Vintage Vibe with Modern Features!

Fender gives bassists of all levels a solid amp that can handle anything. Plug into the Fender Rumble 40 for serious bass tone in a compact package! This black beauty offers a basement-friendly 40 watts, complete with both gain and blend controls in the overdrive section, so you can bring the perfect amount of overdrive into your sound. In fact, an optional footswitch is available that lets you easily bring the overdrive in and out whenever you need some extra tonal tenacity.

Fender Rumble 40 Bass Combo Amp at a Glance:
  • Sound-shaping and more
  • More than just a solid performance tool
  • A single 10" speaker for serious punch
Sound-shaping and more

The Rumble 40 combo's 4-band EQ helps to shape your sound, and the 3-button voicing palette sculpts the sound further. Choose between bright (adds a treble zing to the sound), contour (low-end boost), or vintage (classic bass tone with deep lows and vintage character). These give you a ton of flexibility to find your signature sound. The XLR line output can pump the tone you love straight into the PA for bigger gigs. This will make your sound tech happy, since it'll greatly simplify getting you pumped into the PA. Need a little extra teeth for a particular song or passage? The Rumble 40's built-in overdrive has your back. Get the optional footswitch for instant onstage convenience.

More than just a solid performance tool

The Rumble 40 combo isn't just about performance, though; it also helps you practice. It's stuffed with a handy aux input that you can plug your iPod, laptop, drum machine, or other practice gear into. And there's an 1/8" headphone jack, so you can practice late into the night.

A single 10" speaker for serious punch

Fender loaded the Rumble 40 with a single 10" speaker - the perfect choice for making sure your bass punches through the mix.

Fender Rumble 40 Bass Combo Amp Features:
  • Basement-friendly 40 watts
  • Single 10" speaker delivers serious punch
  • Vintage vibe with modern features
  • Footswitchable overdrive for extra aggression (footswitch available separately)

Bass Amp

Thanks Craig for turning me on to this amp. It is bad to the bone
by JAMES BRANDENBURG from PUNTA GORDA, FL on

Does Size Matter?

Not when it comes to the Rumble 40 by Fender. First, I'm a six-stringer guitar guy with very minimal time spent thumping on a bass over the past five-plus decades. Recently I joined a church music group playing an acoustic-electric guitar and singing, but ….. about once a month or so, I've been subbing for the group's regular bass guitarist when he's out. So, a few weeks ago I picked up a Hofner Ignition series "Beatle" bass for church and home recording. After having my tech swap out some of the cheapo China-made parts for German-made parts and doing some corrective fret work and a set-up, that thing really feels and plays and sounds great. When I went to pick it up, I had the chance to test it through a Rumble 40. It blew me away. I had been looking at them on-line for a while and was split between the 40 or 100. In the end I settled on the 40. The 10" speaker really has so much punch. The Hofner has a deep bottom end, anyway, so for me the 10-inch speaker is a better match for a violin bass than a 12-inch speaker The other selling point is that this has an XLR line out that can connect to a PA if you are in a larger venue needing more power. But for my needs — church, small venues, recording, the Rumble 40 is more than enough. So many people are calling it a perfect practice amp — which it is — but, I do think it is much more than that. Finally, 18 pounds? Are you kidding me? I love that number>

Great little amp

I've had the Rumble 220 v3 for about a year and love it. While it's not heavy (32lbs) it is a little bulky.
I'm 65 with arthritis in my shoulders and right hand so carrying the R200 up my basement stairs (where my music room is)
Taxing but not impossible. For a gig or an outdoor event I'm happy to do this, but for rehearsal and playing at church I needed something lighter that still sounded great with decent volume and an xlr out..
Enter the Ruble 40 v3. This little 18 pounder is just what I needed for rehearsal and smaller gigs.
I wouldn't hesitate to recommend this to anyone.

Great Bass Combo at good weight to move

I bought this for practice and it works great with good sound and power. Lots of ways to adjust for the sound you want. Light enough to easily move at home or on a gig.

Fender Rumble 40

A big "Thank You" to Tim for helping me purchase an amp and gig bag or our 12 yr. old son It arrived right on time, we are very happy with the products. The amp sounds great and has enough power for him to jam with a drummer. The gig bag is padded and allows him to transport his bass to and from school. I would completely recommend Sweetwater

It’s impossible to imagine a world without Fender guitars, and if you’re like many of the guitarists at Sweetwater, then Fender not only made the first guitar you ever bought " they made the last one too! From building the first mass-produced solidbody electric guitars and basses in the 1950s to creating some of the most influential amplifier designs in history, it’s no wonder why Fender is one of the biggest names in the business. As one of the world’s largest Fender dealers, we have countless guitars, basses, amps, effects pedals, and accessories in stock and ready to ship, whenever you need them. We’re always getting our hands on their latest creations, and there’s nothing we love more than to tell our customers all about them! So, whether you’re looking for your first axe or a Custom Shop creation, make sure to give your Sweetwater Sales Engineer a call at (800) 222-4700.
