i ' d say you need to learn the speed of the rocket , and how to lead your targets . use trwalkway for that . <| sep |> Nothing ' s coming up for me . <| sep |> I ' ve heard that the watts rating is based on the point where the power amp starts to distort . On a tube amp the power amp distorting is a desired effect , Neil Young wouldn ' t exist without it and none of us wanna ponder that world . That amp that starts to distort at 20 w , and thus rated at so , is just getting warmed up . literally . and has much more volume to offer . With a solid state amp you want the preamp to do ALL of the distorting . Power amp distortion isn ' t musical at all . So , because of that difference , there are 15 w tube amps that easily drown out 50 w solid state amps .
