There are two clones I'm using, either from @SNCpre or @BaZZZZZ.I'm likely going to avoid the "X" series route so as to maintain the traditional level of compression I'm used to with EMGs. So either their standard PJ set or PJA for warmer treble.
Where can one find a 9v Haz or clone preamp?
Since you mentioned you're bass is not a Spector, I believe a standard SNC Haz Clone (which has a fixed knob layout) would be difficult - but I think Sheldon could make it custom. The Baz THB3 is also a great sounding small alternative. No idea about how postal services from Russia are affected by the current situation though.
A great sounding pre with plenty much growl is also imho the EMG BTS with the right settings set via dip switches. Not expensive and fairly good available everywhere.
I've posted my preamp samples before but here it is again. The Spector used here is a Euro LX with PJ pickups with DR DDT and the EQ is always boosted to max.
Since I don't know what bass is yours, a bass loaded with dual coil pickups would sound less growly.
