Big power with practical control
The Fillmore 100 gives you full 100-watt performance when you need maximum headroom and low-end authority. For smaller venues or controlled recording sessions, the global power switch drops the output to half or low power without changing the core feel of the amp. Each mode uses a different tube configuration, so you still get natural valve response at any level. This means you can match your volume to the room while keeping your tone consistent and predictable.
Consistent tones across both channels
Both channels are fully independent but identically laid out, each with Clean, Drive, and HI modes. This makes it simple to set up matching sounds or move between gain stages without surprises. Every channel has its own gain, EQ, presence, reverb, and master controls, so you’re not compromising when switching. It’s a straightforward layout that rewards careful dialling and keeps things familiar during rehearsals and gigs.
Vintage voicing with modern reliability
Built around Mesa’s long-standing tube expertise, the Fillmore 100 blends tweed-inspired character with refined power handling. The Class A/B Dyna-Watt power section delivers fast attack and solid tracking in the low frequencies, even when playing dynamically. Silicon diode rectification keeps the response tight and reliable, making the amp feel stable under load while still retaining the warmth expected from an all-tube design.
Stage-ready combo design
This 1x12 combo pairs the Fillmore circuit with a Celestion Custom 90 speaker for balanced projection and clear articulation. The open-back cabinet helps the sound spread naturally on stage, while the marine-grade Baltic birch construction keeps the build solid without unnecessary bulk. At 57 lbs, it’s manageable for transport and comes supplied with a footswitch and fitted slip cover, so you’re ready to play straight out of the box.
