MOTM

All,
  Playing MOTM through an amp.  I have a peavy KB60 12x1 amp its nice and 
loud etc..  I think the reverb is kinda shitty though..  Ive mesed with a 
2600's spring reverb and think it sounds much better.  Has anyone built Paias 
hotspring reverb?  Any comments on any nice sounding spring reverbs out 
there?  Ive also heard that a spring reverb shouldn't be solidly mounted but 
suspended so the feedback stays undercontrol.  This makes sense, has anyone 
played with this, ala old fender amps?  
Oh yeah   
I hate to start this debate here but whould the (analog modular) sound be any 
better through a tube amp as opposed to ...  un tube (transistor) amp?
later
