If I lost this amp, I would replace it with the same. I just don't know of anything else to compete with it. Don't get fooled by cheap amps with a big watt rating. MARSHALL RULES.
Use the modern setting for use with your electric guitar. (Remember how the Fender Bassman started out as a bass amp, but the guitar guys took it over?) Perhaps use the modern setting for slap bass, which is out of my venue. The Classic setting is good for more of an upright bass sound, especially with the Rogue Violin Bass with flatwound strings (an awesome bass!). I really appreciate the EQ flexibility, with the voice settings in addition to the bass - treble settings.
The quality appears to be very good. The sound is that clean Marshall sound that made their company famous. My amp is several years old, and was made in Vietnam. If the new amps are made elsewhere, then that could perhaps affect quality. More recently the speaker sounded like it was cracked, and the sound was mediocre. My bass strings were several years old, and I should have changed them. Anyhow, I replaced the speaker with an Emminence P102 (not a PB102, which is inferior in my opinion). This is a 200 watt bass amp speaker that Emminence claims is a possible replacement for the stock MB30 speaker. I also bought a new Rogue violin bass, and put on new Fender stainless flatwound strings. Wow, I am impressed with the sound. The trouble is, I don't know if the problem was the strings or the speaker... but it sure sounds great now. If you have the money, you might want to upgrade to the P102 speaker. (Check out the frequency response chart on the Emminence website, and it will really blow your mind... Super low response for bass, good higher frequency response for electric guitar. Wow.) Logically, you can drive the thing as loud as you want with this upgrade, as the speaker is 8 ohms 200 watt rating, and the MB30 is 4 ohm 30 watt rating... giving you a lot of headroom. (You don't want to use a speaker with an ohm rating lower than your amplifier.) You should be happy with the stock speaker for some time, but if it ever fails to satisfy, the speaker upgrade is a good thing.
In the store, when I tried it out, this amp with a meager 30 watts beat out every other amp until I got up to the huge Hartke speaker. I was really blown away at the time. I never would have expected a 30 watt amp to beat out the 60 watt competition. I wasn't even going to try it out in the store, as I had previously used a 60 watt Fender Rumble amp that was so bad (both for low volume and tone) that I took it back to the store for a refund. I thought I would have to get at least a 100 watt amp. Wrong. This is the winner.

This is a good practice amp but it is a bad amp if you crank its past level 4. this is not good for a show and it crackles after you play with it for a month. i do not recommend this amp for anything at all. if you are going to get anything for this amount of money get a bass or a guitar.

Perfect design for its intended use

By SkipToMyGroove

from Detroit, MI

Comments about Marshall MB30 Bass Combo Amp:

So I picked this guy up in a rushed state of necessity. I Just sold my truck and picked up a little sports car that can get the job done with my gear, but it's quite a pain. Hauling around the usual gear includes a 1/2 size upright, a marcus miller j, and either my custom built 6x10 flip top combo, or the eden stack. I was late, I grabbed the upright, and hit one of the shops I used to teach at to talk to a trusted salesman. We walked over to about 50 amps, and he pointed at the little marshall and, in trusting his opinion, I said I'd take it. Showed up to practice expecting a headache fighting the little baby amp to get the job done, and much to my suprise, everything sounded good, even without pluging in the Fishman preamp. I half expected a thiner, more rock sound, but it was great. Perfect for this little practice session. I brought it home and got to exploring, and I loved everything that came out of it. Every setting sounded exactly how I wanted it to, for every style I could think of, on the stand up, and the J bass. Dont expect to play gigs with it just because of the power, but it definetly exceeded expectations. Can't beat it for the money.

Great amp, for what I paid!

