Whether you need it or not is for you alone to decide (well maybe with input from your band mates), but the CLR's are easily worth the asking price, and more IMHO.
Just don't tell that to Tom King, we don't want the CLRs to cost what they are really worth
To get the best out of your Axe you need to amplify it with something of a similar quality as the Axe and your guitars.
When you use speaker cab IR's and perhaps acoustic guitars, backing tracks, a band mix, bass guitar (and the list goes on - I'm sure you catch my drift) you need something that is as neutral and true to your source as possible.
I haven't found anything up to 2,5-3 times the price of the CLRs that sounds as good as the CLRs. That is quite astonishing really.
Think about it this way, just like the Axe is great value when you think about just how many great amps you get for the price, well the CLR is equally good value as with quality IR's you now have all these cab, speaker, mic and preamp combinations available for the price of one CLR. And then there's the added bonus of the CLR being so transparent that it's great with acoustic guitars, bass, vocals, keys, backing tracks, a band mix any source that you'd need a FRFR system for and it's a really great mini PA too.
It never seize to amaze me that guitarist will gladly pay huge sums for their guitars (yep thats plural) but will skimp on a crucial element in their sound like the monitor solution.
A CLR will enhance and better your sound and experience with all your guitars, and with your piezo equipped Parker, you'll get great acoustic sounds if you tone match a great acoustic stem.
I did an extensive review of the CLRs a little over a year ago (search on my user name to find it if interested) and my fondness for the CLRs have only grown since then, my CLRs keeps performing perfectly in every situation that I put them in including very challenging acoustic environments.
Now for the bit in the local tongue:
Jakob din nærige hund, få så den muldvarpeskinds pung ud i dagslys og bestil en CLR, dine ører vil elske det, smukke kvinder vil sværme om dig og du kan takke mig senere
Agreed, very well put
