 Posted: Thu Mar 30, 2006 4:21 am Post subject: CMI G80 |
 |
|
So, today this awesome biker hessian neighbor of mine came by and gave me a huge cab with 1 15" speaker and 1 12" speaker - on the front pannel it says it is a Harmony 570....and I cant find anything out about it.
He also gave me a CMI combo/head, model G80. I say combo/head because the thing is shaped like a giant head, but it originally housed 2 10" speakers. It was modified however, and the 10's were replaced with cheap 8" speakers - no biggie, I dont mind finding some new speakers to put in there and I plan to eventually put an output to connect to another cabinet anyway. The amp is 120 watts, and features two independent channels, one normal and one for reverb. Both channels have hi and lo inputs, volume, treble, and bass controls; the reverb channel has additional reverb volume, speed, and intensity controls.
This thing is a big heavy sucker and plays really well. I dont usually go for such a clean sound but the reverb sounds awesome and you can control the feedback really well, which sings and roars.
Sorry I dont have any pictures - I definitely will post some as soon as I can. If anyone could give me some information about this thing though, I would really appreciate it! |

A few months back I grabbed a mystery "Marshall" amp on ebay.de. The price was great so I figured I'd buy first and ask questions later.
Turns out it was a CMI PA with some mods that had been done to it over the years to make it look "more" Marshall-esque. Sounds great, and now that I've actually started to get a grip on its original appearance, I'm going to set about restoring it to as close to stock as possible (and reasonable).
And here's the catalog scan of the unit:

Mjet, that's a really interesting post. It looks like a CMI lead/bass 100W power section with a preamp similar to the Marshall Master PA. It also looks like a quad of Mullard xf4 power tubes there; in very good health. That's a very fine score and I'd be interested in hearing what the preamp section is like. IME, if the power valves are Mullards then the pretubes usually are, too.
If there are 6 ECC83s altogether, my guess would be that each channel has its own pretube for gain and eq, another '83 for mixing and one more for the phase inverter. Any more info you post up would be very interesting. |

Thanks for the quick reply, 1bassleft. I was very pleased to find some serious info about CMI gear - your post (linked via Google) was about the only sign that they ever existed!
I have done shamefully little with the PA since receiving it, but as I now know more about it I think I'll do some rehab work on it. To start with, I'll have the thin carpet covering stripped and put some Marshall-esque tolex on it. The knobs look to be original but the faceplate was stripped and cheesy stencils done on the indicator knobs. I suspect the Marshall logo was just pasted there because the previous owner figured that Marshall looked cooler than CMI. I think that I might be able to get a repro logo stenciled or screen-printed on (with new numbers too) although that might take me a while. I would very much like to get this thing into as close to original condition as possible.
Once I take it in to my amp-builder buddy's shop I'll take more detailed photos of the tubes and general set-up. I'll do another posting once that's done. |

I’ve just found this forum whilst trying to find some info on CMI guitars, which until this site I hadn’t found much at all.
I’ve got a CMI Gibson ES copy which I’ve had since the mid eighties and which I’m fairly sure the person who I got it off had had since the mid to late seventies.
I’m sorry I haven’t got a picture but it has the CMI logo with the lower case c upper case M and lower case I with a star instead of an dot. The logo is in silver text and until I read this forum I had no idea what it stood for, I’m still not sure from what I’ve read as to if it’s a Cleartone or Chicago (CMI)?
The guitar has a great sound with great sustain. It hasn’t got a bolt on neck or anything like that and it has a brass nut unlike some of the Gibson ES copy’s I’ve seen, as well as having a proper Gibson style tailpiece with a diamond design which I’ve never seen before. The diamond design is also featured in the dark blue velvet lining of the hard case, which it came in. All in all it’s a beautiful guitar, really well made with a great dark red finish. |

I have a 2x12 cmi 50 watt amp, but am not sure how to post pics here. It is built on a park tremelo chassis and has mid 70's rola greenbacks in it.
if someone can tell me how to upload pics I would be happy to.
thanks[/img] |
