I bought these 5670’s from Amazon. None currently in stock
As far as which do I prefer? Don’t know yet. I am leaving the 396a’s in until the socket savers arrive. These are just too difficult to swap as there is very little to grip above the amp case. I do remember I liked the 5670’s quite a bit and initially was not too impressed by the 396as. They may have broken in though. The bass guitars are clear and articulate. The drum solo from Moby Dick (led Zep/Bonham) was there with all of the detail and tones. Apparently I’ll be swapping sometime between 02/15 and 03/24 Ebay/China shipping time.
