Bassguitar mod - Part 1

The Morgan YB-48 is a (Norwegian model only?) bassguitar that looks like this (left picture)

Stock 

Stock it has this setup:

• Neck: Jazzbass-style bridge pickup
• Bridge: Musicman Stingray -style pickup
• Electronics: Preamp/active electronic
• Volume, Balance, Bass and Treble pots

Mod

After some usage, I found myself not to happy about the sound. So, I did some mod/upgrade to:

• Neck: Fender Jazzbass '75 Bridge-pickup
• Electronics: Passive jazzbass pots (vol, vol, tone)

Here are some soundclips before/ after

Note: Of course not identical takes, so very unscientific 

My conclusions

 I realy liked the change. But, it seemed obvious to me that the bridge-pickup wasn't to happy about the passive mod. So, that brings me to Part 2 of the bassguitar modding..
