Yep this is all true. I actually have a Mexican Player Plus Jazz V bought used from The Gallery earlier this year modified with an onboard Sadowsky preamp. I'm not a Fender fanboy but I really like this particular one.
That applies to Fender rather than Squier in my experience. I've had several of each. It's to the point where I don't understand the immense price difference between the two brands.
I have an NT AND a BO Warwick 5 and neither B string is better or worse than the other one. So I would say any German Warwick 5 based on that as I've owned a few in the past for comparison.
Dunno if it's a fashion statement dude as a lot of people including myself just simply don't care for them. As always we have to factor in personal taste I guess ☺️
Told myself I needed a posh "industry standard" pair of headphones for late night silent practice. In came the famous Beyer DT770 PROs. Out went the famous Beyer DT770s via E-Bay! They were no more effective (at that task in particular) than my less than half-the-price price AKGs from Richer Sounds.
Sadowsky preamp whether onboard or pedal format. Sold pedal and have the onboard on my Jazz Bass. Zero regrets especially when playing live. Agree with all the flatwound comments posted so far,I just don't understand them in comparison to rounds.
