I've been considering a few options for FOH...
#1
A LPF + HPF, like the one Broughton makes. I could run this in my signal, or after my signal but before a DI going to FOH.
Not thrilled about this option because I think some of the other options offer more functionality.
#2
An Aguilar TH DI. I played the TH amp for a long time, and like the tone, especially with the gain turned down for a clean tone. The AGS is very much like a cab sim. Lot's of people think it's a distortion - and it can be if you use it with the gain knob. But keep the gain low, and it's like a cab sim.
This is a graph of the TH head with the "Drive" (AGS) set at 3:00, which is about the same as the fixed AGS setting on the pedal. It looks like the response curve of a cab.
And if you don't want that peak at 2.5K, then the treble knob can take care of it. And you can use the para-mid control to really shape your sound - although maybe better to let the FOH guy do that. You can also use the gain to put a little hair on your notes (if that's part of your sound).
The only thing stoping my from going this route is a lack of I/O options. If you want the pedal enganged with the AGS on for the FOH, but don't want that in your amp signal chain, you have to find a way to split your signal. On my Streamliner amp, I could run a signal out of the tuner out to the TH, but if I wanted to use my vintage bassman, which doesn't have a DI or other out, I would have to find a way to split my signal - assuming I don't want the TH sound going to my stage rig. Not a huge deal breaker, but an unaffected out / passthrough would be a nice feature.

My third option, and I'm leaning this way (actually maybe this and the TH - different flavors), is a Q-Strip. It has all the I/O options you could want and has a built in HPF+LPF and some pretty powerful EQ that can give you that bass cab response curve. Nice looking box that is kind of a swiss-army knife type tool. Nice to have that in the gig bag.
#4
Also in the running is the Shift Line Olympic. Again, preamp with great I/O and cab sim for FOH.
I'm pretty interested in the SLO, TH and Q-strip since they both have actual pre-amp functionality (unlike the Broughton option). I could use the Q-strip with my acoustic guitar as well.
