Agree with many that it depends on what you're trying to add to your sound without an amp. For at least 10 years now, I've only used my amp for its power section (mostly for on stage sound for me, sometimes as my sound when there was no PA). I started off with a Boss GT-10B, which was super versatile, but I found it to be too much to sort through on a regular basis - too many possibilities. I've also had a minimalist phase where I used a REDDI, which was great, but I often found myself wanting to EQ. That led me to a Jule Monique, which was also great, but then I found myself wanting to add some drive/gain. That led me to the VT Bass Delux, which has been my go to for a while now. It's about the right balance between being able to EQ and add gain, but the strength is really the character knob. I'll leave it to the Sansamp experts to detail what they like best in terms of settings, but I like being able to dial in a variety of tones depending on the room I'm in. It's about the right amount of options, size and cost for me. I have thought about the Bass FlyRig, but I really don't see myself as needing an octave and chorus, maybe a compressor though.
