I was excited to see that UAD released a guitar amp simulator but it turned out to be a very poor sounding. Unfortunately the plug in is not only far from the ENGL amp, but also very far from any gutar amp. The sound is very dull, can't hear any valve sound in the signal path. I think that the worst thing is that it doesn t "feel" like a guitar amp. The "delay" though is very, very well made. I don't know if it was a bad moment of UAD or it is that the plugin was developed by Brainworx, but I think that the company should consider twice before releasing a plugin with such a poor sound. I love all the others plug ins I own from UAD and I think its the best sounding plugin system, and it's a pitty to hear somithing so mediocre like the ENGL.
