Rivera RockCrusher

Okay the review of this unit is based on gigging and not playing at home. My stage rig consist of a mesa roadster 2x12 coupled with a TC Electronics G system. Needless to say the mesa can get crushingly loud when the volume gets around 11 or 12 o'clock. The problem i was having is our band has a crazy low stage volume due to using in-ear monitors and electronic drums and a sound guy who is whiny when we turn up. But most of you know playing a tube amp at super low levels just doesn't get it done. So I purchased the Rock Crusher from sweetwater before our last gig to try it out and the only thing I can say is wow. First words out of my sound guys mouth was " What are you doing differently". Most fun I've had at a gig in a while. The amp finally sounds the way I always wanted it to. The Rock Crusher is a keeper.

as advertised does exactly what it's supposed to do!!! no tone loss

Well Made

"This unit performs as advertised. It certainly cuts the DB without affecting the tone of your system. Solid construction. The one thing that disappoints me is that it only has a 16 ohm and 8 ohm setting. If this thing had a 4 ohm setting, then I could use it in my current configuration. All of my tube amps have a 4 ohm setting, for a reason. As it is I had to reconfigure my speakers and run everything at 8 ohms, not optimal. Give the ohm switch a 4 ohm setting and this thing gets 5 stars.
