Web13 de abr. de 2024 · This compact preamp is based on the lauded Fishman Platinum design, and offers a high-impedance preamp to “optimally condition” your acoustic pickup signal, plus four bands of control to adjust bass, mid, treble, and brilliance – especially handy if you don’t have EQ sliders on your acoustic.
WebAnswer (1 of 2): Acoustic impedance is quite a simple concept. Sound is small pressure waves - repeated compressions and rarefactions of air. In free space these waves gradually shrink in pressure, mainly through friction, and get smaller - the sound gets quieter. If you put something in the pat... WebHá 1 dia · Core Features.
