Get ready to transform your guitar performance with the Weber Speakers Mass 200, a powerhouse in the world of guitar power attenuators. Designed with meticulous attention to detail, this attenuator lets you enjoy the full tonal richness of your amplifier at much lower volumes. Whether you're practicing at home or performing on stage, the Mass 200 ensures that every note is delivered with clarity and precision.

The Mass 200 is compatible with tube amplifiers up to 200 watts, making it versatile enough for both practice amps and larger stage units.

The intuitive controls allow for easy adjustment of volume levels, and the built-in bypass switch gives you the flexibility to switch between attenuated and full-power modes seamlessly. With its durable construction and high-quality components, the Mass 200 is built to withstand the rigors of frequent use while delivering consistent performance.

Works best for my amp

Since my BV150H is a 150 watt tube amp it's absolutely unusable in my home and small venues. For such locations this attenuator is indeed a life saver. Due to the ridiculously high wattage of my amp I use two such attenuators with two parallel outputs of my amp. Then I set my cab to operate in stereo mode and then I connect the outputs from the two attenuators into the stereo inputs of my cab.

It adds minimal coloration to my amps tone. Compared to many other reactive attenuators it costs pretty low too. Of course it doesn't have stuffs like IR loader and other bells and whistles but then again I never felt the need of such stuffs. I prefer to record my amps in the old fashioned way, with microphones.
