I just got this bad boy in today and was messing around with the patches on my Zoom MS-60B and decided to try something different from what I had set up. The MS-60B took the place of my Sansamp BDDI and pretty much filled the needs of all other effects that I could "sparingly" use. The one thing I didn't really like about the MS-60B was how the higher frequency, treble, on some of the preamp models like the SVT would sorta hiss and sound a bit digitally. I play with a small Acoustic practice amp at home and use a Peavey Firebass and 410 Yorkville cab at church and DI to the FOH. What I did different this time with the Mooer Micro DI was to engage its Cab sim and turn the cab sim off on the Zoom MS-60B. What a difference! The highs were not hissy or digital sounding and the lows just sound massive now! I don't know much about speaker/cab sims but now I know that they are a great tool when going DI!
