I had posted a couple days ago re large diaphram condensors and i was in Buffalo and i drove past a Guitar Center and they had a used Blue Firefly deluxe limited edition mic on sale and the sales guy was awesome and dropped the price a $100 to 689 and this things in mint condition. From what i understand this is the u67 capsule inside. Anyways a long story short This is a wicked mic at any price but at less than half of retail this is one incredible deal. I tried out the Neumann TLM103 and the 414xl II and none of them sounded as smooth and buttery through a mackie mic pre ( yes it actually sounded good through the mackie I do have better preamps in my studio) Definitely check out this mic!!
