For recommendations, probably the three best options I have found that I liked most were:
EBS ValveDrive - fantastic tube character, nice Fender-circuit EQ, great overdrive
SansAmp VT Bass DI - this thing just sounds amazing. Solid state, but still adds a very tube-like tone, lots of presence. I absolutely loved mine, until I destroyed it accidentally
Any of the Darkglass. I owned a Microtubes X which I liked a lot, but not the preamp version with full EQ. The Vintage Microtubes, B7k, X7, or Alpha/Omega in their preamp versions would be worth checking out for sure. I own a sim of the VMT and B7K Ultras, and it’s amazing.
I start to document my love affair with the ValveDrive here:
It’s one of three pedals I have left
