These Ceramic capacitors are often found in cheaper guitars, natural sound and overall good balance. Does the job but not recommended for vintage or newly built guitars.
0.001uf: treble bleed
0.047uf: Singlecoils and bass
0.100uf: some basses, some '50s and '60s fenders
The higher the value the bigger capacitor, the darker the tone. Installing a new capacitor might have a bigger effect on your tone instead of mounting new pickups. When designing pickups, designing a wiring harness with the right pots and caps alongside will ensure the customer gets the tone they are after, and the one that you designed.
All pots and switches have a 3-4 day delivery time. Please take into account that these parts will bring your average 24h ship out time to 3-4 business days
