BlackBoxy said:very surprised Mesa present it as a MArkIIc , tones seems closer to the V on the video..
why buying a dearer MARK 5 ? don't get it
I can dial in my C+ to sound fairly close to the lead tone in demo video. However thats not the tone I use, I set it to sound more Santana ish . My assumption is I should be able to get that tone from the JP 2C. But gpuma makes a great point . Would love to hear what other tones this amp is capable of . What if It won't replacate the tone I use like a vintage C+ . As its been pointed out in some of the threads about the JP 2C , This is JP'S idea of what a C+ should sound like. I guess the only reason I'm pondering this, I was going to order one Monday morning. Maybe I'm caught up in the hype but I also like the way this amp gives you the option of switching between the 3 channels which is much more live performance friendly. Maybe I'm just over thinking the whole thing. Guess I'll sleep on it and see how I feel about it in the morning. If I decide to go for it I don't want to wait forever for it to show up and I suspect Monday morning will be very busy at Mesa after the release of the demo video.gpuma said:I understand it is his signature amp, but I would like to hear more than an amp that just makes the JP tones.
I am sure that Petaluma will publish follow up videos exploring other areas, hopefully it will not take too long
It seems to me that mesa is only listening to JP with regards to this amp, not their costomers. it always seemed to me that mesa never wanted to reissue the 2c+. They bragged about how the circuitry was the same in the Mark v c+ mode. So for a while it looked to me like that was them putting their foot down saying, no reissue, this is just as good. But now they're using words like "even more legitimate" in describing this new JP model. What the heck does that mean? Does that mean it sounds more like a 2c+ than the V's? They promised the V's were the real deal c+ circuit, now it seems like theyre saying there's an even realer deal c+, that's actually legitimate, as if the V's are not. Sorry to sound negative on what is going to be an amazing amp but what's next mesa? A real reissue that's even more legitimate than this one?Nicklotsaguitars said:Sounds like my Mark V.
That is a lesson in how Mesa listen to their customers. That amp has all the things I've seen recently discussed on this board. 2 sets of sliders. For the preset vs sliders thread. 2 channels doing the same thing so you can get a very different lead sound to the chugga chugga sound. Big transformer...
It does sound phenomenal on that vid though. Gonna have to play one in person.
barryswanson said:Good point. The only thing Mesa said that was different on the V apparently is the coupling capacitor. But you do make a good point what else is different ? I wish some one would do a sticky on how to change that coupling cap from the none EQ to the EQ version on the V :mrgreen:
Bottom line - JP will sound like JP through a twin reverb/telecaster set up, you'll sound like you through the JP2C. I'd rather have JP's input than every Dick and Harry's input. I can not wait to get my fingers on one of these beast. The Mark25 was nothing like the Mark V or IV. The Mark25 can breathe fire and I expect the JP2C will have that ability. The twin GEQ's and simplicity of design along with that monster transformer, YMMVIt seems to me that mesa is only listening to JP with regards to this amp, not their costomers. it always seemed to me that mesa never wanted to reissue the 2c+.

On the Mark V:25, to my ears, it's a little higher, high is why the amp is such a fire breather compared to it's big brother (says me, anyway).
(I don't know what it is set to on the V:35)
Apparently, on the JP-2C, it ranges from 7.75ish to the high 9 range depending on the channel and whether or not the gain control is pulled. THIS IS AWESOME.
Hey there, of course I don't want to start another "pre-500" threat but if you do the math from the schematics, the big daddy V is set to 6.0 (pot ratio is at 60%). Even if the change to EHX pre tubes made this my absolute dream amp... the change is very easy to be done and if I open her up I will shurly try it out by setting the volume to 7.75
Would be interesting to know the value of the mini markv ... can someone please have a quick look?
Thanks in advance
Your maths are true but your linear scale assumption is wrong.APEMAN said:On the IIC+ mesa used a 1Meg pot, on the V they used 4 resistors R22 to R25. Two in a row forming a voltage divider with 386k and 570k (in sum 956k with a ratio of 386k/(386+570)k=0.5962) which makes 6.0 on a linear scale from 0 to 10.
