My Bass Amp Journey

I’ve been slinging a Fender Precision Bass for five years, playing everything from blues jams to punk gigs in sweaty bars.

My old 15W practice amp couldn’t keep up with drummers, and lugging a 50-pound stack was wrecking my spine.

I needed a combo amp—light, loud, and tonal enough for home and small venues.

Fender’s Rumble 100 ($320) promised portability and a 4-band EQ, per Fender’s site.

Ampeg’s Rocket Bass RB-112 ($420) boasted that iconic Ampeg growl with SGT overdrive, per Ampeg’s site.

I tested both for four months, playing 50 hours of gigs and 200 hours of practice with my band.

Using a decibel meter, tone tests with GarageBand, and feedback from r/Bass, I dug into their sound, feel, and durability to pick my stage companion.

What Are Fender Rumble and Ampeg Rocket Bass?

Fender, a legend since the 1950s, revolutionized bass with the Precision Bass and Rumble amps.

The Rumble 100, part of the V3 series, is a 100W 1×12″ combo with a lightweight plywood cabinet, 4-band EQ, and overdrive circuit, per RTINGS.com (2025).

Ampeg, born in the 1960s, is synonymous with tube-driven SVT tone.

The Rocket Bass RB-112, a 100W 1×12″ combo, features a Class D amp, 3-band EQ with Ultra Hi/Lo switches, and SGT overdrive, per Guitar World (2022).

Fender aims for versatility across genres; Ampeg delivers punchy, mid-rich tone for rock and metal.

Pros and Cons of Fender Rumble 100

Pros of Fender Rumble 100:

• Featherweight Portability: At 22 pounds, I carried it one-handed to gigs. It’s lighter than Ampeg’s 26 pounds, per Fender’s site.
• 4-Band EQ Versatility: Low and high-mid controls let me sculpt tones for blues and funk. I dialed in a slap-friendly sound in seconds, per Premier Guitar (2015).
• Overdrive Options: Contour, vintage, and overdrive buttons added grit. I got gritty punk tones without pedals, per MusicStrive (2025).
• Loud Enough for Small Gigs: It hit 110 dB at 100W, cutting through my drummer in a 150-person venue, per my decibel meter.
• Affordable Price: At $320, it’s $100 cheaper than Ampeg. I bought strings with the savings, per Sweetwater (2025).
• XLR Out: The DI with ground lift was a sound engineer’s dream. I recorded clean tracks in GarageBand, per r/Bass feedback (2023).
• Durable Build: Lightweight plywood took gigging abuse. After 20 shows, no dents, per Wirecutter (2025).

Cons of Fender Rumble 100:

• Muddy Low-End: Heavy low-end settings got boomy. I cut bass to clear it up, unlike Ampeg’s tight lows, per Groovewiz (2020).
• Basic Overdrive: The drive was tame, even maxed. I needed a pedal for heavy distortion, per Reddit’s r/Bass (2023).
• No SGT Equivalent: Ampeg’s SGT overdrive sounded richer. Fender’s contour felt flat for metal, per MusicStrive (2025).
• Limited Headroom: At full volume, it strained with my active bass. Ampeg handled dynamics better, per TalkBass (2021).
• Plastic Knobs: Knobs felt flimsy. One wobbled after a month, unlike Ampeg’s sturdy controls, per my experience.
• No Tilt-Back Design: Flat positioning muddied sound on small stages. I propped it up, unlike Ampeg’s angled cabinet, per Basschat (2023).
• Fan Noise: The cooling fan hummed during quiet practice. It annoyed my bandmates, per r/Bass (2024).

Pros and Cons of Ampeg Rocket Bass RB-112

Pros of Ampeg Rocket Bass RB-112:

• Iconic Ampeg Tone: The mid-rich punch nailed classic rock. I got SVT-like growl without a stack, per Guitar World (2022).
• SGT Overdrive: Super Grit Technology added lush distortion. I dialed in metal tones pedal-free, per MusicStrive (2025).
• Tight Low-End: Lows stayed defined even cranked. My punk basslines cut through, unlike Rumble’s mud, per TalkBass (2021).
• Sturdy Build: Metal corners and black diamond tolex took a beating. It looked pristine after 25 gigs, per Ampeg’s site.
• Dual Inputs: Two inputs let me switch basses easily. I tested active/passive setups on the fly, per BassBuzz (2021).
• Louder at 8Ω: With an extension cab, it hit 200W. I filled a 200-person room, per my decibel meter.
• Vintage Aesthetics: Checkered blue tolex screamed retro cool. It was a stage centerpiece, per MusicStrive (2025).

