The WA-87 is based on a classic 60s circuit that is widely considered to be one of the greatest studio microphones ever designed. The new WA-87 R2 uses top-quality components like a NOS Fairchild transistor and high-bandwidth capacitors from Wima. The WA-87 R2 uses a custom-wound Cinemag USA output transformer like the original WA-87 did, with the new version providing a slightly increased output level and improved frequency response. Its also employed the same capsule the WA-87 uses, which was designed to the exact specifications of the ones found in the vintage mics. The result is an accurate sonic replica of arguably the widest-used studio microphone in popular recording history!
