Ok, So I've been looking around a mid-level bass heads to power my BSE410HLF cab. I've come across a Yorkville bass master xs400 at $400 which after I sell the GKbackline 600 will only cost me $200. I was just wondering if anyone had any experience with that head. I've read a few sparce reviews but i'm not getting a whole lot of info. Soooooo With that cab and an MIM Jazz what do you think? I'm looking for something that has some balls. I play in the style of most Hardcore/Metal/Crust bands such as Trap Them, Converge, Circle Takes the Square, etc. Thanks guys! Also, I'm wondering if the Yorkie can do 2 ohms? That may be important in the future when I decide to throw another cab on top of my already existing cab...Or just sell it, and get 2 8 ohm cabs.
