Live I run two paths through the Axe 3. One path is my normal guitar patches. The second path is either fed by a piezo if I'm playing a guitar with a piezo, or an acoustic simulation patch if I'm playing a guitar with just mags. Each path has it's own output. I have the tube pre in the piezo/acoustic sim path to warm things up bit, but I'm burning an entire amp block for just the tube pre. Can I get something similar to the tube pre out of any of the drives? It'd be nice to just have a drive block in there and free up the amp block.
