SERIOUS G.A.S this month.
« on: Time Format »

picked up an early jcm 800 canadian model. i wish i knew what year it was. man, this thing is louder than any other 100 watter i have ever owned. my only complaint is, its got no 16 ohm switch. stupid canadian laws.  :canadian-flag-banana-smiley-e  the matching 8 ohm 4x12 is at the store.

did i say this thing is loud?

and also a nice jcm 900 MKIII combo.

picked up a 1 watt jcm 800, then someone traded in a 100 watt a few days later. so i returned it back to the store, huge difference.






goodbye

i got myself a 1984.

i love it when amps are older than me.

Hey Marshall JMP, need your help

i want to re amp this head into my JCM 900 50 watter.

I have a rockcrusher that i can use as a load box. since the jcm 800 has no fx loop, anyway i can just only the pre amp on the jcm 800?

i am thinking about the matching cab. i am going to double check if hey are g12-65's.

do you have any experiences with them? how to they compare to vintage 30's? i am not a fan of the g12-75s coz they sound too scooped.

Go Chamai, nice acquisitions :thumb-up: , So what's the deal with not being able to have a 16ohm tap ?  :dunno: That's got to be one of the strangest things I ever heard.  I wonder if there is still a 16om tap on the output tranny ? (probably)
I know what you mean about loud, without a power soak my 72 50w seems to exceed local strategic armament regulations LoL Have to operate it by remote control from space (like Disaster Area (Hitch Hikers Guide, book 3-  Restaurant at the End of the Universe)  >:D .

some stupid canadian law back then. damn hard to find an 8ohm marshall cab. i need it because my attenuator only has 8 and 16 ohm. from what ive read, there is no 16 ohm tap on the tranny. i cant play this amp without an attenuator. it's just insanely loud. my jcm 900 is a joke compared to it in terms of volume.

Yep ,they were worried that the cable would catch fire or something like that because on the 16 ohm tap the voltage would exceed 40V and that's why there's no 16 ohm tap on it.And there also more fuses inside these Canadian heads.

So you want to hookup the load to the jcm800 and then take the attentuated signal and feed that into the jcm900 poweramp section ?I would not go to the front input, it will alter the sound too much.
The 800's,you have to set them loud to get both the preamp and power amp distortion.They don't sound so good at low volumes unless you put a boost in front of it like a TS-9 or an SD-1.

I also have a JCM800 from 81 (so first production year) and I also have the original cab for it with the G12 65 speakers in it.The 65 sounds like the V30 but it doesn't have the highs of the V30.So it's actually a warmer sounding V30 IMO.

gonna prob try to line out of my attenuator into the jcm 900 fx loop return and run a 16ohm cab that way.

the matching cab at the store came with g12t75;s. so i am gonna pass on that.

few things i can do.

use my jcm 900 as a slave.
buy a weber z matcher  (cheapest route)
buy another orange 2x12 so i can run 8ohms. rockcrusher has 2 speaker outputs  :whoohoo!:
find an old marshall cab with g12t65. saw 2 for sale locally a few months ago.

i am dying to try out the 65 speaker though. i like the bite and attack on the v30s, but the jcm 800 has a lot highs.

for now, i am stuck using my mesa recto cab.

yea man. i was so happy to find a near mint jcm 800.

man, i want a matching cab.

i think g12t75 speakers work pretty well with this amp.

i wish i had the extra $$$$$$ for the matching cab..

hell yea. paid $1250 canadian for it.

a lot of money, but i had to. ive never seen one in this condition. the metal switches makes it even better.

not much love the jcm 900 series for some reason. i think they are amazing.

i kinda miss my dual reverb.

I'm not sure why, I guess it could be that since the 800's are such a legendary amp the 900's didn't stack up. I've never played a 900 so I can't vouch for it's tone.

The JCM800 serie was the last best amp line that Marshall made, since then it's going downhill.

I know a LOT of people swear by the Jubilee Series, some akin it to a hodtrodded 800. But like the 900, I've not played one myself.
