The Epiphone E-Series amplifiers offer great tone, great performance and unique style in a solid-state amp. Each model is cleverly designed and appointed with enough technology to enhance great tone. The 2-channel Firefly 30 DSP features Epiphone's proprietary E-valve tone circuitry, which coaxes actual tube tone from a solid-state amp. It pushes 30 watts through a special-design 10" speaker for plenty of bluesy tone while also offering 16 DSP effects plus a separate DSP reverb section, so you can call up the effect you want without having to lug around extra boxes. It provides an effects loop with an independent level control, plus an auxiliary in/out, also with level control.
