Not intense reverb effect, but I don't think that is main purpose. Gave a nice room sound to thicken up acoustics. My main acoustic guitar mics are a WA-47 tube LDC, Shure SM81 or Byerdynamic M160 double-ribbon mic. When re-micing, it sounded nicer than expected. I expected it to be a bit muddy but they actually sounded fuller. The rooms sounded nice once I got over the "reverb mindset" and used strategically they helped my acoustics sit it the mix well