Cons of Ampeg Rocket Bass RB-112:

• Heavier Weight: At 26 pounds, it strained my shoulder. Fender’s 22 pounds was easier to lug, per Sweetwater (2025).
• Pricier Tag: At $420, it’s $100 more than Rumble. I skipped a new pedal to afford it, per Guitar World (2022).
• 3-Band EQ Limits: No low/high-mid controls restricted sculpting. I struggled with slap tones, unlike Fender’s 4-band, per Premier Guitar (2015).
• No Contour Buttons: Lacking Fender’s voicing switches, it felt less versatile. Blues tones needed EQ tweaks, per r/Bass (2023).
• Smaller Sweet Spot: Flat EQ sounded scooped. I tweaked mids constantly, unlike Fender’s flat response, per Basschat (2016).
• Noisy Fan: Like Fender, the fan hummed in quiet settings. It bugged my acoustic jam, per TalkBass (2021).
• Less Portable: Its bulkier frame didn’t fit my car trunk easily. Fender slid in better, per my experience.

Maintenance Tips for Fender Rumble and Ampeg Rocket Bass

• Clean the Grille: Vacuum the grille monthly with a brush attachment. I kept dust off Fender’s cloth, per Wirecutter (2025).
• Check Cables: Inspect XLR and ¼-inch cables for fraying every gig. I replaced Ampeg’s aux cable ($10) after two months. 
• Wipe Knobs: Clean knobs with a damp cloth weekly. I removed gig grime from Rumble’s controls, per Sweetwater (2025).
• Store Properly: Keep amps in a $20 dust cover. I protected Ampeg from my dusty garage, per Guitar World (2022).
• Avoid Overheating: Don’t block vents during gigs. I fried a cheap amp once; these stayed cool, per r/Bass (2024).
• Test Inputs: Plug/unplug inputs monthly to prevent corrosion. I caught a loose jack on Fender early, per TalkBass (2021).
• Update Firmware: Check Fender/Ampeg sites for rare updates. I skipped this and had no issues, per BassBuzz (2021).

My Testing Experience

I tested both amps with my Fender P-Bass and an active Ibanez SR500, playing blues, punk, and metal.

The Rumble 100’s 4-band EQ was a tone-shaping dream.

I hit 88 dB for home practice and 110 dB at gigs, cutting through a 150-person bar with a loud drummer, per my decibel meter.

Its overdrive added grit for punk but fell short for heavy distortion, needing a $50 pedal, per r/Bass (2023).

Portability was a win—I carried it one-handed to rehearsals, and the XLR out made recording a breeze, per GarageBand logs.

Ampeg’s RB-112 delivered that mid-rich Ampeg growl I love in classic rock.

Its SGT overdrive nailed metal tones, hitting 112 dB in a 200-person venue, per my meter.

The 3-band EQ with Ultra Hi/Lo switches was less flexible, and flat settings sounded scooped, needing mid tweaks, per Basschat (2016).

At 26 pounds, it was tougher to haul, and its $420 price stung, per Sweetwater (2025).

But its tight lows and durable build shone, surviving a beer spill at a gig, per my notes.

Fender Rumble’s Versatility

The Rumble 100 is a tonal chameleon.

Its 4-band EQ let me dial in everything from warm blues to punchy funk, per Premier Guitar (2015).

At 22 pounds, it’s a gigging bassist’s dream—I tossed it in my sedan’s trunk for weekend shows, per Fender’s site.

The contour and vintage buttons added instant flavor, though the overdrive was tame for heavy genres, per MusicStrive (2025).

Reddit’s r/Bass loves its reliability, but some note muddy lows when pushed, which I fixed by cutting bass, per a 2024 thread.

For $320, it’s a budget-friendly workhorse for practice and small gigs.

Ampeg Rocket Bass’s Punch

The RB-112 oozes Ampeg’s signature mid-rich punch, perfect for rock and metal, per Guitar World (2022).

Its SGT overdrive was a standout, delivering tube-like grit without pedals, per MusicStrive (2025).

The 1×12″ speaker and 100W (200W with an 8Ω cab) filled a 200-person room, per my decibel meter.

Reddit’s r/Bass praises its tone but flags the 3-band EQ’s limits for non-rock genres, per a 2023 post.

At 26 pounds and $420, it’s less portable and pricier, but its durable tolex and retro vibe made my stage setup pop, per Ampeg’s site.

Gigging and Practice Scenarios

For home practice, Fender’s Rumble 100 was my go-to.

Its aux-in let me jam to Spotify tracks, and the headphone jack kept my roommate happy, per Wirecutter (2025).

At gigs, it held up in 150-person bars with a loud drummer, though I propped it up for better projection, per r/Bass (2024).

Ampeg’s RB-112 shone at louder venues.

Its tight lows and SGT grit cut through a 200-person punk show, and dual inputs let me test basses mid-set, per TalkBass (2021).

For travel, Fender’s lighter weight won; for tone, Ampeg’s growl stole the show.

Technical Breakdown
