I've been lurking on this thread for a few months and I can't stand it anymore -- I just ordered one. It should arrive next week. I'm not going to have much time to play around with it before our next gig so I need some help. I'd appreciate it if you "experienced" users would give me a starting point with settings that you like. We play mostly classic rock, so I expect to spend most of my time on the vintage channel. I play mostly finger style, but occasionally with a pick if the song calls for it. I was thinking of using the channel switching to compensate for the volume difference between using fingers and using a pick. Thanks for all the reviews and info contained in this thread. It has been very helpful.
I think you're gonna love it Thrasher. After 7 months of gigging in my classic rock band with the 100T and a 410 Neo, I find more to like about the rig every time I use it. IMO it's the perfect amount of tube power for small/medium club gigs with no FOH support for bass, as matching volume to drums puts it right in that sweet spot where the power tubes just begin to sing. And for larger gigs with FOH support I have had no problem generating plenty of stage volume. I generally use the vintage channel with my flatwound-strung G&L L-1000, and the overdrive channel for my roundwound-strung Jack Casady Epiphone.
With my passive basses the vintage channel's preamp begins to distort just above 6. On most gigs I wind up with preamp volumes at 5 or 6, master volume at 5 or 6. The flat setting on the passive tone stack, compared to the overdrive channel with it's eq in center detent positions, is approximately 10-10-7 (or 8 on the highs, I can't quite decide), though I usually start at 6-6-4 as that gives some pseudo 'boost' if needed. Even if you set both channels' eq's flat and match the volumes, there is still a distinctly different sound between the two, with the overdrive channel having a 'faster' sound.
I personally love the voicing of the 100T matched with the 410 Neo, so I generally don't stray too far from the flat eq settings on both channels - sometimes backing the bass down a couple notches on the vintage channel and pulling out the bass knob for bass boost in rooms with a bass suck, and usually cutting mids just slightly, probably around 250-300hz, and cutting highs just slightly on the overdrive eq. That's all according to taste of course so YMMV.
All this love, and I haven't even played with over or under-biasing the tubes yet, and there'll be a lot of variation there to be explored.
