Critic Reviews

Keith McMillen Batt-O-Meter

bassmusicianmagazine.com

The Keith McMillen Batt-O-Meter stands out as a must-have tool for musicians, allowing battery testing without removing them from instruments, bringing peace of mind during performances. Its sturdy build, clear readout, and innovative features like voltage and remaining life percentages make it a practical addition to any gig bag. However, a notable limitation is its inability to measure 18-volt systems, which could affect some users. Despite this, its ease of use and effectiveness for standard 9-volt batteries, combined with an affordable price, make it a smart buy for any musician looking to avoid mid-performance battery failures.

Keith McMillen Instruments: Batt-O-Meter battery tester | Tape Op Magazine | Longform candid interviews with music producers and audio engineers covering mixing, mastering, recording and music production.

The Batt-O-Meter is a clever and practical solution for musicians tired of guessing battery life in their gear. Its ability to test various 1.5V batteries, especially 9V types common in effects pedals, is a game-changer, eliminating the hassle of opening up devices. The custom power probe offers accurate readings, including remaining hours of use, a feature that can save time and frustration. However, it’s worth noting that the Batt-O-Meter does require a 9V battery itself to operate, which could be a minor inconvenience. Still, for performers and studio owners with extensive pedal collections, this tool is an invaluable time-saver at a reasonable price.
