Yo, Pete!
@Peter Durso, you are now member #1651 in the Fender Rumble Club. Congratulations and welcome. Put that number in your TalkBass Signature for safe keeping. Then make yourself at home here and on
your Rumble Club Wiki page, the repository of all Rumbling wisdom and knowledge.
You're right, the 140w 200 15" doesn't
seem like it would be
that much difference from the 100w 100 12". But, for some, it's enough difference to make a difference! As with most musical considerations, it's all in the ear of the beholder.
So, Peter, how about telling us a bit about yourself, such as your bass experience in general and your Rumble journey in particular? We have all kinds here so you're bound to fit right in. But we all love to ... ... ...
Rumble On!
