Here is a 2001 Modulus Flea Bass (FB5, now known as Funk Unlimited) 5 strings with important mods (mainly Delano pickups with coil tap and Aguilar OBP-3, see below). This is an exceptional bass, with a distinct growl and likely the most comfortable neck I've ever played. The added neck pickup and coil tap for the bridge humbucker makes it super versatile.

I bought it used from a reputable music store back in 2006 in Switzerland (I still have the paper receipt), I believe I'm the second owner. I gigged extensively with this bass, I would rate its condition as 7/10, mainly because of 1-2 dents and lights scratches. I made sure all of them are visible in the pics. None of them affect playability. The frets are still in great shape.

The mods: in 2011 I had a professional luthier in Switzerland do the following:

replace the original nut with one made out of carbon fiber

replace the stock preamp by an Aguilar OBP-3, with two frequencies selectable for the mids

add a neck pickup (the FB5 stock only has the MM-style humbucker), this is a Delano JMVC 5 FE/M2, technically a split-coil but really sounds like a hum-free single coil

replace the stock "basslines" MM humbucker with a Delano MC5 FE with a coil tap to select the bridge single coil (hum-free thanks to phantom coils) or to have both coils in parallel for that typical Stingray sound

with the added neck pickup and its volume pot, I needed a new pickguard (though I still have the stock one, see pic), the one currently installed is made out of maple, with a ramp. Note that the stock pickguard completely covers the holes of the neck pickup and its pot, so could be used to mask them should you wish to revert the bass to its stock configuration with just the humbucker.

I think all these mods add a lot of value to the bass: it can still do a convincing Stingray tone, but it now has so many more! I can record and share soundclips upon request.

The bass is currently strung with D'Addario EXP 40-60-75-95-125.

A local pickup would be great, but if not I plan on shipping the bass in a hard case packed with padding in two nested cardboard boxes. The case is a Gator TSA bass hard case, brand new! See the pic, it still has all the tags, etc.

Thanks for looking!
