Anyone recognise this preamp?

[Bassworm]

Hi All,

Digging around at the back of a drawer in my music room (We all have THAT drawer, don't we?) I found lots of stuff I'd forgotten about. Including a Bartolini MM5 pickup, and the preamp in the attached pictures. I've no memory of buying either. Does anyone recognise the preamp? Any idea of the manufacturer, or what bass it might have come from? Only clue on the box is the name 'BonzoBass', does that mean anything to anyone? I obviously bought it, and the pickup for a project, but I've no memory of when or what I had in mind at the time. All suggestions gratefully accepted.

Cheers, Mike.

That's looks very much like a john east made pre commissioned by Mike at Zootbass.

Here's my one, in a MTD Kingston.

Oo, it does look pretty similar. Thanks for that info. Now I need to find some info about it. Time to write to that nice Mr East possibly. Cheers!
