Know Your Power. Down to the Milliamp.
The Truetone mA Meter plugs inline between any power supply output and any pedal to measure its exact current draw. Instantly diagnose power issues, optimize output matching, and make sure every pedal on your board gets exactly what it needs.
mA
Diagnose. Optimize. Perform.
Plug the mA Meter inline between your power supply and any pedal to see exactly how much current that pedal is drawing. Identify which pedals are hogging power, detect wiring faults, and ensure your outputs are correctly matched — before those issues become problems on stage.
The mA Meter provides inline milliamp measurement with zero modification to your existing setup. Plug it in, read the display, and know exactly what your pedal is drawing.
Compatible with all standard 2.1mm center-negative DC connections. Works with any 1 SPOT Pro model and the original 1 SPOT.
