Coming from Blue Microphones, it's no surprise that Robbie comes in a distinct looking form factor that looks like a... robot toy.

But the premium price tag is an easy giveaway that this is no mere toy, rather Robbie is their flagship tube mic and instrument preamp.

Inside this preamp is a class A tube circuit with an ECC88 twin triode, that allows for high gain, while it's zero IC architecture keeps unwanted noise at bay.

The Blue Robbie's crystal clear sound continues to impress users, with many reporting that it exceeded their expectations. Build quality also gets a lot of thumbs up, while others are happy with how easy it is to use - considering the improvement that it adds to the overall sound.


While its distinct form factor got a number of commendations, there are a few users who find its shape to be awkward, and wish that it came in a more compact form factor.


The Blue Robbie's combination of distinct visual appeal, simplicity and premium sound quality makes it a good addition to any studio.
