Right now Sweetwater is selling this package for $180. I don't have any Waves plug-ins and am still using the EQ and D-Verb that came with Pro Tools. Would this be a wise investment?
It's $168.75 at Amazon. http://www.amazon.com/Waves-Native-Power-Pack-Standard/dp/B0007CG5DC
Renn Axe, Q10 and L1 are GREAT plug-ins! I say, go for it if you've got the money available.
The Native Power Pack is a great bundle. It's one of the first Waves bundles I bought & you get some very powerful tools worth twice that price (which is roughly what I paid years & years ago). It's also a good way to get in on the upgrade path: cheap buy-in, great tools for the time being, good value on the trade up. If the wallet's fat from tax refunds buy it.
