Hey, I recently picked up a used Spector 5 String NS-5CR (pre Rebop) with Aggie OBP-1 Preamp and Seymour Duncan Basslines Active Soapbars. I have an extra Tonepump preamp at home that I ordered from Spector a while back. Can I use the Duncans with the Tonepump? What will I need to do as far as pot values? I think Duncans use 100K volume pots according to their website schematics. I'm not sure what the value of the OBP-1 volume pots are. Any ideas? Can I use 25K volume pots with the Duncans? Thanks for your help.
