I have been very luckly and typically have not insured my gear but then again I only take my workhorse stuff for gigs...which is what it is..dependable and not "fancy"...(not cheap either but replaceable)
most likely nothing is going to sound good in a basement and in my experence what happens is people start to trun things up and then: EAR DAMAGE...so IMHO it is best to make (or purchase) some acoustic treatment or foam.....

SOS also has some great build it yourself...
I had a strange Dimarzio pickup. in a cheap guitar, in the neck position, back in 89 or so....I was so dark and thick..I think it was a single coil...anyone know what it was?
I just grab this from the THD hot plate manule:
Q. Can I run a 200-Watt amp through the Hot Plate?
A. NO! The most powerful amp you should use with the Hot Plate is 185 Watts RMS.
my thought is there are so many different types of Marshalls; therfore, many different sounds so, why not if an amp is really close in specs should the poor amp be excluded....
