Has anybody experience with this amp? How does it sound? Vintage or modern? I have a Rickenbacker 4003, an Ampeg 410 Heritage cab and SWR 350x amp. It's time to change amp cause of my GAS! I'm between Ampeg SVT CL and EBS 450 Classic. I know that they are different (SS and full tube). I'm looking for clear, fat and round sound.
