The endowment effect - that's actually very true. Funny thing is that I am a finance professor and should know this!
I think you are right though - I need to sell them. I have limited time to play and when I do I want to go straight to an amph that has great tone right away. As a result I never touch those other amps.
I'll look into your recommendations.
Cheers
