@Berthos, sorry for the delay in my responding to this query.
I have used Logic Pro X (LPX) as my primary DAW for several (4+) years.
I also own the Rumble Stage 800. The Stage 800 is the big brother of the Studio 40 you’re considering; but, from a modeling and USB/analog line out standpoint, they are identical.
I am at a bit of a disadvantage in discussing this in significant specific detail right now, as my MacBook Pro is in the shop for repairs. So, I can’t reference the amp plugins and give you a model-by-model comparison; but, I
can speak of my history and experiences in general terms...
When I initially started using LPX, I used the Apple amp plugins that ship with the app and S-Gear amp plugins from Scuffham Amps. I found them both to be capable; but, somewhat limited. I don’t think the gain and overdrive functions resemble real amps well as newer modeling technology does, nor (of course) as real amps do.
My only bass amp at the time was an old Line 6 LD-150 modeling amp. It was a nice amp for general usage in very small venues; but, its older modeling tech was a bit limited. It was still functional for recording via its analog line out into an audio interface. So, I used that amp when possible, and the plugins when more signal processing was necessary.
Not long after, I picked up a Fender Bronco 40 (
the spiritual and technological predecessor of the Studio 40). It came with 9 amp models and a modicum of effect. For deeper programming, it leveraged the Fuse app. It also had a USB line out; so, you could just plug it into the Mac or a USB hub, and LPX recognized it as an audio input. No audio interface required. I loved that little amp. Indeed, I still have it and use it from time to time for informal jams.
But, time moves on; and so does Fender. New tech emerged. Support for the Bronco series (and the older Mustang amps) and the Fuse software waned.
At end-2018, I was doing a lot of home recording. I was also in a band for which I supplied the PA, which was capable of supporting me playing with IEMs and no amp. Being a strong supporter of amp/cab modeling, and having been really happy with all my old Line 6 gear, I purchased a Line 6 HX Stomp as my primary “amp“ for both live and studio use.
I am
really happy with the Stomp. My only complaint is its (current) 6-block limitation. But another item it lack in features, is that it makes no sound by itself...
Time marches onward. I left the aforementioned band, and joined a blues-rock power trio. The BL is old-school. Loves his powered mixer and passive speaker/monitor setup; but doesn’t run anything but the vocals and some kick through the mains.So, I needed an amp that’ll work for me in any venue short of a sound company doing the house.
Enter, the Fender Rumble Stage 800.
I really like this amp. I initially got just the combo; but soon added the matching extension cab. Wow, talk about power! And features...?
The current firmware ships with 20 amp models, 26 cabinet models, and over 50 effects. Analog line outs for audio interfacing; digital line out for (stereo or mono) input directly via USB. Integration into LPX could not be simpler or more functional.
So, from my experience, these are my thoughts and suggestions...
Although, amp plugins lack the fidelity and subtleties of real amps and leading modeling tech, they are certainly good enough to be usable; especially for the bass. (
I hate to say that; but, the truth is, bad models are much more apparent on guitars.)
One powerful advantage that amp plugins offer is the option to “re-amp”. That is to say, your are recording the signal before it hits the amp. If you decide later you don’t like it, you can change amps. The HX Stomp offers very a similar option, in that one (pair) of its USB outputs is a dry, unboosted signal that (
if recorded) can be reamp’d via a USB input into the Stomp. The Rumble Studio/Stage cannot re-amp. There is no USB input channel into the amp.
However, the advantages of the Rumble Studio (
and Stage) are: all the excellently modeled amps, cabinets, and effects; light-weight portability; analog and digital connectivity; and the fact the amp can be fully programmed both within the Tone app AND via the front panel. (
No concerns about ongoing app support.).
But, the biggest advantage is...
It sounds great when you turn it up, all by itself.
You don’t need to run it through a computer to hear it.
So, my suggestion is: Get the amp. You’ll love it.
And you’ll always have the plugins if you have reason to use them.
TL;DR: It’s not too long. Read it from the top.
Hope this helps.
