Notes: Tube condenser mic; name/marketing position it as an affordable take on the classic Neumann/Telefunken U47 (third-party coverage quotes Gauge describing it as having 'the warmth of a tube 47 and the presence peak of a C12') -- this classic-mic comparison is NOT stated verbatim on the current gauge-usa.com product page itself, flagging as inference from naming convention and press coverage (happymag.tv, Vintage King listings). Uses EHX 6072A tube, not a vintage VF14M. year_intro (2009) sourced from third-party retailer/press pages, not gauge-usa.com itself -- flag as inference. Country of manufacture not stated on this product page; company About page states mics originate from a China-based manufacturer with US-based QC/development -- left blank per no explicit statement on this SKU's own page. Includes briefcase, power supply, shock mount, windscreen, carry bag. Equivalent noise level 18dB(A) also reported but not requested field.
