OK, after much discussion Japan have come to the party with a definitive answer (well, as definitive as ESP Japan can get). This straight from the 'horses mouth' as it were:
1. Pickup change
Acceptable. No extra charge for switching to Seymore Duncan from EMG. Need some difference for the opposite case.
2.Hardware color
Acceptable with no eztra charge.
3.Paint change
Acceptable, but need a quote first.
4.Control layout
Basically, NO. This is too much trouble for Standard production line. Sometime we do, but price will be much higher than regular models.
Donc a priori rien a voir avec algam puisque ESP accepte de faire ces changements si j'ai bien comprit le forum australien
