    Thanks to everyone for their input, I have finally found an excellent overdrive sound ..exactly what I was looking for...So how did I do it?
    First I changed the Cap, I have never been a fan of .047s they sound a bit "honky" to me, so I tried several and found that .056s were perfect for me, I then tried different diodes. 1N4148, Schottky and Ge 1N34A..the 1st two had almost no effect - not enough output probably, 1 x Ge 1n34a was subtle but nice so I tried 2 of them and it is perfect.no volume loss that I can notice and a warm, fat, smooth growl...and here in Peru 1n34a diodes are 5 for $1.
    The diodes are just wired in like another tone control...pots here $1...countless hours figuring it all out but a total cost of less than $10...one happy bass player here :D

    Sorry I donĀ“t have anyway to record decent quality..since I posted I took one diode out..it was a bit fuzzy when i turned the amp up loud...what I have now with just one diode is just a punchier sound with better and clearer separation of notes and a nice growl on the BEA strings when played with clean amp settings...part of it seems to be from the different cap and part from the diode, there is a little growl when I take either one of them out so maybe the 0.056 cap has put the resonant freq of the bass to the ideal spot for growl and the diode is accentuating it....some of you tech guys can probably explain it.

    Can you diagram your wiring for us?

    wire it in exactly the same as a tone pot just change the cap for the diode or diodes
