Legendary Hi-Headroom, crystal-clean tonal character, instantaneous response, sonic depth and detail have made this original Dave Reeve's circuit a recording and performance giant for more than 60 years. With half the power tubes of it's big brother (the DR103), the DR504 offers the iconic Hiwatt tone while allowing to play on the edge of breakup at recording volume.

The classic British sound trusted by musicians and engineers for generations.
