Description Do you love the sound of your tube amp cranked up but can’t find a place to play that loud? Or do you need to record without blowing the mics, or the neighbors away? Well, this cool new product from Groove Tubes will allow you to keep your high powered amp with all it’s tone and feel while reducing the power by as much as 75%! It allows you to “substi-tube” the high power 6L6 output tubes with the lower power EL84. It also converts the amp into a Class A design further reducing power and increasing the “grease” factor.
