It's a big clean machine. The DR40M is a 40W dual-EL34-based head, delivering great clean and distortion tones. The three 12AX7 preamp tubes stay very clean while the power tubes provide the breakup. The DR series turns on a dime, cleaning up with a quick turn of the guitar volume knob. It’s ideal for pedal-lovers, offering loads of clean headroom. The circuit is designed to maximize the power from the EL34 tubes to deliver great crunch.
