GA-47 Extended line art

Are you looking for the same great sound as in the GA-47 but with some added flexibility? The GA-47 Extended has a removable capsule head in the same format as the vintage U47, meaning that you can use vintage heads on the GA-47 Extended or one of GAP heads on a vintage U47. It also has the polar pattern switch on the front of the microphone below the grille and an aviation style cable socket for an even stronger vintage vibe.

The standard capsule head is the GA-47 Extended HV, using a M7/K47-style vintage style capsule (our model name = S47d) with a darker tone, giving the GA-47 Extended just about the same sound as our standard GA-47 model. It can also ship with the GA-47 Extended HM capsule head using the K67-style capsule (our model name = D35d) that has a brighter and more modern tone, or with both capsule heads.
