 Both of these are fine amps, particularly for just starting out.  The 
 Silvertone is very small, with simple controls.  The Fender is far more
 complicated as it has DSP innards that allow it to "fake" a bunch of different
 amplifier tone profiles.  But both are solid-state amps... and Robert and I

 Not sure exactly when I'll start this project .. stay tuned!
