Replacement pre-amp for Yamaha TRB mk1

[brick]

As the title would suggest im looking to replace the pre amp on my Yamaha, so far have been looking at the John East U Retro 5 knob and the Bartolini 5.2 pre amp

Was just wondering if any other TRB users have changed the preamp on their bass and if they had any recommendations other than the ones above

Cheers

I'm about to order a Glockenklang for my BB. May be worth a look for your TRB!

East and Bartolini preamps are some of my absolute favourites...they will not fail to impress!
