Hiwatt Custom DR20/0.5 Head

The legendary Hiwatt preamp circuit and tonestack found in the DR103/504 feeding a 20W (switchable to 0.5W) output section offers classic Hiwatt Headroom, clarity, instantaneous response, sonic depth, and detail, with breakup at recording and club volumes (switch to 0.5W in the greenroom).

Iconic 60s British tone in a lightweight and portable package.

FEATURE OVERVIEW

• — Original linked input circuit as famously modded for Pink Floyd, increasing signal to the V1 preamp valve and producing a fuller, more present and forward sound.
• — Optional "Fat Switch" mod for a fuller tone with extended low-end range and increased volume.
• — Normal and Brilliant channels. Versatile and intuitive, perfect for bringing life out of dark pickups or taming shrill high end in bright pickups.
• — Volume for any gig — Switchable wattage allows switching from 20W down to 0.5W for bedroom playing and smaller venues.
