Blue Microphones Bottle Custom Shop Flagship tube condenser. Incl. B6 cap (choice of 6 colours)

Select from Limited Edition Colours


The Blue Microphones Bottle Custom Shop Flagship tube condenser mic comes in a choice of 6 limited edition colours (outlined in the photo above). It also includes a super versatile B6 Bottle-Cap – allowing you to capture a number of different sources in premium quality audio.


It offers high-quality cardioid recording with more defined lows and a welcome high frequency presence. The design is based on premium vintage tube microphones, but with modern benefits that rectify the issues faced by their classic counterparts. For example, custom ceramic tensioning rings remove the dropout that the older models were known for. A punchy tone in the both the low and high frequencies is delivered due to gold sputtered film – producing robust, modern recordings.

It is particularly good for capturing backing/lead vocals and voiceovers. It’s also suited to percussion, piano, accordion, clean guitar and even distant room miking.
