded separately so you could mix the warm, punchy sound of the pickup and the crisp, clean mic signal. The Evolution Rubber Bridge was recorded with the guitar tuned a whole tone lower than standard tuning, giving it a deeper tone and a naturally lower playing range.
We developed the library in collaboration with Rosewood Recording Company, one of Utah’s most venerable recording studios. Guy Randle, owner and engineer of Rosewood Recording Company, has incorporated analog audio equipment to skillfully shape and highlight the rich tonal qualities of the guitar. The Evolution Rubber Bridge includes both the recorded signal and the enhanced signal.
The Evolution Rubber Bridge is based on our Evolution engine, which provides you with a variety of features: an innovative pattern editor, automatic chord detection, and an extensive collection of built-in effects to add the final polish to your guitar tone. If you have used any of our guitar or bass libraries that use the Evolution engine, its interface and workflow will be very familiar to you.
The library includes a variety of ready-to-use factory presets for a variety of guitar tones. Some presets focus on the acoustic side of the guitar with pristine, clean tones, while other presets take advantage of the guitar’s electric component by running its pickup signal through a guitar cabinet, sometimes with the addition of spring reverb or even distortion.
