i use the akg, gets nice full sound i mic about 40mm from the speaker, i have used the di in the past however i much prefer to use a mic, have considered grabbing something to start dual micing but the d112 comes really close to what is actually coming out of the cab.
i actually got the akg after recording with my band liking the recorded tone we got and finding out it was the akg infront of my cab.
