I'm glad you're making progress.

On the 1010LT, the non-XLR inputs are all line-level inputs.  They are
not designed to be connected to a guitar.  The XLR inputs shouldn't be
connected directly to a guitar, either.  I think those inputs are
low-impedance, balanced mic inputs.  You should use a DI box to match
the high-impedance guitar signal to the low-impedance mic pre on the
1010LT.  I guess you can plug the guitar in to either type of input,
but as you learned, it will be too low, and I think it probably would
sound like poo.

I think the manual must provide some insight into what should be
connected to the two types of inputs.  My Delta 66 manual does. 
Though I guess it doesn't really tell you what NOT to plug into it.
