Marshall Powerbrake PB100 Power Attenuator

Get that famous Marshall overdriven amp sound at reasonable listening/recording levels! Buy It!

The pure, unadulterated tonal majesty of a fully cranked all-valve Marshall is something that every guitarist should experience on a daily basis.

Unfortunately, the awesome levels of volume this produces makes it totally impractical for most everyday situations. What you really need is a device that will absorb some of the amp's energy without affecting its natural qualities of distortion, tone and feel.

The Powerbrake is that dream device, providing full control of the level between your amplifier and speaker without squashing any of the dynamic feel and tone. This totally roadworthy box links between your amplifier and either one or two cabinets.

A rotary dial on the front panel gives you eleven (11) level selections in 3dB increments, This allows you to go from unchained, full stage volume, right down to bedroom or apartment level in an instant -- even with the amp's Master Volume on maximum.

Boss RC-2 Loop Station pedal -- make your sound even bigger!

No external power supply is required, since the Powerbrake's reflected inductive load circuitry eagerly soaks up the amplifier's power. It then dissipates the resulting heat via a reactive fan which automatically responds to temperature increases created when you use greater attenuation levels.

With the Marshall Powerbrake you can drive your amp to the limit without losing control -- or your hearing!
