Hey everyone, just wanted to check in to give an update on the Rumble Studio 40. I have just started exploring all the tonal options with this lil combo. I've mainly been using it as a headphone amp, which I must say it sounds quite nice via cans. The models and effects may not fool tube-purists, but I think they do a pretty good job overall emulating the basic sonic footprint of the several amps. Having neighbors, I have not been able to play the amp at volume very much. I will admit, the sounds I'm getting via headphones sometimes do not translate as well the same thru the speaker itself. Of course, the speaker/amp of the combo adds its own signature upon the live projected sound. Some of the presets cut through a lil better than others. What may sound thick and defined thru cans, I've found can require some eq adjustments to reach my desired live/amplified tone.
Having played a basic Rumble 40 before, I think the overall performance, and inherent power feels roughly the same. I must stress that the Studio 40 is not an amp for folks with big gigs or loud rehearsals (without pa support or run into the effects return of a bigger amp & cab setup). I'm still very much in the market for a 500 watt + amp. While 40 watts is not whisper quiet, I just happen to love the clean headroom/cushion a bigger amp/cab setup can achieve. If you're content with the simplicity of the current Rumble 40 and not a big effects user, you may be satisfied with just adding a few of your personal favorite flavors of stomp boxes. That said, if you enjoy having a box of colors to play around with different sounds in one package, this could certainly keep your creativity busy/entertained. I do feel that in order to get the most out of the Studio 40 (and the Stage 800) & best utilize whats on board, the optional purchase of the Fender 4 button footswitch would likely be recommended. For my purposes, I may be content just turning a few dials/creating some presets without needing the footswitch.
On a final note, I am glad there are some presets to jump in for reference points. After fiddling around with the various amp, cab, effect, and speaker sims, I found myself getting a bit lost at times with seemingly endless possibilities, with some interesting (and some less-desired) outcomes. I typically gravitate toward "plug n play" creative tools. This amp can do simple, but definitely encourages exploration as its strong suit. IMO, the existing basic rumble line is the definition of simplicity, which can be a very good thing for quite a lot of players. While some of the amp sims are more pleasing than others, I've actually found the more traditional "effects" such as reverb, delay, synth, organ, chorus and vibrato to be more convincing than I first expected. Some of these effects might come in handy when recording, but I would likely try running the Studio 40 into a more powerful amp/cab setup to get an optimal miked/live tone for my purposes. Overall, I feel the Studio 40 will serve as a nice practice tool for me when I don't need sheer volume/impact and finding new sounds is my primary goal. I would be curious to try out a more efficient speaker to get the most out of the 40 watt amp like Astro Sonic did, but plan to keep it ‘as is’ for now. I'd still highly recommend playing one in person if possible before making a decision to pick one up. I can see the versatility appealing to some players, but it may also offer more on tap than others will need. This is my first time experiencing certain effects with bass, so the novelty is fairly fresh yet interesting to me. I'm not sure how many of these effects will find their way into "my sound" but its cool to try new things.
