Compare to Alembic Blaster. Includes 1.6mm PCB jack plate & populated preamp PCB. The jack plate is compatible with a PRS Silver Sky and Fender Stratocaster. Some unlikely, modifications may be necessary though. 
 
Now includes the 9v battery snap with purchase. Jack plate options are now available.
Note: The HASL shiny finished surface is imperfect and may contain minor scratches.
