Thanks to everyone for the supportive posts. But no worries, I'm genuinely selling this package because I don't need the guitar any more and I have other amps & VPs.
I really got into C6th on that guitar but the 11 string Sierra gives me the top G
and D, so now I can let the Mullen go to a new home. The timing never occurred to me, I just put it up once I made the decision. If it doesn't sell now, next summer will be fine, I'm not in a hurry.

PS - just realised, once it's gone I'll have to change my avatar!
