I've been on the lookout for a lightweight active Jazz bass for a while, or at least a lightweight Jazz I can put a J retro in. I bought a Silver Series Squier a while back which started off at under 9lbs - changed the neck to a Mighty Mite Jazz neck, installed a J retro and Hipshot Bridge. After all those mods it weighed nearly 10lbs!
A few days ago I bought a Squier Deluxe IV on eBay from a guy who, it transpires, is a Basschatter thebassman75. In as new condition for £205. But even new they aren't that dear, £255 or so.
I've had it a few days now and can't believe how good it is for the money! It ticks all my boxes. It looks great - this one is all black, rear routed so no scratchplate (not everyone's cup of tea but I like it) black headstock, black ebanol fretboard increases the stealth look. It is lightweight at around 8.5lbs - I was practising for around 4hrs yesterday (lots to learn atm) and have *NO* backache today. The neck is lovely - I had to raise the action when I got it home as it was too low for my heavy-handed playing.
The active 3 band eq. is surprisingly good - not as good as the J-retro but I can get the sounds I want out of it. The tone from the pickups is not quite as rounded as the Silver Series but, well, good enough for my purposes. It sounds like a Jazz bass should, anyway. And even the bridge is more Gotoh-looking than the usual BBOT. Tuners are a little uneven but work just fine. Probably the first cheap bass I have bought that I am not tempted to tinker with.
I don't recall seeing these flagged up very often - but as a lightweight active Jazz they are worth considering.
