My experiences so far. I have been hearing and reading about Velvet, specially Garbos, forever. Finally I felt it was time to make the move. My previous strings were Rotosound 4000's, that I had on my bass for years, using steel strings before, mainly Spirocore. The Rotosounds were a revelation, no more blisters, and a more gutlike tone. I felt the E and A were a lot tighter than the D and G with the Rotosounds. So I chose Garbo light, hoping to get about the same tension on the D and G as the Rotosounds and then a corresponding tension on the E and A. To my surprise the Garbos felt a bit tighter than the Rotosound D and G. The Rotosounds must be really light. On the other hand I got the uniform tension with the E and A, which I think is a cool feature with Velvet.
So playing did not get "easier". But I do get more sound, both in volume and definition. If you try Velvets, I urge you to let them sit on the bass for at least 14 days, a lot of things happen in this period.
Well two days ago I unpacked my bass after the rehearsal with a trio I play in the day before. Tuned the bass up (it is still losing a bit). When I got to the E string there was sort of a "clanck" (I think), and it started to sound like I was using a fuzz pedal, a pretty loud buzzing sound. Luckily it is not the bass, I suppose the winding somehow got loose(?) So now the old Rotosound E is back on, sounding dead. I think I will take responsibility for the incident, since the Garbo E is slightly thicker, so I should probably have worked the slots a bit. I however have been so happy with the results so far, that I think I willl buy a single Garbo light E to replace it. Perhaps some time in the future experiment with the Garbo gut set.
