i recently bought an Acme B2 series II 4 ohm. wishing I had bought two of them in 8 ohm because my head wont run at 2 ohms. If anyone has a 8 ohm B2 that they want to trade for a 4 ohm B2 I'd make it worth your while... If anyone is interested let me know and I can get pics to you. thanks for looking..
