The only time I've been able to use Voice 1 on the Abasi set I have (which isn't too dissimilar to the moderns IME) is by removing any overdrives or boosts I have before the amp, and intentionally dialing the amp in way darker than I would normally. With a 5150 you can get some pretty cool death metal tones pretty easily. It also knocks the Clayman sound out of the park with ease.The Deep knob on Diezels can be really tricky. I've not been able to crank it past noon with most pickups before I lose clarity; actives or passives. I think the faults that the Moderns are usually accused of (anemic, thin, too middy) are actually aiding me with the Diezels. Still don't like them with my Oranges, Marshall, or 5150 amps.
On an unrelated note:
Back to my usual flip-flopping with Fishman
I still can't help but feel like I would be happier with a 707 or 81-7 in the bridge. I am 100% a passive guy, so any time I go from playing a guitar with passives back to my Fishman equipped guitar there's a bit of shell-shock. There's just something cold and sterile to them, even in the passive voice. It's just too clean and "perfect" I think. It translates to a somewhat unnatural sound that our ears aren't accustomed to. Once I'm used to it again I really don't mind, but going back and forth with guitars always fucks me up. I just need to scoop a few B-stock EMGs from their Reverb store already so I can hot swap them when I'm the mood.
