Mesa Boogie JPC2million

[mooncobra]

just came back from the Mesa Hollywood store. played the amp. sounded ok. nothing too special. very busy in the midrange (its a Mark series, I get it)
Salesperson was waffling hard on the loop issue, first he was like NO there is no problem. then he spilled the beans, yes there was a problem, and they are fixing it.
so there it is. Everyone who gave Superunknown shit about the loop can go fuck themselves. IT WAS/IS an issue and Mesa is responding by doing some fix for it.[

YIKES!!

 

[Tone Zone]

So let me get this straight...after taking trash about Mesa and bombarding a thread for days about an amp you'd never even played, let alone owned, you finally go to a store and play one for a bit, then immediately run back home to not post in the 6 page long thread which is still going, but start your own completely separate thread to rehash the same tired garbage from the other one?

That, my friends, is the very definition of being a troll on the Internet.

No one should be giving Superunknown a hard time about his decisions. That's his money, his choice, and at least he owned the amp and made an informed decision on what he wanted to do. Everyone else can mind their own business. However, starting ridiculous threads like this is as bad or worse than what you accused everyone else of doing in the other. I've never seen someone have such a weird obsession over an amp they've never owned, don't want to buy, and have only played once in a store.

Reza is indeed full of shit. Someone summed him up so well, I had to make it my sig.

There's some angry Mesa love in here, look out

 

[Steinmetzify]

Wow. Can't we all just get along? This one got weird fast...

 

[shredi knight]

What in the hell is a manual?

I think he is the assistant manager at the Mexican restaurant that's a couple doors down from the Mesa Hollywood store.

C'mon, be nice people!

life. not everyone gets along, and not everyone is going to like everyone else. it is what it is. thats why you can block people here and never worry about it.

Reza, I dig your playing. I dig the demos you do. I think you have a wealth of knowledge about amps that's extremely useful for forums like this. I think your band rocks hard. That being said, you really do come across as a major dick in a lot of your posts. I'll bet you're really cool in real life and not at all like the smart ass you can be here. I'm just saying man. It doesn't hurt to be nice. I bet it's an LA thing.

So for those of us that use rack gear, without spill delay, would this be an issue at all? Also, at gig levels, per the manual, if you have the controls balanced, would this be an issue? Is there anyone out there with the amp that has played it outside their bedroom to test?

 

[Candiria]

Here you go VC4Eve. Each volume was at 10 O'Clock. Like it or not, this loop issue was in the design. I don't know if you actually own the amp or not, but the excuses about reading the manual, etc. just don't hold water anymore. My JP2C may actually be coming back because I really love the amp. Gonna decide tonight. Hope this finally puts this issue to rest. Peace.

From going off what the manual says, the settings used here would indeed have the same issue. All the volumes are set at 10:00, but the two gain controls on the lead channels are nearly maxed. The FX send on the gain channels is basically at full, while the clean's is at less than half. Could you run the volume on the clean at 2:30-3:00 (or wherever it needs to be to balance out the send level) and use the clean channel's gain control to set the volume level?

It's too late. The truth has been confirmed by our saviour and lord of tone, Rezamatix. They don't need manuals or is it manuels? to figure out how shit works. They just go right to the source. Mesa Boogie Hollywood store.

So this is the only guy on the planet that tried switching channels with delay on and discovered that?

You would have thought mesa would have tried some pedals in the loop and switching channels to maybe see what happens?

I fucking laughed out loud when I watched the video.

 

[VC4Ever]

Looking at the "truth" video you can see he has channel 2 and 3 gains all the way up. Here's what the manual says about that.

NOTE:
Using the upper range of the GAIN control invites possible microphonic or other gain related issues to become more of a
possibility. Avoid setting all the Controls–GAIN and TONE–in their highest regions as the combination of all of them pushes both
circuit and tubes to the edge of their stable region. Applying the SHRED Mode can exacerbate these tendencies further and it is near
impossible to use all the Controls in their highest ranges with SHRED activated. Doing so will likely cause a high pitched squealing
or feedback that is easily remedied by reducing one or more controls, especially the GAIN and TREBLE.

And once again here is the info about the Master volume control:

Unlike many other MESA amplifiers where the Channel MASTER also acts as an EFFECTS SEND control, the JP-2C required a
different layout to ensure the authenticity of the MARK II-C+ circuit. Here Channel 1 uses that scheme (Channel MASTER doubling
as a SEND Level control), but the two high gain Channels (2 and 3) see the GAIN control doubling as the EFFECTS SEND control.
The reason for this has to do with the fact that it is really the LEAD DRIVE control on a MARK II-C+, which WAS responsible for the
SEND strength in a II-C+. Regardless, despite this difference in both origination of the signal and control placement, the Channels
balance out quite nicely and you should have no problem with signal levels at your processor(s).

I know right? I haven't heard anyone else talking about it.

 

[sleewell2]

I haven't set my gain all the way maxed since I was 14.

Should have bought a 5150 III......... Am I doing it right?

 

[vultures]

50 watt. It has to be a 5150 III 50 watt.

I cant believe this is still a debate! There are a few guys over @ the Boogie board who have also confirmed the loop is funky and have already confirmed with the guys at Mesa there is a fix coming. That bit about "integrity of the circuit" was more than likely pr talk till they decided what/how/when they are going to address it. None of the Boogies I own and have owned in the past have had loop issues like this..{but..but..the settings!! ). Why is it so many people are quick to bash other users and not the actual amp itself? This seems like its a common trend lately and that blows. I even mentioned in the other thread that Superunknown seemed pretty knowledgeable but if it was user error then he made a mistake. It seems it is a very real issue and a fix on the way. Way too many uptight people.....

The clean channel stays pretty clean on most of the gain knob's travel so you'd be able to get it fairly high (as a send level) and still have a clean tone. When i tried the amp I didn't see ever getting CH 2 and 3's gain above noon. Very saturated. On the V it's similar. CH3 is heavy enough for anything, especially MK IV mode with the gain knob at twelve or less. Maybe bumping MKII mode to 1/1:30. Now granted I like a "clear" defined heavy tone and and stop turning the dial once palm mutes have just enough "sauce"
