Thanks for posting a great video demo. I think it's going to be a reference for many guys going forwards. Some basses lean to certain styles and strings. Old P basses take flats like no other.
To my ears the P bass sounded so nice finger style and easily the goto vanilla sound on bass. The MM was a close 2nd for me. However...slap and the MM rocked. I thought the Riccy had the early model bass cut circuit engaged which is why it sounded so thin. So that would need some re-soldering or some heavy post EQ to bring that bass alive in the mix. The tones are there but need coaxing in the mix.
Finger style wise...apart from the fret clank / bark which is unique to each bass style...the basic tones for each bass can easily be EQ'd or mixed to sound the same or copy each other.
GMC, great thoughts, thanks so much. Stop by anytime and feel free to chime on whatever is being discussed. Better yet, if you own a combo, post a picture and we’ll reward your effort with a membership number. We’d enjoy having you as a member. Think about it.
Not a bass amp review phrase I'm familiar with.
