Bogner Helios 50 ~ Half Stack – Handwired 50 Watt Head, Matching 412ST Cab and Footswitch

The Head…
Designed to sound just like a classic Plexi amplifier, the Bogner Helios 50 tube amplifier gives you high-octane tone. It’s an aggressive 2-channel amp, and guitarists love the versatility of the separate Plexi and hot inputs. The Plexi input gives you Plexi-style gain on channel two and an ultra-clean gain stage on channel one. The hot input gives you a hot-rodded high gain structure on channel two with a clean to Plexi gain range on channel one. Whichever input you plug your guitar into, the Bogner Helios 50 rocks!

The Cab…
Bogner claims that their 412ST Helios cabinet gives you chunky bass response that’s rich, fat, and woody, and guitarists are inclined to agree. The sound is resonant without becoming boom-y, your mids and highs cut through without sounding harsh, and you can really feel these four 12″ speakers respond to the nuances of your playing. Bogner cabinets are built to last, so you can expect the 412ST Helios to handle whatever abuse your gigs can dish out. Whether you play a Bogner guitar amplifier or anything else, you can expect lively, vibrant sound from the Bogner 412ST Helios speaker cabinet.

Our Helios half stack comes to us in excellent if not mint condition. The rig was never gigged! There is one small ding in the tolex at the bottom front lower edge of the cab. The amps bias has been checked and is currently running at 30.49 DCV (cool) – These are set up this way at Bogner factory to ensure maximum tube life. The rig sounds incredible!
