The AMT Electronics Preamp F1 is a guitar preamp pedal designed to replace an amplifier's front end in a pedalboard rig. AMT describes it as an analog preamp with three gain modes, Clean, Low gain and High gain, paired with a power amp section offering nine selectable types, a global noise gate, and an IR cab simulator for feeding a mixer, interface or power amp directly1.
Because the preamp and power amp stages are analog while the cabinet simulation is IR based, the F1 covers the full amp signal chain in one box: you get your gain structure, the feel of a power section, and a recorded-style cab tone without an amplifier21.
What the F1 does
The F1's analog preamp section gives three gain modes, and the power amp section behind it adds nine selectable types1. On a real amplifier the power stage contributes its own character as it works harder, and modeling that stage separately from the preamp is what separates a preamp pedal like this from a simple overdrive or distortion pedal.
| Section | Modes or types | What it gives a player |
|---|---|---|
| Preamp | Clean, Low gain, High gain1 | Anything from a clean platform to a full high-gain lead voice, chosen by mode rather than one gain knob |
| Power amp | 9 selectable types1 | The character of a power section working harder, separate from the preamp |
| Noise gate | Global setting1 | Tames hiss and hum, most useful in High gain mode |
A noise gate is included as a global setting1, which matters most in the High gain mode, where background hiss and hum are usually at their worst.
Cab simulator and connections
The F1 includes an IR cab simulator, with one IR shared by both the left and right channels per preset1. For connection to a mixer, the preamp has a speaker simulator mode, selected by a switch on the left panel3. That makes it usable as a direct recording or live-to-PA solution without a cabinet.
- IR cab simulator with one IR for both L/R channels per preset1
- Speaker simulator mode for connecting straight to a mixer, selected by a switch on the left panel3
- Usable direct into a mixer, interface or power amp3
Power
The F1 runs on 12V DC, center negative, drawing 6mA2, and AMT ships it with a 12V power supply included3.
The F1 needs 12V DC, center negative2, and a 12V power supply is included with it3. Power supplies and daisy chains built for lower-voltage pedals will not run it, so plan a dedicated 12V output when fitting it to a board.

Questions
What power supply does the AMT Electronics F1 preamp need?
The F1 runs on a 12V DC center negative supply, and AMT ships it with a 12V power supply included. That voltage is higher than the 9V standard most pedals use, so it cannot share a typical 9V daisy chain.
Is the AMT F1 preamp analog or digital?
The preamp circuit is analog. AMT describes it as an analog preamp with Clean, Low gain and High gain modes, plus an analog-style power amp section offering nine types. The cab simulation, however, is IR based, with one impulse response shared by both left and right channels per preset.
Does the AMT F1 have a built-in cab simulator?
Yes. The F1 includes an IR cab simulator with one IR for both left and right channels per preset, and it has a speaker simulator mode for connecting straight to a mixer, selected by a switch on the left panel.
What gain modes does the AMT F1 have?
The analog preamp section offers three modes: Clean, Low gain and High gain. A global noise gate is also on board, and the power amp section adds nine selectable types.
