Hi, I have a Takamine EAN20c which comes with a CT4B preamp.

I'll use it in a rock/pop band in very big venues at very loud monitoring levels (with a high risk of getting feedback). I mainly play hard strumming.

I'm thinking about the M1 or the new M80 and the VENUE DI.

I'm also wondering if i can take any advantage of the guitar built in system. Wood worth it mixing both signals. How?

Another question: Passive or active?

Thank you very much and sorry for my English. I'm from Argentina.
