Well, I finally got the last piece of my rig together... the Aguilar GS112 just arrived and is perfectly matched to my Mesa/Boogie WalkAbout and Carvin 5 string fretless. The sound is really huge, and can be tonally shifted from quite brite and punchy to very warm and thick! It's light, powerful, and much nicer sounding than the other combinations I tried. This took nine months and a chunk of scratch to put together... but the end result was well worth it. Best of all, not only does it make me sound better than I am, I can carry it all without blowing out my back!!!
