I just sold my Fargen Retro Classic when I bought my Mark V:35. The Fargen is definitely the best sounding plexi I've ever heard. Basically it's a 25watt Marshall Plexi SuperBass w/ KT66 power tubes. I needed more versatility, so I bought the Mark V:35. I'm a classic rock/blues player, so I definitely didn't want to give up my plexi tones. After playing both amps side by side, I found that I could dial in a really convincing Plexi tone on the crunch channel. I used the EQ and tried to tweak it as close to the Fargen as I could. Although I couldn't replicate the tone exactly, I still came **** close. The Mesa came out closer to a SuperLead rather than a SuperBass, which is almost the same circuit, just a little brighter. The way I look at it, the Mark V:35 got me close enough to Marshall territory, plus the added versatility of the other modes(and solo boosts), that I felt I could part with my Fargen. Oh, I almost forgot to mention that if you dig an old school JTM-45, then you can put it on the "fat" channel, gain at 3 o'clock, and kick in the mid/gain boost. It absolutely nails a JTM-45 tone. I will say one thing though, el84's are never going to sound as thick as el34's, BUT you can raise the 80ht on the EQ and it will def fatten up the bottom end for you. I hope my post helps. Cheers🎸🎸
