The AMT Electronics O2 is a preamp and effects pedal from AMT Electronics, listed by the maker as the "O2 Preamp & Effects Pedal"1. It puts a preamp stage and a set of processing features in a single pedal, and AMT lists it as available now2.
What it does
The O2's processing centers on a parametric EQ that can be placed before or after the preamp stage, which AMT describes as "Parametric Pre/Post EQ"3. A parametric EQ lets a player choose not just how much of a frequency band to cut or boost, but where that band sits, which makes it useful for shaping a tone around a particular guitar or cabinet.
Among the tone controls, the HIGH knob "controls the amount of high frequency in the signal," according to AMT's product page2.
The pedal also carries two features that shape the finished sound rather than the raw tone:
- Noise Gate (global setting): a gate that applies across the unit rather than per preset, useful for taming the noise floor of a high-gain preamp1
- IR cab sim: impulse-response speaker simulation with one IR loaded for both the left and right channels of each preset1
The IR cab simulation running in stereo, with left and right channels per preset, means the O2 can feed a stereo rig or a pair of powered speakers with a cabinet response applied after the preamp1. Players comparing this kind of feature set with other units in AMT's range can look at the AMT Electronics U-2 Pangaea Brain Frame Ultima or the AMT Electronics AMT Pangaea CP-100FX, which also handle speaker simulation and effects processing.
