ToneLib TubeWarmth

Nice tube warmer, sounds good. Unfortunately it - even at higher drive settings - still remains very clean, so it is hardly usable as some sort of tube overdrive, not even if you stack some instances.
But the clean tube sound is really good, also in front of another tube amp or tube preamp.
For adding tube character to some digital sources it works fine, also as a clean guitar tube (pre)amp or booster.
