And yet... no decent gtr I know doesn't use a tube amp. And very typically they have far better understanding on sound than most bass players. The level of comphrehension there is not even close to the vast majority, ime.
Personally, I've tried the likes of TH, Bergantino and Thunderfunk etc. The latter two were nicely built, no doubt, but for me, didn't really cut it.
So, imv, you need a tube at pre stage at very least. That's not beyond the market adding a tube so the bass player carries a 12lb amp which is, imv, THE number one consideration for most.
