Hello, I recently upgraded my setup to and SVT3 head and SVT410HE cab, which I bought secondhand. I thought that this would be enough to compete with a 100W Marshall head and cab set on 5. I've still had to crank my amp to come close. Is this normal? Does the level control on the back of the cab do anything? Is it my eq (everythings on around 5)? Am I using the wrong speaker connection (I'm using the weird looking one, not the usual jack-jack speaker cable)? If anyone can help me out it would be greatly appreciated. Thanks.
