Lovies Guitars is excited to offer this 2026 Dr. Z PHD 10-Watt Amp Head in Black Tolex. The PHD is Dr. Z’s refined take on the legendary single-ended Class A amp concept—capturing the raw, harmonically rich grind of vintage low-wattage tweed amps while dramatically expanding headroom, clarity, and sonic authority. Inspired by the expressive touch sensitivity heard on classic recordings like Joe Walsh and the James Gang’s “Funk 49,” the PHD blends vintage feel with modern versatility in a compact, lightweight format.

At the heart of the design is a cathode-biased KT66 power tube paired with an octal-based 6SN7 preamp tube, delivering exceptional depth, articulation, and broad frequency response. The upgraded 5U4GB rectifier pushes the amp to a highly usable 10 watts, striking an ideal balance between pedal-friendly clean headroom and saturated Class A overdrive character.

Whether paired with a compact cab or a full 4x12 setup, the PHD delivers a surprisingly massive sonic footprint with dynamic response and swirling harmonics that make every note feel alive under the fingers.

WORKING CONDITION: Excellent - Works great. Everything is fully functional and performs exactly as it should.

PHYSICAL CONDITION: Excellent - Little to no signs of wear are present. The amp head is very clean overall and has clearly been well cared for.
