I've been offered an (8 ohm) Ampeg SVT-210Pro cab in a trade. I would be pairing the cab with a Behringer BX3000T and an Avatar 4x10 (4 ohm) cab. I know little about these matters at the moment sadly and I'm wondering if they would pair up well and if anyone has any experience with a similar setup or even with just the Ampeg cab. Basically, I need to know if the setup would work and if the Ampeg cab is worth acquiring and if the 4 ohms and 8 ohms difference will present a problem. Thanks for any help.
