Mark Bass Reliability

When I bought my three Markbass combos, the general consensus among the non-experts I'm apparently destined to run with was that "these new Markbass combos sure pack a punch for their size and weight but I wish they weren't quite so yellow and gosh they're kinda pricey but they're a huge step up for a small combo amp especially compared to those boat-anchor Workingman's things so I'll pay it".
I had a 2nd Gen Workingman's 12 combo I bought in the mid 90s for around $300. I already had a much bigger, modular amp, but wanted a combo for those combo situations. I liked that (for the time) the WM12 was affordable, portable, and sounded great. It could barely hang in a moderately loud band situation-it did much better when the amp was nearby and pointed at the drummer and an extension Bass Monitor 12 hooked up and pointed at me. It also doubled as a cool acoustic guitar amp, which was another need of mine. Interestingly, the California Blonde came out a couple years later. SWR clearly took the WM12 platform and tweaked it for acoustic guitar.
When I discovered the CMD121P, it was a game changer. Compared to the WM12, it was considerably smaller, lighter and more powerful. It was also rather affordable, as my MB was $400 used about 12 years ago. Compared to the adjusted price of the WM12, it was a bargain! New, I think the MB was around $700 at the time. The orangey-yellow color scheme was not an issue. When loading out of a dark club, bright colored gear is a bonus.
The MB also sounded more 'flat,' which was great for using it as an acoustic amp. I didn't lose a single feature of the SWR (effects loop, DI out, extension speaker jack) so I happily sold it. The WM12 was a very reliable amp, but it did start sounding pretty tired after 16 years of use.

I take it your experience may have been different.

So. Thanks. If I'm ever in the mood to get to the nitty-gritty on the definition of "premium" or even where the threshold into "boutique" might be, I'll be sure to come back to the Markbass appreciation thread oddly titled "Markbass Reliability".
Understand that most MarkBass combos use the same amp as their LittleMark series, in this case LM4, so you're getting in essence the same amp performance as their separate head. No compromise. The only other high profile Co that offers the same is GK.

Just sent this letter to Italy directly to Marco...

Marco De Virgillis
MARKBASS SRL – Via Po, 52

Dear Marco,

I am a professional bass player who has been performing for 57 years. I graduated from the University of Miami in Jazz Performance and am a long time personal friend of MarkBass endorse Frank Gravis. I toured with Buddy Rich and BS&T and did studio work in NYC in the early 80’s until I moved to Boston and started a successful music software company (Dr.T’s Music Software) in the mid-80’s. I was one of the first hires at Harmonix Music Systems, the company that created the mega-hit game Guitar Hero. I moved to New Hampshire in 1997 and have been playing continuously throughout New England since then with a variety of groups including James Montgomery Blues Band, Diane Blue, Once An Outlaw as well as my own 6/7 piece jazz-funk band - to name a few.

I thought you should know about my experiences with two of your LM III bass amplifiers.

I bought my first one at least 12 years ago - soon after it became popular in the US. I used it for 3-4 years with various 210 and 110 cabinets in many situations and it was just fine. It sounded good and was powerful enough for all the stuff I was doing - rock, funk, pop, jazz…whatever. Then unexpectedly, at a restaurant jazz gig through my 110 it smoked a little and died. This was a guitar trio and the guitarist had no issues with their amp and there was no surges. Fortunately it was a very local gig and my wife was able to bring me a spare. I looked into getting it repaired, but as I remember the cost was something around $300 to replace the board so I didn’t bother. I bought a Genz Benz Streamliner 900 and have been uneventfully using it for many years in all situations.

Recently I borrowed another LM III from my friend David Luke who makes the acclaimed hand-made RevSound speaker cabinets. His LM III appears to be around the same vintage as my original one. I used it at a gig filling in with a local rock band that plays all covers. They are not a loud band so I brought a new 112 cabinet. The amp and speaker combination sounded great and there were no issues at all. 5 days later i had a quartet jazz gig at a small venue where I play monthly. For this gig I brought the LM III and my 112 cabinet. This group features acoustic piano, bass, drums and tenor sax. I am the only amplified instrument. I plugged into the wall where I always do, plugged the speaker cable into the amp, turned on the amp, plugged in my bass and tested it to make sure it worked and that it sounded as expected. I turned down the volume, unplugged my bass, left the amp turned on and went into the green room for a soda and some pizza. Less than 15 minutes later a waitress came running into the room telling me that “your amp is on fire!” I ran in and indeed it was pouring dark color acrid smoke, but fortunately there were no flames! Needless to say I immediately turned it off and unplugged it from the wall. It was still in its carrying bag, but of course the front and back covers were open and the side vent holes were unencumbered as always. No one had been on the stage and there was nothing spilled on it.

