The HA8000 is not going to work for this at all. The HA8000 is a Distribution amp, meaning it takes one signal, and proportionally distributes it to however many outputs it has (in this case 8).
A Direct Box is the way you want to, it's inexpensive and will allow you with minimal fussing to connect your guitar to the 1010LT. Some Direct Boxes have RCA outputs, some only have 1/4", so depending on the features your direct box has, you may require additional audio adapters.
