Just bought an Ultra Jazz and I love it. For me, it’s the most comfortable bass I’ve ever played and has a lot of tonal options. However, I’m always looking to make something perfect…. Curious is anyone here has upgraded the pickups and/or preamp with positive results? I do like the sound as is, and a noiseless instrument is essential for me. However, not massively keen on the mid control as it sounds a little harsh to me. Have been considering John East pre with maybe Bart’s?
