- One small swap of wires improves the circuit impedance, resulting in ~25% more volume, a brighter/meaner tone, and slightly less noise.
- A bleed resistor was added to the power capacitor bank. This has no effect on the B+ voltage when the pedal is powered up. When powered down it will dissipate the stored charge in the caps over the course of about 10 minutes. Without this resistor is can take a week or more for the caps to self discharge. The point of the bleed resistor is safety, related to servicing.
- A bleed resistor was added to the circuit input to minimize the click sound from the stomp switch.
- Wiring layout improved for aesthetics.
Anyone who purchased an LBII pedal before May 15, 2017 can have their pedal updated to Revision A for $10. Owner is responsible for round trip shipping charges to LBA. Email email@example.com to schedule an update to your pedal.
