I had Cliff Bordwell put Big Singles in my custom ball bass and I really love them. Coupled with an Audere pre-amp you really can bring out the agression in the PUs with a dash of mids boost. But I love the bridge PU tone with a dash of bass and a dash of mids. Hmm creamy.
Davo
It's the 'creamy' tone of these that I don't like. They sound much more like humbucking soapbar pickups than 'jazz pickups on steroids' to me. IMO, they 'suck the J out of a J bass tone'.
If you are looking to make your J bass sound fatter, less grindy, more creamy, with fatter low mids and mids, these are great. However, they sound nothing like a 'single coil J on steroids' to me.
Regarding hum, they hum like any other single coil when solo'd. Given how fat they sound with the bridge pickup solo'd, I'd HIGHLY recommend the Big Splits over the Big Singles. In my indirect A/Bing, they sound virtually identical, and solo'ing the bridge pickup with these 'Big' pickups is quite amazing if you dig the 'Jaco burp'... MUCH fatter and smoother than any standard J pickup.
However, none of these 'Big' pickups are appropriate IMO for 'juicing up' a J bass. They are cool if you like the way a J bass feels and looks, but would rather have a more modern 'soapbar' tone.
IMO and IME.
