Peavey Audition 30 is a versatile guitar amplifier designed for both practice and performance. It features two inputs for accommodating instruments with varying output levels, a 3-band EQ for tone shaping, and a "Push Saturation" switch for adding tube-like distortion. The "Push Thick" switch provides a mid-range boost for a thicker, rock-oriented sound. Additionally, the Audition 30 has a preamp output for connecting to mixers or recorders, a headphone output for silent practice, and a line cord with proper grounding facilities for safe operation.
