Rumble 25 V3 Bass Guitar Amplifier, 25-Watt Combo Amp with 8" Speaker, Switchable Overdrive, Mid-Scoop Contour, Aux In & Headphone Out, with 2-Year Warranty

Let me start by saying I just needed a small, light weight practice amp and this one fit the bill for the price. I have been playing bass for about 58 years and have a large rig 210-115 GK set up but didn't want to break that out every time I wanted to play on the porch, office or a buddy's house. The little Fender Rumble 25 is super light and the right size to move around. After unpacking the amp I noticed the workmanship was first rate so I plugged it in and hooked up a bass. Sounded OK but not what I expected. Pulled the removable grill off and noticed a very cheap speaker and a 3" port in the front that wasn't tuned, but for 99$ what the heck. Played some more and It just sounded cheap which it is. I wasn't expecting GK or SVT sound. I immediately went to ebay and bought a Celestion NEO 8" driver with a 2" voice coil for 55$ and it arrived today. I took the grill off and removed the Fender speaker and noticed how cheap is was and noticed too that the cabinet was hollow, no damping material so the insides of and old fiber filed pillow was sacrificed and the cabinet stuffed, also I cut a piece of round hard foam to fill the port. Put it all back together and now we have an amp. Real nice lows and great tone all through the different ranges. That did the trick. I know what you're thinking, this guy bought a 99$ amp and spent 55$ more to make it work when he could have just bought the 40 with the 10" speaker, but I would have had the same, but larger, cheap speaker for 199$. This now sounds great with a modest upgrade and the Celestion NEO is a MUCH better speaker that makes a small amp sound really good. 160$ total, light weight, nice controls, and that great Fender styling. Sorry I'm a purist and keep can't leave well enough alone and this was a small price to pay for a now great sounding amp, and by the way the pillow is pleased it went to good use. I gave it five stars for 99$ but now it's 6 stars.

The Fender Rumble 25 V3 is an amazing little bass amp! The 8-inch Fender speaker delivers rich, punchy bass tone, and the overdrive circuit adds just the right amount of grit. The three-band EQ and contour switch let you dial in your perfect sound, and the top-mounted soft-touch knobs make adjustments easy. Compact but powerful, it’s perfect for practice or small gigs—and knowing it’s backed by Fender’s 2-year warranty gives extra peace of mind. Highly recommend for beginners and seasoned players alike!

This is a fantastic bass amp at a really good price! Nice clear sound with no background noise. Way better than I thought it would be for the price!

In this article from the New Yorker, January 28, 2013 “Music To Your Ears.” Daniel Levitin (https://en.wikipedia.org/wiki/Daniel_Levitin) “pointed out that most of the lowest notes on most pianos are actually inferred rather than heard. The soundboard on most pianos isn’t long enough to produce the bottom octave, but the brain hears the right overtones, which the piano can produce, and neurons in the brain begin to fire at the frequency of the missing bass note.” In days of yore (1950s – 1960s) this psycho-acoustic quirk was used in the design of “hi-fi” consoles to produce a semblance of deep bass without actually having an extended low frequency response. And so it is with the Rumble 25. I measured the response of this combo as shown in the graph. The red curve is with all controls set to 12 o’clock. The blue curve shows it can actually produce a reasonably flat response from 90 Hz to 2.5 kHz, +/-3 dB with the controls set as follows: Bass @ 12 o’clock, Mid @ 9 o’clock, High @ fully ccw. This means that it can only reproduce the 2nd harmonic of the lower bass octave (40 Hz to 80 Hz). Because of the normal 18 dB/octave roll-off for a vented enclosure, the 10 dB down point is about 70 Hz. As to the 2.5 kHz frequency, note that the 12th harmonic of a high A (220 Hz) on a bass is 2.64 kHz. The driver is low compliance and the box appears tuned to about 100 Hz, both of which are consistent with the measurements. These curves are smoothed with a 1/3 octave cepstral algorithm to remove insignificant non-audible variations in the measurements. There is a large resonant peak just over 3 kHz = 1/2 the driver diameter. This is tamed pretty well with the High control fully ccw, but still sits almost 7 dB above the average level. Given that the paper cone is quite stiff with no attempt in its design to damp sound waves travelling through the cone material, this resonant peak is not at all surprising. This peak corresponds to the 16th harmonic of the 220 Hz high A on the bass. This peak is probably a good “feature” for the attacks of slap bass (which I don’t do). Otherwise it is actually of little consequence. All this said, the Rumble 25 works well for me. It was low cost, is small, lightweight, and, in spite of lacking any usable output much below 100 Hz, it nonetheless “sounds” like a decent bass loudspeaker. With the controls set as noted for the flattest response, it works well for both my electric and acoustic basses, both of which sound best through a flat response system. The former is an all-original, ’63 Fender Jazz and the latter uses an NS Design “Copperhead” pick-up, a prototype kindly given to me by Ned as a present for mentoring one of his sons on bass. For acoustic gigs, even those using a PA for rooms sized for around 75 -100 audience, the Rumble 25 does the job in terms of sound quality and loudness. For larger rooms and louder gigs that’s why I have my “big” rig. This is custom set-up with a ruler flat response from 40 Hz to 2.5 kHz. However, It consists of a separate EQ, amplifier, and loudspeaker = much more to set up, is five times heavier, and it cost over 20 times more than the Rumble 25. That is what prompted me to try the Rumble 25 for smaller gigs. For what it's worth I play most all genres of music from classical to rock. One feature I like is Fender's built-in, non-adjustable, "Delta-Comp" limiter. This seems to work really well, holding things in check when the amplifier is over driven a bit. Push it hard over the limit point and some high frequency artifacts do appear. However, when running the amplifier near its limits it is virtually unnoticeable except for subtlly limiting the loudness. In spite of its measured performance, I'm giving the Rumble 25 five stars because its doing just what I need it to do.

