The sound of a steel-string acoustic or classical guitar, played on the couch, strummed around a campfire, or performed in a concert hall, is perhaps unparalleled in beauty and harmonic richness, as most readers of this magazine can attest. Efforts to amplify acoustic and classical guitar for performance often focus on projecting a natural, uncolored sound. Nevertheless, creative breakthroughs and new approaches to your acoustic guitar playing can be found through experimentation with effects pedals, or stompboxes, that are often associated with electric guitar and bass.
