As a longtime Walkabout lover, I used to think the mPulse 600 could not cop the WA tone.....but after having played an mPulse now for about 6 months, I know I can get the Walkabout sound I prefer from the mPulse 600, which has plenty of power through a pair of 12s for my needs. YMMV, of course, and we all may be seeking slightly different flavors from the Walkabout, so there's that.....
My Walkabout through LDS 15/6 and true fEarful 12/6 experience was mediocre. I don't care for the match. Again, YMMV.
So, if you don't mind me asking, how did you achieve the WA sound with the mPulse ?
