I'm a bassist, and the conventional wisdom on the internets is that the Sovteks were best for bass, the green Russian and civil war being the best. I built one to green Russian specs and I'm happy with how much bass it lets through.
It's quite robust circuit though- legend has it that even at the old New York factory, if they ran out of one type of cap, they'd substitute the next closest value until they got stock again, so there are many variations. If you have one that is close to 'vintage' NY spec (whatever that means) then a Musket will get you the Russian end of the spectrum. If you're handy with a soldering iron,
it's really an easy circuit, I made mine on perfboard and it still fits into a 1590B
