Advice on preamp for a Hamer Cruise

Well, anything designed for a Jazz bass would go in there I reckon.

I've tried J-Retro, EMG, Artec in my Jazz basses. They are all different so it's down to personal taste really.

I think the East (J-retro) has three stacked pots if thats your preference but I found it a fiddly thing for live use personally.

John makes a 3 knob U-Retro unit...the pots are stacked and on cables so they'll retro fit the bass.

Where this falls down is the active/passive switch. You could just poke it into the cavity and leave it in the on position. The preamp shouldn't (shouldn't!) draw power when the bass is plugged in.

The other alternative would be to go with a 2 knob solution and use the third hole on the body for the on/off switch.
