The most disappointing thing about using Bartolini pickups was the hardness of the tone, but this pickup was different from the Bartolinis I had used so far.
I recommend this pickup if you play pop or soft rock.

Bart Mk1s are solid for what they are. They carry the signature low mid thump but the treble is quite sharp and I found I was rolling it off but the result sounded empty. The Mk5 Classic Bass is a whole nother level! The low mids punch through and the treble sits on top like a layer of heavenly clouds. I custom wired the inner/outer coils and it gives a j bass rasp with a p bass thump. It doesn’t sound like either, as it’s bartiloni so it sounds magnificent. if you dig the Bart vibe and you want to cut through a mix like butter, don’t hesitate. If your looking for a more “classic” sound, this isn’t it. Fat Bass Tone shipped it out fast! They had a ton of knowledge on their site, and is now my go to for high end bass electronics! They are making my sound very professional and I thank the whole team behind the scenes!
