The PRS HDRX 20 Head offers a powerful blend of vintage-inspired tone and modern usability. This 20-watt amp is built around a newly-documented "Authentic Hendrix" Touring Circuit, modeled after one of Jimi Hendrix's personal amps studied by PRS. It delivers the rich, articulate sound of late-'60s British amplifiers, designed to shine without becoming overly harsh. Key features include a 3-band tone stack, a 2-way bright switch, a high-mid gain switch, and internally bridged channels, allowing for precise tonal control without the need for external jumpers. The addition of a Master Volume control makes the HDRX 20 user-friendly for both stage and home settings, allowing you to manage output without a volume attenuator. The amp uses two 5881 power tubes and three 12AX7 preamp tubes, providing a warm, organic voice that handles both clean and overdriven tones beautifully.
