Created in 2008, the ZAM from Zampower transformed the power supply of active instruments thanks to stable voltage and consistent sound. Adopted by many musicians since its launch, it guarantees reliability, performance, and peace of mind on stage as well as in the studio. A durable and essential tool to avoid battery failures and improve the sound quality of any active instrument.
Among the discreet but essential innovations that truly improve musicians’ lives, the ZAM from Zampower holds a special place. Designed to permanently replace batteries in active instruments, this small unit has become over time an indispensable companion for many bassists and guitarists. It provides a stable, clean, and continuous external power supply, specifically designed for electronics operating at 6, 9 or 18 volts. The principle is simple. The ZAM connects to the instrument via a stereo jack cable, delivers perfectly regulated current directly to the preamp, and completely eliminates dependence on batteries. The instrument then receives constant voltage that guarantees maximum performance in all circumstances.
The ZAM was conceived and developed by three passionate musicians and technicians. Dominique Bertram, Franck Bedez, and Philippe Sutter combined their skills to create a reliable, secure device suited to the demands of both stage and studio. Their idea quickly established itself as a true innovation, to the point of being recognized at the Concours Lépine. The success of the project owes much to their deep knowledge of equipment, musicians’ constraints, and the weaknesses of the traditional battery-based system. They wanted to offer a technical solution that was simple, effective, and immediately usable. Their approach resulted in a concept innovative enough to be protected by a patent.
The strength of the ZAM lies in its reliability. When using an active instrument, the slightest voltage variation can alter dynamics, tonal balance, or even cause abrupt cutouts when a battery weakens. The ZAM eliminates these uncertainties by maintaining a perfectly constant power supply. The result is immediately noticeable. The sound gains presence, precision, and openness. The low end becomes more stable, the highs clearer, and the instrument’s overall response remains consistent, whatever the context. The unit also offers a very useful Mute function for silent tuning or managing a quick change. It integrates naturally into a setup without disrupting playing habits.
Since its launch, I have been using the ZAM on a daily basis. I adopted it from its very first appearance, and it has been an integral part of my gear from day one. For me, going back to batteries is impossible. The peace of mind it provides alone justifies its adoption, but above all it is the consistency of the sound that convinces me night after night. When I plug in my instrument, I know exactly what to expect. No more loss of dynamics, no more surprises, no more battery dying at the wrong moment. The ZAM has become an essential element of my setup and I never play without it. It simply never leaves my equipment.
The ZAM is aimed at those who seek comfort, reliability, and sound quality at the same time. Its installation sometimes requires checking or a slight adaptation of the jack socket, but once in place, it becomes a real asset. It also significantly reduces battery usage, which represents an economic and ecological gesture. For active musicians, stage technicians, and lovers of clean and consistent sound, it is a solution of choice. And for me, it has become an indispensable partner, an accessory without which I can no longer imagine playing.
