DR504 - Hiwatt Custom 50 Head

The little brother to the DR103 - the DR504 is a design classic! It has the same controls and features as the DR103, except it uses 2 x EL34 in the power stage, providing a more than generous 50 watts RMS. It is lovingly hand built to the highest possible standards.

— Normal and Bright channels with independent High and Low impedance inputs for each channel. Versatile and intuitive, perfect for bringing life out of dark pickups or taming shrill high end in bright pickups.

— Link the two channels for extra punch and dynamic control of your EQ via the independent channel volumes. Unleash the ’jumped’ channel sound Hiwatt is famous for.

— All the clean headroom you could want.

Every DR504 is proudly handcrafted and built to order for you in our Custom Shops. Please allow up to 4 week lead time while your amplifier is being meticulously hand-wired.
