Topics include: Gain-based effects, like distortion, compression, volume pedals, and gates Tone-based effects, including graphic and parametric EQ, and the wah-wah pedal Modulation effects, like the flanger, phase shifter, and tremolo Ambience effects, including reverb and delay The journey to incredible guitar music never ends. No matter how experienced you are with a guitar, there is always room for improvement to your tone and sound. Whether you're looking for the sound of angels or thunder, Guitar Amps & Effects For Dummies will help you achieve the music you hear in your dreams.
