JCM 2000 Noob question

[tonyp1]

I have a JCM 2000 Triple Super Lead 100 W Head that I have hooked up to MG 412 cab 120W.

I’m keeping this at bedroom volumes 2… Anyhow will it harm the super lead being paired to this 120W cab?

I’m not going crank it this would be just bedroom volume.

I understand the basics of a 100 W head paired to a 120W cab. But not in the context of a tube amp and understand the JCM 2000 is vastly over powered for the MG cab.

At maxed volume, the TSL could overpower the 120w MG cab, but you should be fine at bedroom volumes.
Some better speakers with higher power ratings would solve any issues, and probably sound way better.

Should be OK at low volume as @fitz said.

Congratulations on the new amp.

Welcome to the forum.

Thanks!

No issues playing a 100 watt amp into a 120 watt cab playing at low volumes, none at all. I’m not very familiar with MG cabs, what speakers are in it?

Even with the volume turned up a bit it would be safe if they’re Celestion speakers, even budget Celestions can safely handle, (within reason of course), more watts than they’re rated at.

Welcome to the forum. I'm not a real expert but I think the amp is rated at 100W and the cab at 120W, assuming the speakers are hooked in parallel. One would think this is perfectly ok. However, as the amp is turned up it starts to clip and that can send out higher than rated watts. Because the cab is so close to 100W, the idea of getting different, higher rated speakers is a good one. Or keeping the volume knob below 6 would probably be safe. My 2X12 cab has two 60W V-30 Celestion speakers so it could take 120W presumably. My highest watt amp is 50W so I feel I am safe, plus I don't push it in the house. I had a stereo many years ago that clipped my speaker and I had to get a new woofer for it. I had that amp cranked to the max in the dorm room. I don't go to 10 or 11 anymore.

Hopefully that helps.

No problem my friend. It works.
Don't let the talk bother you.
Bottom line is, Do you like it.

I have used several different heads with MG cabs.
I am very surprised how well they can sound.
I think the straight ones seem to have more thump and spew less high end at your face.
I have one now driving it with a Peavey valveking 100 watt tube head. LOUD AND PROUD THE BASS MOTE CAN SHAKE THE PLACE

 

[Mrmadd]

Some of them, I have upgreaded the drivers.
Mixed results, but usually a big improvement.

 

[Mrmadd]

For under $200 in GC used. Can't beat it.

For my next trick, one of them gets Greenbacks

 

[Mrmadd]

You can't self build cabs that cheap.

Good luck, enjoy!

 

[Mrmadd]

In your photo you show a cab stacked on your head.
Make sure you do not overheat the amp head, even if you play at zero volume.

I love my DSL 100s.
Keep good ventilation on those tubes at any volume.
Enjoy

 

[slade]

Definitely use the VPR on it, you’ll be able to raise the volume more which will help get the amp to breathe a little.

 

[LeftyGtrPlr]

I've been looking at the JCM 2000 TSL's. I love my JCM 2000 DSL 50, I just wish all 4 channels were foot-switchable. I feel like the TSL solves for that, so you can have a good lead channel set.

Didn't mean to hijack the thread. As others stated, you should be fine at lower volumes and you can always invest in new speakers for the MG cabinet.

You should be fine my friend, just do as you said an don’t push it.

I am also a user of MG cabs..
And I have changed out a few speakers in a couple of them..
But I still have a long way to go on putting quality speakers in them all.

My avatar pic as a couple of them under my Dsl40c’s.
Enjoy your rig bro

Bottom line is that guitar speakers ratings are for continuous power but you are playing musical power which means the cabinet can actually handle twice the power of your playing, 240 watts.

It would be more important to match up the OHMs

 

[Mrmadd]

If you want more bottom thump, a 1960 size cabinet is the deal. The MG cabs have lss cubic inch space and
the speakers are pressed in there tight. I put a 1x5x4 in port in one of the MG cabs and it helps.

Another theory you could try, replace 2 of the speakers in the cab with really good drivers. Say "creambacks"
Match up whateever ohm scheme you like. Use the 2 good speakers and let the other 2 speakers go not connected.
They will act as a passive port giving you a little more bottom thump.

Realize this, anytime you alter speaker cabs, you are re-engineering the response the cab will deliver.
Sometimes you win, sometimes it is a waiste of time.

Good luck