Needless to say this was VERY disturbing as I never carry a spare amplifier. In fact, other than in the days when I toured, I have never brought a spare rig. And other than these two LM III’s I have never needed one. That covers Fender, Peavy, Walter Woods, Behringer, Genz Benz and Genzler amps for over 57 years!

I had been considering picking up one of the newer small & light Lttle Mark 58r 500w heads to use as a practice amp and for some of my jazz gigs, but this will most certainly not be the case. I’m sending you this so you understand how I, as a long-time professional musician, feel about the quality of your gear. And obviously I do NOT feel good…

Best of luck - sincerely,
 
Same here. My LMIII 10th Anniversary (Chrome front) was made in Italy and it’s been very dependable driving two Markbass 604’s for a good long time.
I had that same head and it was great! I wish I still had it but I was gassing for something else at the time . It never gave me any trouble and I had it working a lot. I don't know if I was just really lucky or some of the others on this thread were just really unlucky. I can understand the frustration though. I knew a guy who played a lotta golf and told me what a money pit that was. I told him if he ever got into music ... play harmonica.

Not sure the place of manufacture has much to do with the reliability to be honest. I did have a LMII which was made in Italy, and it performed fine for a few years until the power board went bad and the volume started changing randomly without warning. Wasn’t economical to repair.
That being said, it lasted longer than the Walkabout which replaced it! About 6 months in it released the smoke of death as the transformer melted.

My LMII is early-Indoneasian, and suffers from the (common-enough-to-be well-reported on TB) problem of on-delay at startup that deteriorates eventually into "won't come on at all". It is one of three Markbass combos I own, the other two being Italian-manufacture. I agree however, that country of origin shows little pattern when it comes to Markbass reliability/repair problems.

My disappointment with this thread is that it's 80% clogged with unhelpful, even disparaging comments from Markbass owners and defenders counting-coup with their own version of "oh well" observations directed at the ones of us looking for solutions, useful suggestions, patterns, alternate or outside-the-box fixes, since Markbass offers little information and charges bench fees to too-often tell their "customers" that the parts just aren't available with ETA unknown if ever.

I think that is the issue. Markbass uses parts and boards that are somewhat not able to be hot rodded or modded unless you are a top-tier tech with the ability to wrap their mind around the out of the box fix. Plus, it's not a huge company, with lots of tech support and service centers. I looked up their fairly short service center list and started emailing and calling to get my LMII worked on. It wasn't until the 4th contact did I finally get the OK to send it in, as the first 3 wouldn't or couldn't do the work.
In addition, the parts and such needed to fix these amps were more plentiful 4 years ago. It took months for them to just get the part/board needed. I'd wager they would have had that board on hand in 2019. I love my amp, but will say this experience of having it go down under less than average use with no abuse and then enduring a long, expensive fix did change my perspective on the company.

Thank you @SJan3 ...Markbass currently sells a Little Mark IV and a Little Mark IV 300. 500w and 300w respectively. Which would be a proper swap-in replacement for my original Combo II head? (My dead one switches on, fan runs, all lights work including the clip light, no sound, checked the head into another speaker, checked a different head into the 121P speaker, speaker's fine. Problem came on incrementally from slow-on to no-on). I guess I'm asking if my old Combo II head would have been considered "300 watts" or "500 watts". This amp would be returned to service as a "grab-n-go" for jams. I do not intend to drive an aux cabinet with it. Thanks!

If your CMD121P combo has a B&C speaker inside it'd definitely be worth repairing the amp or selling as is for someone to install a working head. How long since you bought it?

Manufacture date April 2014. Early Indonesian. How do I identify a B&C speaker? Tks!

Just Google it! Yours is a Marbass Yellow Line. Not sure whether B&C are involved with those but the cast frame B&C drivers were higher quality IMO.
