Love the sound of your cat backs...forsure! Too bad by the time I'm ready to purchase (something), these will be back up over the 1000 dollar range. The axel back version sounds close to yours from what I can gather through the video on here, but perhaps with a bit less depth to them.
Agree, I hear no rasp in your vids at all!
