The Framus Cobra 100W is a legendary, German-engineered all-tube guitar amplifier head revered as a holy grail of early 2000s metalcore and extreme metal. Known for its devastatingly aggressive, lightning-fast tracking, and tight low-end, this three-channel monster was a staple for bands like Killswitch Engage, As I Lay Dying, and Chimaira


Key Specifications & Architecture

  • Power Output: 100 Watts via an all-tube chassis.
  • Tube Complement: Four EL34 (or E34L) power tubes and five ECC83 (12AX7) preamp tubes, giving it a distinct punchy midrange and massive power section headroom.
  • Channel Layout: Three completely independent channels (Clean, Crunch, and Lead). Each channel has dedicated controls for Gain, Bass, Mid, Treble, Presence, and Volume.
  • Global Controls: Dual switchable master volumes (ideal for a solo boost) and a global Deep/Resonance control to anchor the low-end punch.
  • Tone Shaping Switches: The Clean channel features a Bright switch, while the Crunch and Lead channels feature a Notch switch to scoop out specific midrange frequencies for a modern metal tone.
  • Rear Panel: Fully equipped with an integrated MIDI interface for seamless channel switching, a balanced/TRS effects loop mix, external individual tube bias test points, and selectable 4, 8, or 16-ohm speaker outputs

Tonal Character

  • Clean Channel: Surprisingly pristine with immense headroom, drawing comparisons to a Roland Jazz Chorus. It stays clean even at high volumes but can push into smooth breakup if pushed.
  • Crunch Channel: Highly versatile, moving from classic British-style classic rock grind to tight, aggressive, percussive thrash rhythms.
  • Lead Channel: Pure brutality. It features an insanely fast attack and raw high-gain saturation that requires no overdrive boost pedals to stay tight.


The amp spent almost its whole life in the box. It was shipped to the states in 2013 and has been in the box until we opened it here at Tone Central Station. We fired it up and tested it out quite thoroughly. It is FULLY FUNCTIONAL and sounds INCREDIBLE!!!! It comes with the original box, manual and power cable. No footswitch. The front panel is bubbling from the age and outside elements. Come aging is shown in the tolex.
