This is a great little trick I worked out the other day. NOTE: this is only a short-term solution. Impedence issues can occur through continued use.
If you use a Focusrite Saffire (or any other interface with more than 2 analogue outs) you can route the DAW signal through one of the additional outs, back to your amp, and then back in to Input 1.
For the Saffire (using the control window) route DAW 3 and DAW 4 to Outs 3 and 4 respectively. Set your track output to "Mono 3" and this will send it out of Output 3. Simply run a lead from here, back to the input on your amp, alter the settings / cab / head / mic as you require, press record and sit back and double track without moving a muscle!
Again, I must stress this is only a SHORT TERM solution. Most outputs are around 1500 ohms, wheres the input on an amp would require something around 10 times that. Prolonged use can cause damage to the amp circuits and your interface.
For those who want a better solution, I suggest the Lehle P-Split. It's a high impedence splitter, useable as both a DI and Reamp box. Run the signal as such:
DI: Guitar -> input. ISO to head / DIR to In 2
Reamp: Interface Out -> Input. ISO to head / DIR not needed.
Hope this helps.
