Ok here I bow thy head in shame. The JP-2C is fine.

Title of the thread should be Tube amps, an emotional rollercoaster lol

Seriously I almost shed a tear when it started working right.

 

[godgrinder]

I am guessing one of the Mesa pres was bad to begin with but so was one of the replacements I put it.

Just make sure these go straight to the bin since they could come back and haunt you later when you forgot all about it, it happens.

Glad you got her figured man Its easy to get fired up, emotional, etc; I do the same damn thing and I was a repair guy/mechanic most my life But you always gotta step back and evaluate the problem and trouble shoot starting with the basics.

 

[mrhiwatt]

Glad it was simple. Let us know how you like it after playing loud and proud.

Great news!

 

[Whowantsamustache]

Cool. Like I said before it’s a good investment to get a tube tester like the one from Orange. You don’t use it much but it can save you from making a rash decision.

Final update.

I tested one last time before packing up the amp to send back and posted a video. The hommie Dave said I have a bad pre amp tube.

I literally just replaced them all with brand new tubes after noticing an issue to rule that out as an issue. I figured whatever, I have to put the Mesa tubes back in anyway so sure let’s check it out.

Literally the first tube I swapped was the bad one. So stoked right now. Full gain, full volume. Noob of the year.

That’s all I got. The Amp kills

this is the reason why I have an Orange valve tester....
Eliminating variables helps tremendously.

Tube tester now on the future list.

The amp is really awesome. The cleans are great. Probably the best cleans I’ve played on a high gain amp next to the Rockerverb. It can get super brutal and it can do Metallica all day. I’m now convinced Mesa did most of the writing for Metallica.

The crunch is ok. I guess that would be the weak spot. It is not horrible but it is no plexi that is for sure.

So glad I got it figured out. I knew I was missing some gain and it is not going anywhere. At least for a long time. Will try to record with the cab Clone soon.

Glad you got it sorted. I had a similar situation with some power tubes years ago. One blew and the replacement turned out to be bad. Was really confused about what was happening.

 

[napalmdeath]

I had a Marshall JVM about 6-7 years ago that was giving me fits. I tried everything, and was freaking out. I chilled out, and started going through everything a couple days in, and found the problem.. Battery going dead in my boost pedal.... DERP..

Shit happens, glad you got it sorted out. Nothing like finding a tone that's putting a smile on your face, and weird things happen!

Dude I’m glad you got this sorted! Now how bad is the crunch?

 

[xzyryabx]

To all tube sniffers, lesson learned I guess.
I'm always amazed at how good peoples ears are here....especially give the age demographic (oldish if you couldn't here that right!). Tthis tube rating vs another 1ma more, that transistor ohmage vs the one originally in the amp, flat wound strings, non-wound strings, chalambabamba > mahogany, these pups are wound X times more than those, doesn't have the "feel", whatever....all while playing blasting the volume too loud through high gain pickups that are likely too close to the strings, more amp gain than anybody needs, a million effects in the chain, commenting on iPhone video tone, all while having the clean pristine ears of a 500 year old dinosaur bedroom warrior....

Ya'll and wine snobs can all go fuck yourselves.
Just play/drink and STFU.

I feel sunshine blasting out my ass today, gonna be a good day.

Idk Jer, I need more time with the dials. I’m not much of an 80’s or crunch player. I guess I got a better VH than AC/DC but this amp just isn’t voiced for that I don’t think. Ch 2 and 3 are very close to each other. I think JP said they’re the same. I’m probably not the best person to dial in a crunch tone. I’m a metal player but compared to a Bray or an old Marshall or something the JP does fall pretty short.

It’s probably useable and I guess if it was in the hands of that type of player they could get a decent, useable tone but if someone was looking for a balls to the wall plexi I wouldn’t recommend the JP.

With all of the options I’m sure there are way more tones then I have gotten so far. I’d put more stock into someone other than me trying to dial in a crunch tone. Plus the amazing clean channel with the right pedal could probably do wonders.

 

[Riggins1966]

this is the kind of thing that makes me wish there were still tube testing stations at the corner drug store like in the 60s.

Glad you got it sorted out, now rock that mutha!!!!

I've always felt that Mesa amps in general don't do a great crunch. To me Mark's, especially at that gain level, are better for soloing than for rhythm playing. That's one area where the Mark V's are an improvement on the others, but I was able to get some decent crunch sounds out of my Mark IV, just had to use some strange settings to get it. IIRC I gunned the clean channel volume one day and that came out with a nice crunch tone, but I'm not sure you can do that on the JP because of how he wanted the clean channel.

 

[GJgo]

With my JP I could never get a good crunch. With my IVa it's difficult but possible on Rhy2.. With my IIs and III it's no problem.

Your issues are the reason why I went out and bought maxi matcher tube testers. I test every tube before it goes into any amp of mine. Plus, I know exactly what I’m using. I trust no tube venders.

Will look into this one and some others as well.

Need to test more. You can get breakup if you max the gain and play around. I will try but for me it’s all about the high gain brutal rythms. Do enjoy the clean channel though, sounds really nice.
