Product Description

zZounds is an
authorized Marshall dealer

You want great, overdriven tone. Your valve amp sounds its best CRANKED. But you're tired of your dental fillings shaking loose. Or maybe you're in the studio and you don't want your amp bleeding into everyone else's mics. Or maybe you're one guitar practice away from getting evicted! How can you get monster sound at quieter volume levels? Simple: Put a brake on it.

The Marshall Power Brake is the power attenuator that delivers great sound at low volume levels. There are other attenuators or load boxes available, but they don't provide the right type of inductive load. Your amp needs to think it's connected to a speaker. That's what the Power Brake does. The other guys? At best, they cause your amp to sound thin and feeble. At worst, they can blow your valve's output transformer -- Ouch! Get the Marshall Power Brake. It's safer for your amp and safer for your ears zZounds is an authorized dealer of Marshall products.

"MY UPCOMING BAND RISE AND FALL IS COMING TO THE SUNSET STRIP"

Sound: I never had one of these before so i baught it thinking okay i need the volume to be low and the tone to be great and it did just that. If you want the real tone of your amp then you need to buy this not one of those THD junk YOU NEED TRUE MARSHALL TONE!!!! Feature: Not many features to talk about Ease of Use: Theres only one knob how hard is that..... Quality: The quality is great I guess can't go wrong with a marshall Value: Yeah I thought the price needs to come way the hell down I mean seriously its a VOLUME CONTROL not an amplifier Manufacturer Support: I have dealt with Marshall products my whole life my only other suggestion if you wanna jam with one of the best amps out there u need either a Marshall or a Hughes & Kettner or if your rich and can afford a dumble but I wont even get into that The Wow Factor: ITS PRETTY SEXY Overall: I BETTER BE SATISFIED WITH THIS PRODUCT FOREVER FOR THIS KINDA MONEY

"Clean Thick Thumpin Tone No Signal Loss"

Sound: Makes so change in tone. Keeps the highs, mids, and lows where they need to be for practicing at home, recording or playing small clubs. one knob to turn. to cables to plug in very simple. Feature: Only one knob how simple. Ease of Use: Once again one know. stick it on top of your amp away from the vent and your good to go. Quality: Built like a tank. Heavy like one too. Value: THD hot plate is nice, too many options. have to choose 4 or 8 or 16 ohm.. this attenuator is the standard easy to use tone maker. Manufacturer Support: Haven't needed any. Like any marshall though i have never had a problem The Wow Factor: who cares whatit looks like, its what it sounds like, who's gonna see your powerbrake in the studio on your record? Overall: I will always use this product. The guy that said it blew his tubes is a MORON. the powerbrake didnt blow his tubes, HE blew his tubes. That guy probably bought it and said "oh cool, i can turn everything up to 10 now" and kazaam 1972 marshall head broken by an idiot. Give that Head to charity you dont deserve it. Oh and you amp Tech should stay away from amps. He should know it was YOUR Moronic Finger and Pea-brain that broke a Marshall.