By NikeHeadBassist

from Suburban New York

Comments about Marshall MB30 Bass Combo Amp:

I purchased an MB30 amp, used, for $55. It sounds great, and pretty clear, despite the poor-quality pickups on my MIM fender jazz bass. The classic/modern selector lets you choose between a modern sound with compression, or a classic sound with gain, which is great as I don't have my own distortion pedal. It plays well with my bass, as well as several guitars (I'm the only bassist in a family of 5, and 3 of the other 4 play guitar.)It has some cabinet rattle, but other than that, it's a great amp. If you need a good bass amp, and 30 watts is enough for you (which it is, unless you're using it on stage at a noisy, crowded gig), then consider the marshall MB30.

THIS IS AN EXCELLENT AMP

By KenW in Portland, OR

Comments about Marshall MB30 Bass Combo Amp:

An evaluation of the Marshall MB30 bass amp, by a home recording engineer and beginning bassist, whose use is primarily recording of Christian worship music: My following evaluation was made using a Rogue violin bass (first version) strung with Fender stainless flatwound strings. This bass is noted for having ?hot? passive pickups and rich tone. To set a ?gold standard? for tone, I first tried a Hartke 360 watt amp with four 10? speakers (at 3 1/2 times the price of this Marshall). The tone was phenomenal, at neutral EQ settings. I then tried an Ibanez 60 watt amp, which gave poor sound quality, though more expensive than the Marshall. A Peavey Max 115 gave better sound than the Ibanez, but still had to be cranked up a bit to get sound volume, was higher priced, and too big to use as a practice amp in my home (and too big to reasonably transport to a gig). A Fender Rumble 60 gave terrible fret noise when set at neutral EQ, was too big to lug around, and more costly. (This Fender was one of the worst of all the amps I tried.) I then tested the Marshall MB30, and was AMAZED. The sound quality was phenomenal? to my ear, it was close to that of the Hartke. The volume was more than needed as a practice amp, and I never dared go louder than 3 or 4 on the knob (10 being the loudest). Once I had the unit home, I had to have the volume knob just under ?1? in order to keep the volume at a level that wouldn?t bother others in the house (this thing is LOUD!). I wonder if, with hot pickups such as mine, one could blow the speaker if the volume was cranked up all the way... It really cranks out the sound! I am impressed with the compression, which helps keep the sound tame when playing in a smaller group, and the line out, which is good for my work in recording, should I desire to record through the amp. The background noise level in the amp is impressively low, which is very desirable. It appears that the amp can give distortion, if one so desires, with manual adjustment of the gain and volume; however, as a sound purist, I leave it on the ?Modern? setting, which gives rich, deep tone. The weight is about ideal, at around 36 pounds. Less than that, the speaker cabinet would not have the mass necessary to give good tone from the speaker; more than that, and it would become too cumbersome to transport. As to looks, it is attractive. I like the external cabinet material, which appears to be some kind of plastic covering, which simulates coarse black leather. Conclusion: This amp is the best ?home sized? amp I have found on the market, and surpasses all others I have tried, for tone and volume, until one gets into the expensive high-performance gear. The 30 watts of power outperforms all 60 watt amps I have ever used. I assume that being new on the market, and with the electronic engineering done in the UK, it is probably state of the art in its use of wattage. I expect it to out-sell other amps once it gets discovered by the public. I recommend this amp to all bass players for use as a practice amp and for smaller gigs. If you need more horsepower than this, wait until Marshall soon comes out with the higher wattage versions in this line (check their web site for details). THIS AMP IS AWESOME. Postscript: Use quality cables with any instrument or amp. I am using the CoreX2 cable, which gives better sound volume and quality than my cheap cable performs with.

save up for an ampeg

By GodofThunderbird487

from Palmyra, PA

Comments about Marshall MB30 Bass Combo Amp:

I bought this amp because it was a marshall and it sounded so loud and crisp in the store. Well as soon I brought it home it was still loud even on 3 but I took it to my jazz band the next day and had the thing on 7 and the thing was barely loud enough. But at that level the tone was so crappy it was just pointless. THe classic channel is worthless is sounds like crap if u play with your fingers. Puts my Thunderbird to shame. Decent amp for a beginner but nobody else. If you have been playing long enough just skip it and buy an ampeg.

