1960's Hybrid (Tube-Transistor) Standel Imperial Model 5100, serial: 4427-1

Rare Vintage 1960s Standel Imperial Model 5100 Hybrid Guitar Amplifier Head – Serial #4427-1

Up for sale is a rare, mid-century piece of Southern California tone history: a vintage Standel Imperial Model 5100 hybrid amplifier head (Serial Number: 4427-1).

In the mid-to-late 1960s, Bob Crooks and the team at Standel briefly pioneered incredible hybrid designs that bridged the gap between eras—combining a highly articulate, pristine solid-state preamp section with a robust, warm tube-driven power section. This gives you the legendary, massive clean headroom Standel is famous for, paired with the organic compression and warmth that only vintage glass and heavy-duty transformers can deliver.

Because it's a standalone "piggyback" head rather than a massive combo cabinet, it is highly portable, much easier to ship, and ready to be paired with your favorite vintage or modern speaker enclosure.

Features & Tonal Character:

• True Hybrid Design: Crisp, ultra-clean solid-state front end paired with a warm, powerful tube power section.
• Massive Clean Headroom: Exceptional clarity and robust note definition—the ultimate pedal platform for jazz, country, steel guitar, or psychedelic rock.
• Classic 1960s Aesthetic: Features the striking front control panel and iconic black Tolex styling.
• Famous for delivering pristine clarity and robust note definition, vintage Standel amps from this era were the secret weapon for jazz greats like Wes Montgomery and psychedelic rock pioneers like Jorma Kaukonen of Jefferson Airplane.

Tolex cover shows wear and tear comenserate with age, the Intensity/Speed pot doesn't work for the vibrato, otherwise the amp performs great!
