So far I have a bad relay on the power tube/rectifier pcb silk-screened RYF/H. Does anyone have a version 2 schematic so I can check voltages and get this amp up and going for an upcoming gig this month? It's a 2013 LSC with 100/50/10 watt settings. Thanks! Ed

I can see from the version 1 schematic they some what altered the circuit compared to the Mark I reissue, and some of what they did can squash the signal a bit killing the transparency of the tone, as some loops can. I will be making some tweaks on my version 2 to try to remedy it to a...

Hello, I just bought a Lone Star Classic version 2, 2013 in excellent shape but when I plugged in and switched from Tweed to Full power the amp stared humming so I shut it down and checked the power tubes, the 2nd power tube in from the tube rectifier side phenolic key pin was broken off and the...

I like these pedals, they seem to get a pretty good Boogie tone at easier to manage volumes. More vintage sounding not the Fizzy metal tones but like Santana and the fusion guys from when the Mark I and the IIC+ was young :) https://www.youtube.com/watch?v=Avmoi4UCLm0 And this one is more of a...

I recently picked up a Studio preamp and cleaned it up, changed the filter caps, did some re-voicing to be much closer to the IIC+ preamp. You can get so close since the effects loop is different than the IIC+ and Mark series. I have to say it sounded good stock, but with these mods in place I...

Is JVK still around? tried to contact but can't seem to get a reply... I thought these transformers were hard to come by???

Thanks all who replied, I appreciate it! :^)

Hi, this might be a crazy question, but a friend brought his 84' Mark IIC+ over the other day to compare to the Mark V IIC+ mode and in all modes (except maybe the Clean channel) of the V, there was this mid hump, almost like a 1/2 cocked wah tone that does not go away with the V. We were using...

I like this one myself :) https://www.youtube.com/watch?v=Avmoi4UCLm0

Hi GSX777, Regarding the 1/2 cocked wah sounds from V2 and V3 on your Mark V, was it just bad 12ax7's or did Mesa have to fix it? I just picked up a 2013 V and I am experiencing that 1/2 cocked wah sound, it really takes away from the Classic Mark sound, can you tell me more about those fix's...

Mesa Mark V head in excellent condition signed by John Petrucci. How do I post pics here?

Does it have Simul-class?

I'm selling my Axe Fx Ultra that is in excellent condition, it has never left my smoke free studio, has the latest revision 11, still has the protective clear plastic protective plastic covering the display screen. I am selling it for $1450 or possible trade for Mark V head. SOLD!

I am thinking about selling or trading my Mark IV head for a Mark V head. Seems a lot of V users are not happy with the #3 channel, but the #1, #2 channels are pretty good. I think I would like those 2 channels for my style and occasionally use the #3 channel. My Lead channel on my IV is very...

I am very interested in the V's Clean and Mark I modes, I am not totally sure on the Lead channel yet, but maybe I can work with it. I love the Lead channel on my IVB. Any suggestions welcome! I don't know if anyone is interested in some kind of trade here, but I am putting it out there Thanks!

I am very interested in the V's Clean and Mark I modes, I am not totally sure on the Lead channel yet, but maybe I can work with it. I love the Lead channel on my IVB. I have some replacement caps for the DC filament supply that needs to be changed to 16 volt, the factory installed 10 volt and...

I have studied the schematics of the Mark IVA, IVB and V. There are of course some differences in the lead circuits. First as the Mark IVA Lead channel is more designed like the IIC+, the little snubber caps (they help take out harshness and smooth the tone and add compression and reduce hiss...

I really like the Bluesmaster Overdrive myself! It works great with other pedals too, you can stack pedals with it, it acts a lot like an amp! It can get Mesa Boogie Mark I, Fender, Marshall and Dumble tones, it's amazing! My Zendrive is cool too but is somewhat limited in comparison, but works...

Well I have not checked out the 10/50/100 model yet and am curious. I have played the Special, sounded good, and the Classic 50/100, but I would need to tweak a few things to get it where I want it, and I prefer a 1-12 speaker configuration for the most part or actually a head would be good. I...
