A few questions: 1. Will any pedal buffers between a bass with classic stacked controls with resistors interact with the way the electronics work together or with a valve/tube amp? I ask this because I gather from reading that some preamps work 'better' with a bit of resistance and that is a big part of the vintage vibe and tone these controls have. 2. is a series/parallel mini toggle possible to add to this configuration? I have never seen anyone discussing resistors in a p-bass or with series config but if it is possible, I can only presume that only one resistor would be used (they'd interact, no?)...but if the resistors do more for the setup than prevent interaction, perhaps it would be worth including across the board. Thanks for any insight y'all have for this guy.
