Mesa Boogie MK III – one of the baddest amps ever made?

I bought one of these beasts in 1990. I said to the guy in the guitar shop in Twickenham – what’s the best amp you have in the store? (of course I now know that was a bit of a silly question but I was 21 so what did I know?!). He looked around and said – this Mesa Boogie Mark III is the most expensive. I wasn’t after it because I wanted the best amp in the world – or wanted a better amp than my friends – I just don’t like worrying about what-if – or perhaps I should have bought – or oh drat – it doesn’t do such and such sound. The shop owner said this would do almost everything sound-that other amps did – because it was modelled on their circuitry + it did a bunch of it’s own sounds – now I think generally referred to as the ‘Cali’ sound. Great I thought.

The Mesa Boogie MK III like all Mesa’s is beautifully put together by hand

Anyway – I bought it (when I had a reasonable day job and a steady income I hasten to add) and really didn’t do much with it for 30 years. It was wasted in me I found out later as I never had a chance to play – always tied up with that annoying need of having to food in my mouth. Actually – I thought it was a rather dull sounding amp. But that’s because I used to round off the top-end as I had an eversion to whiny screeching trebly 60’s sounding guitars that hurt my ears + 1 guy in the band I was in insisted on burning out my and everyone else in the band’s ear drums every time we practiced. But I was a bit disappointed – the amp sounded nothing like my hero James Burton or Jimi Hendrix – it just sounded non-descript – so I assumed he told me a load of baloney.

Well anyway – a few years ago I started researching amps as you do online – because everything is there now isn’t it? Basically I needed to re-valve the thing as the reverb was not working and there was now almost zero overdrive coming out of the thing. I started to watch shootouts of all these amps and couldn’t believe it – apart from I think a Soldano which seemed to top it a bit on ‘nastiness’ with high-gain – this old black box was sounding better to my ears than all the other amps it was pitted against – and quite a few of the testers themselves came to the same conclusion.

Trying to figure out why the reverb stopped working (I don’t much like spring reverbs but whatever) this was the first time I looked inside this Mesa Boogie MK III beast of a guitar amp in 30 years. Rather beautiful to look and nicely made. Hope you enjoy looking in there as much as I did! Remember – these things kick out death-inducing amounts of electricity so be VERY careful poking around in your guitar amp electronics. I was literally shouted at by a local guitar amp tech when I told him I was poking about in mine!

And then something else happened – I started playing with the amp settings myself – properly – and… well I was really surprised. Not only did I find that the bit in the owner’s manual about it only needing a nudge here or there on a dial to completely change tone was true (in conjunction with nudges on other dials which I never ever did) – I found the sound was beautiful – it shimmered to use that over-used term!

Then I read about different valves and whilst I don’t think they play a huge role – switching these in conjunction with speaker jacks I got some really nice sounds I never knew were inside this box. Silly me – only 30 years to find out! But that’s what happens when you are bogged down in day-to-day work scratching a terrible living and worrying to death every day about everything but what you like doing or are good at.

Now I can say I’m so happy I bought this amp – not least because I could never afford another guitar amp like this – I have to say now – it is a beast – but in al the right ways!

One Mesa Boogie User says: I think the MkIII is the best amp that Boogie ever made, and I have owned most of them. Mike Bendinelli once told me it was due to the output transformer, which apparently was different from all their other amps.
