The AMT Electronics AMT Ozzulator Chorus, sold as the AMT Chorus CH-2, is a chorus pedal designed to work in the signal chain of a guitar or bass. AMT describes chorus as a modulation effect that simulates the choral, polyphonic sound of musical instruments, and the pedal carries far more than a chorus alone: an analog preamp, a power amp section, an IR cab simulator, a compressor, a noise gate, and a delay or reverb option, all built around the chorus itself12.
How the chorus works
AMT explains the effect as adding delayed copies of the original signal to itself, delayed by values on the order of 10 to 20 milliseconds, with that time shift continuously changing. The direct signal stays 100% analog and is mixed with the effect signal2. The pedal offers a choice of two chorus types, Chorus S or Chorus x3, and AMT describes the CH-2 as having a wide set of effect sound controls2. For more on how pedals of this kind behave, see the Chorus Pedals page.
Presets, stereo and the added effects
The Ozzulator's feature set goes well beyond a standalone chorus. Per preset, the pedal offers1:
- Analog Preamp with Clean, Low gain and High gain options1
- Power Amp with 9 types1
- IR cabsim, with 1 IR for both L/R channels per preset1
- Compressor1
- Delay or Reverb effect, selectable per preset1
- Noise Gate, a global setting1
The stereo arrangement runs through the cab simulation: each preset carries one impulse response that covers both the left and right channels1. The delay and reverb options are a per-preset choice, so a preset carries one or the other rather than both at once1. Players who want the added effects in a dedicated form can look at Delay Pedals or Reverb Pedals, and the built-in gate and compressor relate to the separate Noise Gate Pedals and Compressor Pedals categories.
Where it sits on a board
Because the preamp offers Clean, Low gain and High gain options and the power amp section offers nine types, the Ozzulator can act as more than a modulation pedal at the end of a chain: it carries gain-staging and speaker simulation stages that players often get from separate Preamp Pedals or Speaker Simulation Pedals. AMT lists the CH-2 as available now2.

Questions
Is the AMT Ozzulator Chorus stereo?
Yes. The pedal works with left and right channels: each preset carries one IR (impulse response) that is applied to both the L and R channels, so the chorus and cab simulation run in stereo. The chorus effect itself works by mixing the direct signal with delayed copies of it, and AMT states the direct signal path is 100% analog.
Does the AMT Ozzulator Chorus have a cab simulator?
Yes. The Ozzulator Chorus includes an IR-based cab simulator, with one impulse response covering both the left and right channels of each preset. That sits alongside the pedal's analog preamp and its power amp section, which offers nine types.
Can the AMT Ozzulator Chorus add delay or reverb?
Yes, but one at a time. Each preset can select either a Delay or a Reverb effect as an added layer on top of the chorus, the preamp, the power amp types, the IR cab simulator, the compressor and the noise gate. It is a choice per preset rather than both effects running together.
Does the AMT Ozzulator Chorus have a noise gate?
Yes. The pedal includes a Noise Gate, and AMT lists it as a global setting, meaning it applies across the pedal rather than being set individually for each preset. It sits alongside the built-in compressor in the pedal's signal chain.
What preamp options does the AMT Ozzulator Chorus have?
The analog preamp offers three options: Clean, Low gain and High gain. That gives the pedal a gain-staging stage before the chorus, and it is followed by a Power Amp section with nine types and an IR cab simulator covering both channels of each preset.
