A good blend between practice and pro.

Having played guitar for around 30 years, I started playing bass at Music & Arts to entertain myself while my son was taking violin lessons last year. I had enjoyed the sound of the Fender Rumble bass amps but when I finally splurged to buy a bass the 100W Rumble they had for a while had sold so I settled for an Acoustic. Despite its promising specs, design and features it never delivered tone that inspired regardless of settings (with my Fender Player Plus Active P-Bass). The Acoustic went back. After varied research and varied YouTube review videos I decided to splurge on the Mark Bass 58R based combo rather than the Black Series option with similar dimensions and 1x12" configuration. The quality of construction for stress-free portability should I travel to play with friends or ever gig with bass was a factor, the "clip" light helping protect the circuitry for the gain knob was a factor as was the simple fact that it sounds and feels good with settings in the middle of all the knobs and the tonal variation from vintage to modern sounds and four band eq were all valuable features. It's also reassuring to know if I ever need to plug into an extension cab for more volume in a band setting it's got plenty of wattage to make it work without having to upgrade to a different amp. Buy nice or buy twice, right?

Good enough

This is the version to get. This mk 5 version has the new 58R series amp and it sounds incredible. Very versatile. Usable tones for most genres. Good enough for practices at bedroom volumes. Definitely needs an extension cabinet for full band practices or small gigs.

    After 30 years of playing bass—on everything from small bar stages to big rooms—and owning or gigging with just about every major brand out there (Gallien-Krueger, Ampeg, Fender Rumble 500, plus countless stacks and combo rigs), I can say this without hesitation: The Markbass MINI CMD 121P V is one of the best combo bass amps I've ever owned or played. This amp is a real powerhouse. Don't let the single 12" speaker fool you—this thing delivers serious volume, punch, and clarity. After decades of hauling heavy stacks, this combo feels like cheating. It's light, compact, and easy to carry, yet loud enough for rehearsals, bar gigs, and even larger stages when paired with an extension cab or run through direct out. The build quality is rock-solid, and it inspires confidence the moment you plug in. The manager at GC was awesome with the purchase too!

    I play with an acoustic trio in small to medium venues. I used it yesterday at a medium size bar/restaurant situation and it passed with flying colors. Great tone, plenty of headroom left. It's replacing my venerable Fender BXR25 (power supply fail). CMD121 vs Rumble 40, no contest.

    Great for home use and band settings. Haven't played it live, but it has no issues keeping up with a heavy drummer and guitar in a metal type setting for rehearsals. It's also incredibly light and compact, making it easy to transport.

    At age 73 I sought to find the best amp for Big Band Bass for me. This has the small footprint (26.6 lbs), great Italian looks, massive headroom/TONE, and the best features. This latest version V has everything conveniently on top. Find a GC and audition this amp! Highly recommended.

    Both my Rumble 100 and R200 were inadequate in Big Bands. The R200 sounded fine but was too large/boomy for Seniors Musicians I play with. I splurged for the CMD 121pV. It's PERFECT! Exquisite Tone and Massive Headroom in a small/light combo. Cover it! Use the financing for discounts.
