The AMT Electronics HR-1 "Heater" is a booster/overdrive pedal built on a JFET "Screamer" circuit, meaning it follows the general approach of the Tube Screamer family of drives: a warm, mid-focused push that can tighten up an amp or add grit to a clean tone. AMT describes it as a pedal for players who want that style of overdrive from a modern build, with high-quality components and film capacitors in the sound section1. It sits in the wider family of overdrive pedals, and players comparing this circuit style may also find the Boss SD-1 vs Ibanez TS9 Tube Screamer comparison useful background.
What it does
The HR-1 takes the Screamer formula and builds it with modern parts. The design points AMT lists on its product page are component-quality measures, the kind makers typically highlight for signal clarity1:
| Design point | What AMT says |
|---|---|
| Circuit type | JFET "Screamer" booster/overdrive2 |
| Components | High-quality parts1 |
| Signal section | Film capacitors1 |
| Availability | Listed as available now1 |
Beyond the basic drive function, AMT's media page for the HR-1 notes an IR-based cabinet simulation. On this pedal, one IR (an impulse response, a digital snapshot of a speaker cabinet's sound) covers both the left and right channels of a preset, so the cab sim applies in stereo rather than per side3.
How AMT demos it
AMT has published a demo of the HR-1 Heater on its media center, which shows the pedal in use2.
The pedal itself works in any standard guitar signal chain; the demo is AMT's own presentation of the HR-1, not a requirement for how it must be used.
