Key Features
The Mesa Boogie Fillmore 100 Head is designed for guitarists who want classic tones with modern flexibility on stage and in the studio. At its core is a powerful all-tube design using four 6L6 valves, delivering the feel and authority of a 100-watt amp while remaining practical to use. A global power switch lets you choose between full, half, or low power, so you can dial in the right balance of headroom, response, and volume for your space. This makes it just as workable in smaller venues as it is on larger stages.
Both channels are identical and fully footswitchable, each offering clean, drive, and hi modes with independent EQ, gain, and master controls. Add the built-in long-tank spring reverb and a buffered effects loop, and you’ve got a head that keeps things simple while covering a wide range of usable tones.

The Fillmore 100 Head gives you the authority of a high-powered valve amp without locking you into one volume level. Its global power switch lets you move between full, half, and low power settings, changing both output and feel. Full power delivers maximum headroom and punch, while half power tightens things up for smaller stages. Low power runs the output section differently for a softer response that works well at reduced volumes. You can match the amp to the room without sacrificing the core tone or dynamics.
Both channels on the Fillmore 100 are identical, which keeps switching simple and predictable. Each channel offers clean, drive, and hi modes, letting you set up matching or contrasting sounds without rethinking your controls. Independent EQ, presence, gain, reverb, and master controls mean each channel can be dialled in precisely. This layout suits players who rely on footswitching mid-song and want reliable results every time they change channel.
This head is built around a traditional all-tube signal path, using 12AX7 preamp valves and 6L6 power valves for a familiar response under the fingers. The Dyna-Watt Class A/B power section focuses on clarity, low-end control, and dynamic tracking, so your playing nuances come through clearly. Convection cooling and a fixed-bias design help keep maintenance straightforward, which is reassuring if you’re gigging regularly or relying on it in the studio.
The Fillmore 100 Head keeps extras useful rather than excessive. A long-tank spring reverb adds depth without masking your core tone, and it’s adjustable per channel. The fully buffered series effects loop works well with pedals and rack units, maintaining signal integrity. Speaker outputs for 4- and 8-ohm cabinets make pairing easy, and the included footswitch covers channel changes straight out of the box. It’s a focused design that fits neatly into professional rigs.
