How do you like the XMG+ now that you've had a chance to try it? It looks like a unique mod based on Rob's Tone Comparison Chart in another thread here.
It's a great module, giving you some excellent overdriven sounds. I also tried pushing it with a tube screamer and also with a booster, and it handed it great. From what I've read, it seems like it's supposed to be a highly overdriven module, but I didn't find it to be any more overdriven than any other module that I've had so far.
