The result of more than 10 years of tweaking and development, Revv Amplification’s Dynamis D40 merges the greatest American and British tube amp tones of the past with a vast array of cutting-edge functionality features. This 40-watt tube amplifier head comes equipped with two channels — Clean and Overdrive — designed to capture everything from full-bodied sparkling cleans to ripping leads drenched with preamp saturation. Each channel sports its own dedicated set of EQ/Gain/Master Volume controls, with global Presence and Depth knobs for further fine-tuning. It’s a fine foundation for old-school tube tones, but only the beginning of the Dynamis D40’s superior design — a Two Notes Torpedo-embedded reactive load, DynIrs, buffered serial FX loop, 40/10-watt power scaling, and extensive USB/Bluetooth/MIDI functions elevate this amp’s stage and studio utility far beyond any retro-style tube amp. All in all, the Revv Amplification Dynamis D40 is a true revelation in the world of guitar amplification and a must-have for the musician who reveres the authentic tube tones of the past but demands all the best of modern amplifier design
