I have owned a Stage 800 for a couple of years now, I think it’s a really great amp and after this time I am still experimenting with all of the settings and model options! My main live sounds are a modified model Rumble V3 plus the GK model. ... ...
Say, there, Baker, man! Good to hear from you. Please show us a photo of your Rumble in the main Fender Rumble Club thread and get a free, unique membership number!
...... The one thing I am a bit disappointed in though is the Aux In for inputting external audio devices etc for playing along to etc? Whatever you seem to plug into it (eg YouTube Audio or MP3’s) the sound is VERY thin! In live settings in addition to my bass I use my Stage 800 for amplifying my Moog Taurus pedals, but as huge sounding as these pedals are the Aux In seems to suck a lot of the tone and depth out of them. ... ...
1. Probably not the answer for more volume & depth, but some Rumblers who play music from MP3s or CDs between sets thru their combos make sure to turn on the horn for that, while during sets they mostly turn off the horn. Just FYI.
B. Page 42 of the Stage & Studio manual tells you how to set the Auxiliary Input Volume, under the Bluetooth menu, of all places. There are 3 fixed levels, High, Normal & Low, and the default allows the Master to control it. It also describes balancing the levels of instrument input and the Auxiliary device, but all settings are still controlled by the device's volume setting, too. Hopefully, this can help you?

... ... Is there any way I can use the Stage 800 ... by using the Send/Returns instead of the Aux In? I have tried using the amp’s input socket for my bass and the return socket for the Taurus but this doesn’t work. ... ...
Yes, usually anytime you plug something into an FX Return that doesn't take a signal from the FX Send then you are just bypassing the pre-amp completely and putting nothing but the FX Return into the power amp. Can your Moog Taurus pedals take the FX Send signal in and just blend their own sounds together with it? I don't any such reference in the Taurus 3 manual.
I also don't see, in a few quick searches, any posts that talk about using the Taurus in an FX Loop, or Aux Input, at all. I did see several mentions certain amps specifically for the Taurus, I assume by itself. One post says he uses different amps for bass guitar and bass pedals because they seem to interfere with each other when playing simultaneously thru the same amp.
I also found the Bass Pedals (Taurus, Roland, MIDI, Etc.) Club where you might ask this question.
Hope some of this helps.
