Find below some soundclips, comparing the AMT SP25B mic and the Schertler Dyn-B transducer. http://www.douglaswhates.com/misc/noodleA_AMTsp25.mp3 http://www.douglaswhates.com/misc/noodleA_dyn-b.mp3 http://www.douglaswhates.com/misc/noodleB_AMTsp25.mp3 Now, I realise the AMT and Dyn-B were designed for live work and, as such, there are a lot of compromises. Also, I know that the important thing is how they sound through a cab. But, I have to be honest - this raw sound is terrible! The Dyn-B is almost offensive to the ear and the AMT is hissy and cheap sounding. Why would I want to amplify this really bad raw sound? I'm even wondering if both these pieces of equipment are faulty...!? As a direct comparison, here's a small diaphragm studio condenser, positioned in a similar place, but a little bit further away than the AMT. http://www.douglaswhates.com/misc/noodleB_schoepsMK21.mp3 I'd be interested to hear your thoughts...
