I needed to turn my active bass passive. This harness was very well put together and easier to install than I thought it would be. The bass still has a powerful sound, but with the passive tone I was looking for.

The passive prewired harness was a good replacement for the worn out Ibanez controls on my Soundgear 4 string bass. The holes in the body had to be enlarged slightly and the included 3/8" jack was too short( I needed a 1 1/4" length jack) so I used the original jack. New knobs are needed for the slightly larger control shafts. Combined with the Delano pick-ups, the Ibanez bass sounds better than ever, very powerful and good sound balance.
