Fender Rumble 40 V3 Bass Combo Amplifier
The Fender Rumble 40 V3 is a significantly different amp compared to its smaller sibling, the Rumble 25. While the circuit itself is the same, there are extra controls to change the amp’s voicing. The key to the versatility this amp possesses are the EQ switches. The amp has a contour switch (changes the mid-range profile), vintage (gives the amp a warmer tone), and bright (enhances the high-end). When one of these switches are engaged you can use the EQ knobs to further change the amp’s tone.
- 10” Speaker
- Controls: Bass, Low Mid, High Mid, Treble, Gain, Drive, Level, Master, Contour, Bright, Vintage
- AUX-Input, Headphone-Output, Footswitch, Line Out
The Fender Rumble 40 V3 has a 10” speaker. While this is on the smaller side, the amp still has a reasonable amount of depth and warmth. The 10” speaker also gives the Rumble 40 a punch that it would otherwise be lacking.
The volume and overdrive controls for the amp are a bit odd, with the Master control dictating the overall volume and the Gain control deciding the base level of gain. The amp also has a gain boost in the form of an overdrive circuit, which is controlled by the drive and level controls.
The 40 V3 comes with an AUX-input as well as a headphone-out, and it has an XLR line-out. Basically, this allows you to plug the amp directly into a P.A. So while this amp isn’t loud enough to gig with on its own, the inclusion of the XLR-out makes the wattage of this amp a non-issue in many situations.
We were recommending the Rumble 40 V3 until we performed a major review of the category in August 2018 at which time we found there were more highly rated options to recommend which you can see in our guide to The Best Bass Amps - Combo Under $500.
