The reverbs were used on classic recordings by the likes of Prince, Radiohead, Pink Floyd and others. "The EMT 140 and EMT 250 have inspired generations of great recordings, and we're excited to bring them to even more creators." Both the EMT 140 UAD and the UAD EMT 250 are compatible with macOS and Windows and do not require Apollo or UAD hardware. Pick up the EMT 140 here and the EMT 250 here. Back in April, UA released a free bundle comprising eight of its most popular plug-ins, including the "easy-to-use" Pure Plate Reverb and the classic 1176 compressor.
