Although the Sansamp is an analog modeler / tube amp simulator. They call it 'Tube Emulation Technology'. The Para Driver is a tube amp 'emulation DI.' A pedal version of the RPM. Could never make sansamp work for me, but alot of players do.
Sorry, should’ve been clearer - I meant I don’t use any modelling in the DAW. The Sansamp is modelling (analog rather than digital though).
