[quote name='Norris' post='213639' date='Jun 6 2008, 08:46 AM']Someone has given me a kit, still in original box with instructions and everything. The "CD-J SUPER-MIX" kit contains circuit board, active/passive switch, socket and internal gubbins to convert a Fender Jazz to active. It was made by Ampro Electronics from Wallington, Surrey - circa 1987. I am NOT going to fit this to my bass - especially as it involves routing out a cavity for the battery, but wondered if anyone has ever heard of this kit, whether it is recommended and if it is worth anything. Obviously, these days you would probably just buy an active bass in the first place. I'm not a fan of active guitars myself, having had batteries run out on me way too many times in the past (hence my old Aria is 'retired'!).[/quote] Hi Norris. The Ampro Activator was a fantastic piece of kit. I used to have one fitted to a Precision Bass and the transformation was unbelievable. I believe Ampro are now out of business, and their kits are highly sought-after amongst the bass-playing cognoscenti. The down-side is that you'll probably have to route out for the 9v battery, but the results are well worth it; better than a Stingray and without the studio earthing problems! In these days of just about everything being built on a budget from cheap Chinese components, it's hard to find such a well-made piece of professional kit. If you've still got it get it installed on your bass. You won't regret it.
