Brand new, never used. These are German-made and have a great reputation as a Music Man upgrade.
The makers claim a very warm bass and low-mid response, accentuated mids and a bright percussive top end, i.e. Stingray clank, whether in active or passive mode. I was thinking of using it in my (passive) SBMM Joe Dart, but decided in the end to stick with the OEM pickup (not least because it's white and matches the rest of the hardware - a case of style over substance, perhaps, but there you go!).
These are £99 from Bass Direct and often more elsewhere, so I think £75 posted is a fair price. If you can collect from Mapperley in Nottingham, I'll knock a fiver off and provide tea and biscuits. Can't say fairer than that!
