I purchased the Silver & black volume 1. What a great bunch of bass IR’s!!! I always prefer 15″ speakers to 10″ any day and these particular speakers and cabs are really special. 10″ speakers have too much upper mid range bark to my ears. Thanks Dr Bonkers, they are my go to IR’s for bass now. It is disappointing that a lot of guitar players don’t get involved with bass more often, especially if they do a bit of recording. Once I started playing bass on my own stuff my respect for bass players grew immeasurably. Great bass tones can enhance the overall soundscape bigtime!!
