The Mesa Boogie Rectoverb 25 Head's status as a metal maven is unquestioned thanks to its dual-channel design, Dyna-Watt powered 10W or 25W operation, and Multi-Watt channel assignable power amp. Capable of operating in either Class A/B Triode or Class A/B Pentode, the flavor of the amp is nearly infinitely customizable with an additional four style modes on each channel and individual three-band EQs for carving out truly unique tone. Throw in an authentic onboard spring reverb and buffered effects loop, and you have a workhorse that can go the sonic distance.
