sheehanje,
I have gotten used to my Roadster that is basically the same tone with some variations on each channel. I will get slammed by the DR people for that.. It is more than just one theme or flavor to be honest but does not have the complexity of tone changes or character that the Mark V has. I would say the one trick pony I currently have would be the RA100, actually that amp is flexible too but has that vintage vibe I love so much. The half stack is awesome but the combo serves it up in a different character. Sure both amps sound identical though either of the 412 cabs. The RA100 seems to put a smile on my face more than the Mark V ever could (before I made a few changes). Roadster is just raw to the bone punch and I am still learning more about it. Finally did a detune by a half step down (D#,G#C#F#,A#,D#). Holy Hana did that really wake the amp up, I was running both 412 cabs when I did it. I normally play standard tune. Methinks I need a 7 or 8 string guitar now. I do like the Mark V and since I have had the love/hate relationship with it I probably would not miss it if I sold it.... or would I? Of course I would. From what I read thus far, the JP-2C can get close but not close enough to the CH2 Crunch. Just that voice alone driving two EV speakers with the gain maxed out is pure nirvana and seems to perform better than the Roadster in that regard. (trick is the preamp tubes in use, especially in V2).
I am not getting the JP-2C to replace the V or any other amp (I did consider selling off some gear to get it though but decided on a different plan instead).
I have had a gear fund account that I created just for that purpose. I have more of an issue saving money so if it gets automatically transferred on a schedule I can save up money as I will not spend unless needed. That helped me get some Strymon Pedals, a new guitar (usually the tax refund fuels that).
I have GAS but I have learned to be patient. Everytime I have sold something I end up getting a fraction of what I could have gotten.
Lesson well learned from my past mistakes. I had a Les Paul Spotlight that I bought new in 1984. Owned that guitar up until the end of 1999 and was forced to sell it to finance my divorce. I paid $890 in 1984 (list was $2,00). When I sold it I got back what I paid for it as I was in need I took the bath as not many places would offer me any more.
I was commenting on the exact same guitar and shared a picture of it that I still had. I decided to look up the specs as I could not remember what pickups were in it and found a Reverb listing that turned out to be my old guitar. Things like this happens when you sell gear even when you know there is more value than what you are getting in return. Here is a picture I took back in 1985 when I was in high school, had joined a photography club so black and white film was a requirement. The image is proof positive it was my old guitar in the Reverb listing.

I only wish I was the recipient of the $8,495.00. I got rooked and knew it when I sold the guitar in 2000 only to get $890. 00. That is how life is sometimes.
