Others have advised it already, but I'll second and third it - don't sell something you love. If you had iffy feelings for it, OK, but if it's something you know that you will ultimately miss, don't sell it. I still regret selling my 80's BC Rich USA Gunslinger Custom oh so many years ago because I needed the money for another purchase. I could have saved the money in a few months and bought what I bought with the money from that guitar instead of selling it, but the bright shinning new item fucked with my judgment and I miss her (my guitar) to this day some 20 years later.
Save for a few months or whatever to buy another Mesa cab, just don't trade something you know you will miss.
