I want a small (I've got an Acoustisonic Jr)  super clean amp to play an archtop using  various combinations of magnetic pickup, acoustic transducer and an FET microphone.  The goal is to capture the sound of the unamplified guitar I hear playing in my easy chair w/ the f hole 12"  from my ear.  I plan to build a delay/reverb unit into the enclosure which will probably house an 8-10" speaker

Before I engage in a gratuitous design exercise I thought I'd ask here for suggestions/pointers to designs w/ similar goals.
