Hi guys, I have the chance to buy a second hand SWR350X head for 350 dollars. The head is brand news and only one month old. I have however zero experience with SWR and although I'm interested in buying this head are there any people who could give me some adivce concerning the head? I'm not troubled with the headroom because I have three active basses (Spector, Schecter and Mayones) and will hook this head up with an Ampeg SVT 610 HLF cabinet. Thanks all in advance!!!
