@@user-nt8oz4id8x The YYZ is also a very good sounding pedal.The 2112 just has more options.I love preamps and own more than a few good ones.That said the Tech 21 products are top notch, you can't go wrong with them.
The VT Bass DI SVT emulator is the best Bass preamp i have ever used, i can get the exact same sound our of my Orange Guitar Amp that i get from an Ampeg SVT its wonderful.
