We've talked a lot about the contour curves and the EQ here, but we've not really touched on subtractive EQing.
I was practicing last night with my MG800 and headphones, and I was using my Pawn Shop Mustang bass. The humbucker has a funky midrange and with most amps/cabs that add bass and low mids, it's not noticeable. But with the MG800's clarity, the funky mids on the pickups really jump out. So I did a bit of subtractive EQing - dialed in the odd frequency and pulled down the mids - and it cleaned it right up. After that, I got thinking and turned down the bass a bit and I got this really cool, gnarly tone from the Mustang. I haven't clipped my nails as I usually do so I was getting a bit of bite with my fingers and having a blast jamming out.
My default setting is always to use the EQ to enhance the sound by boosting certain frequencies, but there's just as much power (maybe more) in pulling down the unwanted frequencies. Because the mid sweep on the MG800 has such a huge range, I was able to dial out the odd mid frequency and still have some balls with the tone.
Jeff - this thing is filled with surprises that just keep coming. I can't speak highly enough about the amp, although I daresay I'm trying!

I had a similar experience at rehearsal with my R&B band last night. I put Fender CS60s pickups into my MIJ Jazz and they have a very rock-oriented, snarly midrange. Normally, I like that but it's overwhelming for my Motown/R&B group, even with flats on the Jazz. The flats actually seem to make it worse, accentuating less highs and more upper mids.
So, last night, after I plugged in and remembered the nasty tone from the last show (EQ flat, Counter B off) I did with this bass, I dialed the mid freq sweep up to about 2:00-2:30, cut the mids back to about 10:00, then ran Contour B up to about 11:00 to bump up the low mids. Left bass and treble flat. Instant old-school smoothness, but still enough cut to be heard clearly (using the MG112). The contour and semi-parametric mids really give a lot of sculpting ability to dial in/out what is needed. It also really adapts well to different instruments, as I would never consider running the EQ this way for my Stingray, but it's perfect for the Jazz with those pickups.
