The Flea M 251 is a meticulous recreation of the legendary Telefunken ELA M 251 tube large diaphragm condenser microphone. 

The Flea M 251 features Tim Campbell's CT12 capsule, a replica of the edge-terminated, gold-plated CK12, and carefully selected 6072A tubes. The FLEA M251 also includes Flea's identical T 14/I transformer clone delivering the unmistakable sonic character of the microphone.

All wiring is based on the last upgrade made by Andreas Grosse, and all connecting parts, pins and terminals are gold-plated, ensuring the best performance and lower noise.
