Get to know them!

Fender gives bassists of all levels a solid amp that can handle anything. Plug into the Fender Rumble 100 for serious bass tone in a compact package! This black beauty offers a basement-friendly 100 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 100 Bass Combo Amp at a Glance:
  • Sound-shaping and more
  • More than just a solid performance tool
  • A single 12" speaker for serious punch
Sound-shaping and more

The Rumble 100 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 your signal into the PA. Need a little extra teeth for a particular song or passage? The Rumble 100's built-in overdrive has your back. Get the optional footswitch for instant onstage convenience.

More than just a solid performance tool

The Rumble 100 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 12" speaker for serious punch

Fender loaded the Rumble 100 with a single 12" speaker - the perfect choice for making sure your bass punches through the mix.

Fender Rumble 100 Bass Combo Amp Features:
  • 100 watts for serious stage presence
  • Single 12" speaker delivers serious punch
  • Vintage vibe with modern features
  • Footswitchable overdrive for extra aggression (footswitch available separately)
What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

Note: While Certified Open Box items from Fender do not include the Fender Musical Instruments Corporation warranty, you can shop with confidence knowing that this item is backed and covered by Sweetwater’s 2-year Total Confidence Coverage™ warranty.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!

Select manufacturers may require that only the manufacturer’s products qualify towards the minimum purchase amount needed to be eligible for promotional financing. Otherwise, an invoice that meets the minimum purchase amount and contains at least one qualifying manufacturer product is eligible for promotional financing. No interest will be charged on promo purchase balance, and equal monthly payments are required on promo purchase until it is paid in full. The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases. New Accounts as of 07/31/2025: Purchase APR is 34.99%. Penalty APR is 39.99%. Min Interest Charge is $2. Existing cardholders: See your credit card agreement terms. Subject to credit approval.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
