Guitar Feedback “Modeling” with Samplers in Recording Posted August 20, 2019 Really interesting article. I've always loved the sound of controlled feedback since the late 60's. I use it a lot in my own music and generate it with either my Sustainiac-equipped guitar, an Ebow, and/or the Feedbacker effect in my Roland VG-99. But â€œmodelingâ€ it with samplers as you described sounds intriguing. I'll be sure check that out for another tool in my sound effects box. Thanks Craig.
