I recently acquired an Ibanez Musician (MC924) bass from 1983. The stock active electronics are gone; she's passive now. I would like to make it active again. So now i have to choose what onboard preamp to put in. John Easts U-retro was first choice but is too expensive. I hear Aguilar and Bartolini also have good products, but i would like to know if there is more to choose from... and of course your opinions on them. Budget is max 200 euro, but less is even better. The pickups are of normal passive impedance BTW.
