Modding a 14-Watt Amp Kit

I've been looking at these 14-Watt amp kits from Nightfire for a while. They have a few different versions but only the PT2399 Delay version has schematics available.
I'm assuming the other versions are similar, minus the delay circuit. The designer was thoughtful enough to include a buffered input. Nice to see a small SS amp kit that actually appears to be designed with a guitar in mind.

I heard one clip of one of these cranked up high and it sounded pretty good. I liked the few sound samples I was able to find but I'm wondering about adding in another gain stage or two so the amp could get a little bit of light breakup a little sooner. Could I do this using FETs maybe? Would it be best to add a stage or two before the tone stack or after?

I suppose it would be nice to mod the delay section a bit as well. It appears to have most of its control options bypassed.
