After downloading some great captures for my Nano Cortex (Aguilar AG, 751, TH, Walter Woods, Capo, Sansamp, Ampeg SVT, Flip top...). I've been using those and the captures I made of my Tone Hammer lately. The wide range of tones and patches from a digital rig really comes in handy when I need to add some funky distortion/fuzz and/or need to do last-minute key changes where I've worked out parts incorporating open strings.
On a few occasions the digital capo functionality in the NC saved my tail when we switched from a male to female vocalist and the key signature of the song changed drastically. We did a song last weekend where I was already in drop-D and then due to a vocalist changed before run through, I needed to pitch shift the whole bass down to drop B, and it sounded surprisingly good.
I have dialed in the Tone Hammer patch or a Capo (not the device you clamp on the neck) preamp capture in pretty well on the NC and have A/B'd it a lot with my standard Cali76 + Tone Hammer rig, and it's very close.....Without a direct comparison to my analog rig, it sounds really great.
That said, my analog board with the Cali76 + Tone Hammer is still the reigning champion.
