JCM 100W 2210 into 2 v30's ....

spiritdave · 07-25-2012, 03:40 PM

My rhythm guitarist uses a 2x12 cab with v30 speakers and runs a 100 watt JCM 800 2210 into it ... he doesn't smash it to 10, but I know he pushes the master at 7 sometimes. Unsure about the rest of the volumes. Too loud all the time :P

Anyways ... his amp started making grainy tones the other day at rehearsal.

Could that be due to the load on the speakers being too much?

My 2210/2205's do/did not get louder after 4 on the Master Volume, it just adds negative artifacts. I would also advise to run the Boost Volume no higher than 9. This will keep the preamp tone non-brittle. In addition he should perhaps look at trying out a few different 12AX7's in the V1 spot. However it sounds as if he may be deaf and this may not apply. All ears are NOT created equal.

Good luck and keep us posted. That amp should sound great through V30's.

Believe me ... his amp gets a LOT louder from 4 - 7 I can assure you lol. FAR too loud. This only just started to occur last rehearsal ... I've never noticed it before. He's always had pretty good tone (it's MY cab and I sold him the Fender Telecaster he uses!)

But damn, it sounded crap the other day. Thanks!

Keep in mind that these amps have 3 Volume controls total when being used on the Boost channel. (1) Master (2) Boost Channel Volume (3) Boost Channel Gain. Check these settings for standard consistency. These controls are very interactive on this model, both pre and post 1986. I run mine Master 1-2 as needed. Boost Channel Volume 8-9 Boost Channel Gain 10. Then I hit it with a SD-1 at times. Ouch!!!

Having three volume controls on the boost channel really gives you a lot of power to shape the sound. Just one of the reasons it is such a great amp.

could just have had bad power or his tubes are going. CP tubes don't do well in vintage amps anyway let alone for any length of high volume use. i'd wager it's just simple tube wear.

yep .... check them tubes !

yikes 7+ on the master volume .... he likes to hear it !!! Ha !!!

Normally 120 watts of speakers would be fine with a 100 watt amp.

Perhaps what is sounding bad is cone cry which is fairly common with pushed to the limit V30's.

But then cone cry does not sound as you described "grainy".

That aside, V30's handle more wattage but just aren't built as robust as G12H or G12M speakers when driven hard.

Either get two more V30's and load up a 4x12 to lessen the load or change speakers to G12M65's (the new creambacks might work well) if he keeps the 2x12.

Keep in mind, when a tube amp is running that loud, with the power stage overdriven, it can put out almost twice its rated RMS wattage.

Vintage 30 speakers are rated as 70 WATT speakers = 280 watt load. They handle 100 watt heads just fine.

All the V30's I own are rated at 60 watts each.

My (year 1996) 1960BV Slash Cab is rated at 280 RMS. 70 Watt V30's.

Mine are Marshall Proprietary Vintage 30's designed for Marshall in 1986 by Celestion. Later Mesa wanted their own version and even later Celestion made a 3rd version for their self to sell to everyone else, Randall, Orange, Bogner etc...

All Marshall 1960V cabs I have seen are rated at 280. All Mesa V30 212 cabs I have seen are rated 120. Again different speakers. Mesa's seem to have even more low mids.

What DO Vintage 30's sound like? - The Gear Page

Thanks for the info

I would love to try out the different voicing in these speakers.

I'm getting that GAS again

Assuming the 2x12 cab is 8 ohms.
Hopefully your rhythm guitarist is not runnin 16 ohms from his amp head.

Blueslicks · 07-26-2012, 01:03 PM

The OP said the cab in question was a 2x12 with V30's.

V30's are rated 60 watts each.

2 x 60 watts = 120 watts.

Not if they are original Vintage 30's.
