Nothing at all, the 1024 is a better bass IMO. ๐
It wasn't really a swap though. I reversed the pickup on the 424 and then the 1024 came up for a good price. I bought it to compare and keep the winner. Decided to keep the 424 and sold the 1024 to help fund an Eastwood Hooky 6.
Then fancied a 734a as it's vastly different to the 424, or 1024, being active, and wanted it as an everyday active bass to leave out around the house, rather than the BBPH. It's also different enough to the BBPH.
Oh who am I kidding. GAS made me do it all! ๐๐๐.
Apologies, this has turned into a bit of a hijack.