best SS bass combo ever

By woahwoahyeah

from wisconsin

See all my reviews

Comments about Marshall MB30 Bass Combo Amp:

Tons of tone options to play with. With the gain up it really growls (using a Squire J-Bass). Compressor on clean ("modern") channel is VERY useful when playing loud. With the volume on 10 it is just the right volume to go with an acoustic-electric guitar that is through a PA, though I highly doubt it could compete with a drum set. The line out is 1/4, not XLR, so that's another thing that could lower its live potential. Like I said, it's loud enough on its own (i.e. not line-out) with an acoustic-electric guitarthrough a PA, but not much more. Excellent tone. Highly recommend it as a first bass amp or practice amp for anyone.

It's a Marshall...a baby Marshall

By Skeeter G.

Comments about Marshall MB30 Bass Combo Amp:

This amp is just what I was looking for...a good quality small amp for practice. It is compact and not too heavy. The quality of construction is just what you expect from Marshall. It will do a fine job as a practice amp but you really wouldn't expect a small amp like this to carry a room with a couple hundred people in it would you?The amp has good tight sound and provides plenty enough bottom to deliver a satisfying practice experience. No, it's not one of the big boys but it'll do an excellent job when used as it was designed to be used.

Marshall bass amp

By Anonymous

from Undisclosed

Comments about Marshall MB30 Bass Combo Amp:

Absolutely incredible value! I just recently got hooked on bass after almost 10 years of playing guitar, and I'm playing a Fender Jazz with active pickups through this amp. The tonal possibilities are almost unlimited with the two channels and voice controls. Great sounds for jazz, slap, classic rock, blues, even heavier rock. The compressor is effective but kills a bit of volume some of the time. Other than that, I can't imagine a better value for this price range. The modern channel is addictive, and the classic channel will get you any rock sound you want. You'll spend days exploring with the voice control switch.

Perfect for my needs

By TeleCat

Comments about Marshall MB30 Bass Combo Amp:

I've played guitar for about 20 years and have recently decided to take up bass playing for a change of pace. After shopping around, comparing prices and features, I settled on this as my "beginner" bass amp. This was the only one that matched my needs for a fairly simple amp with at least a 10" speaker, no unnecessary FX or frills, that I can use for jamming when I build up my bass chops. The Voice Shift control is great for quickly changing the overall sound of the amp, and is one of the reasons I chose this over the MB15.Sounds very good cranked up, with no buzzing. It's somewhat heavy (around 30 lbs.), but I don't plan on toting it very far. It feels solidly built, and the exterior looks as if it can easily take some road abuse.Overall, I'm very happy with this amp.

Good sound, little over priced for features

By Benzotron9

from Salem, Oregon

See all my reviews

Comments about Marshall MB30 Bass Combo Amp:

This is a solid and powerfull amp. Nice tone. The only down side was that the excess features didn't follow through. Three settings with the amp itself are great! The others were not what I desired. Ibanez has a 35 practice bass amp that is equal and more fairly priced. If this amp was $30 cheaper it would be a good deal, but it is not a rip off either. I will only sell it to get a Fender Rumble, until then or if I get the Fender Rumble without having to sell my MB30 I will keep it. It is better than most but a little to pricy. You will get three good tones from the amp alone. A good effects box or foot pedal combo will make that meaningless and the MB30 can rock a house real well. Over all I am happy, but I would reccomend the Ibazez 35 watt bass amp. It cuts to the chase and is more affordable. I use an ESP ltd bass that is a beginners guitar so that might be my issue instead of the amp, but when I have used other amps their accessories worked out better I.E 7-10, instead of 3-10. But in Marshall's defense they are an electric guitar brand and a great one. Nice day

    I'm new to bass playing, and my bass is kind of low quality. But I can hear excessive noise when the treble or mid is turned up. I turned it up on accident, and could hear AM radio. This doesn't subtract too much value, as it still sounds good and is a starter bass amp.
