Blended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement.

Citation/mention fame — how often this gear is cited across artist rigs and gear discussion.The Diezel Paul is a 45-watt all-tube 2.5-channel amplifier head from Diezel Amplification, Germany. Three MIDI-switchable preamp voices — Clean, Crunch, and Insane — span crystal-clean headroom through heavy saturated lead. EL34 power tubes and a pair of parallel and series MIDI-controllable FX loops serve professional live and studio applications. The Paul has a more vintage character than other Diezel heads and is praised for its warmth and sparkle on the clean channel alongside its Crunch voice range from Texas blues to heavy rock.
The Friedman Dirty Shirley is a 40-watt boutique tube head built around a modified Marshall JTM45 concept, voiced for vintage British classic rock crunch. It is big, beefy, chimey and articulate at once, with a remarkably touch-sensitive response that cleans up when you roll back the guitar volume and pushes into smooth, sustaining crunch when you dig in or turn up. Tweaked coupling and cathode caps give it a fat yet tight feel. It covers vintage Marshall plexi and hot-rodded gain tones and lower-gain territory, but is not built for pristine blackface cleans. Joe Perry runs multiple Dirty Shirley heads in his Aerosmith touring rig. Ideal for classic rock, hard rock and blues-rock.
