I have a Hartke rig with a 3500 head and a 410XL cab. I wonder how the sound will change if I ad a 410 or a 115 cab. I want more bottom to my sound. I have pretty much treble on my eq. The bass i´m using is a Fender Jazz (marcus miller signature) I have read some of your thoughts on the 3500. And I am surprised that so many of you don´t like it. I think it´s good amp but the compressor i useless.
