Yeah, like I said, great for rehearsals and - as advertised - for studio usage.
Great selection of input and output options. Great idea that you have WiFi and Bluetooth connectivity. Actually, WiFi connectivity was very dodgy. Didn't work at all with the first one they send me, the second one worked but occasionally has problems with finding the WiFi throughout the update process. What did the trick for me: Try tethering via your smartphone, obviously the Fender Rumble Studio has problems with accessing some WiFi networks for unknown reasons?
What's a little bit annoying is the fact that you can use the Fender Tune app only, when the firmware is updated on the amp (cf. the connectivity problems). The app itself is great, let's you modify every aspect of the amp modelings and pre- and post-effects in the different presets. Comes along with 100 default presets and 100 slots for user-defined ones, which is more than enough imho.
The quality of the amp modellings and effects is very high. I specifically like the SWR redhead (that's why I came to this amp in the first place and the Fender amps. I didn't really dig the RockinPeg setting, seems to be very hard to produce a clean sound with it.
Just bear one thing in mind: All presets have notable differences in volume and perceived loudness. It may differ from bass guitar to bass guitar. Obviously, this is catered to passive Fender basses, for my active basses from popular Japanese brands, I have to adjust those settings accordingly. That's where the user-defined presets come in: Just create setlists in the Tone App for each bass guitar and add modified versions of your favorite presets there.
Overall, a great amp, big value for the money. Like other reviewers said, some Watt more would have been great to also make it in very load rehearsals or even small stages. And also very important: This is a very lightweight combo! Very good for your back