Perfect amp for home practice

I'd draw another few stars on this page if I could. I got this amp so I wouldn't have to lug around my huge bass rig for a quickie jam session elsewhere. Didn't have high expectations for the size and price. As a bass practice amp, it's just fine. Surely comparable to any of the other offerings out there. Plenty loud and a surprising amount of range to that little 8" speaker. For the price point, it's a lot of amp for the money. Nice and light, small, portable, everything nice quality. Not quite loud enough to gig a bass with, but pretty decent for most anything else. The real surprise was how good this thing is as a violin and guitar amp. I had been struggling to get a full sound from my NS Designs 5-string violin played thru a Fender Blues Deluxe combo amp. Everything was pretty screechy and that made me sad. Sticking my violin through the Rumble 25 was a revelation; everything I always wanted to hear from my violin came straight through. Full, rich tones. And furthermore it was loud enough to gig with! I played my violin through this amp at an outdoor block party with full band and PA setup, and it came through with more than enough power. Didn't even need to mic it. But wait, there's more! It also excels as a guitar amp. A very no-nonsense, full presence kind of tone with more than enough bottom end to make a Fender Strat sound fat even on the bridge pickup. (I'm selling my Blues Deluxe now, shhh don't tell Craigslist) This thing is great if you're a multi-instrumentalist. I suspect it does pretty well as a keyboard amp too.

This amp is incredible. I am a big fan of it. I play live shows with an Orange bass amp and use this Fender 25 bass amp at home and for home recordings. I have to have it on the lowest possible volume, it is so powerful, to not disturb neighbors. You could definitely use it for small venues and cafes. Sound, carry-weight, appearance, user options, everything is great on this Fender 25 bass amp! It is about half an arm deep and up to the knees tall. It's the best for price, sound, and size! I have had my first one for several years and it is still perfect. I bought another one for another location. I wanted to try a new product, but after sampling many other brands, none were as good for this price/size category of bass amp.

Wow, so I live in a small apartment in a building with paper thin walls. I got this little amp and a bass, an electric piano, and electronic drum kit. I was worried this little 25 watt amp wouldn't be loud enough for the bass,, but when I got it and plugged every thing in it was soooo loud! then I went to sleep, woke up and tried it again, at half volume level, this thing is perfect. Everything worked out great, and I'm jamming with my neighbor and some others soon. Good deal.

Best bang for buck bedroom amp. Quality sound production and depth of bass. Do it!

Lots of sound from the 8” speaker. Easily keeps up with the band for smaller/quieter gigs. Perfect for playing along with acoustic instruments. Easy to move - lightweight. EQ controls work well, along with overdrive and contour. Great deal all around.

Le encantó a mi hijo. Actualización: Fender se ha caracterizado por ser una de las mejores marcas en el ámbito musical y sigue siendo de las mejores. Recomendable para quienes empiezan en la música, les aseguro que no se van a arrepentir. 😍

This is a very well built unit and quite loud! If you're looking to use this at home then I'd suggest go for a lesser powered one as this is too loud for home. Small gigs in open spaces is where this will shine! Am totally satisfied with it, its build quality, quality of sound and overall fit and finish are all top notch! It is heavy though but if you're not moving it too much then it won't be an impediment.

Excelente calidad
