JP2C in great shape, comes with foot switch and manual. $1900 and free shipping. This is a later model with a serial starting in 0008 (message me for full serial) and so it has the loop update. Thanks.
I'll have to check on the year, a few folks have asked. I'll get the serial and e-mail Mesa.
As for the loop/volume issues, I'm not sure what those are but I haven't noticed much difference using the loop or not using it. The amp sounds great either way and I have played quite a bit with and without.
Bump and update. This has the loop update as it is a later model with the serial starting in 0008. (If you want the full serial message me) Per Mesa the loop updates started at 425.
