The G3a was the final Pearce guitar amp.  A third channel was added, voiced for amplified acoustic guitar.  I’ve heard that fewer than 50 were produced.  Changes from the G2 include:

1. •New script logo
   

2. •Three channels
   

3. •Midrange control now on one cocentric knob for frequency and cut/boost
   

4. •Tube distortion circuit on Channel 1
   

5. •Headphone out and level control on front panel
   

6. •Two-way speaker (full frequency response for acoustic channel)
   

7. •MIDI control for channel selection, boost/crunch, limiter and input
   

8. •Stereo aux-in for keyboard/CD input
   

9. •1U space provided for third party multi-effector
   

10. •No on-board reverb
    

11. •Four effects loops
    

After Pearce Amps folds, Dan Pearce apparently takes the design to ART, who offer it as their ADP150 combo
