That is indeed the series. You can go into any of the Cantiga sets on the SBM menu and pick the bass only sets in the tension you want (I use medium tension Cantiga with the string Dogals) and you will be OK. The actual numbers on the bass string packets when they arrive will be 516R, 515R and 514R. These are part of the 510 set. To save on shipping I'd also get a set of Sonata basses at the same time.......PAN A575 wrote:Thanks Peter. I should have asked before I ordered the Dogals. I could have added the Cantiga to the order and possibly saved any addition shipping cost. If the Dogals work out as well as most reviews here, I''ll order more and include the Cantigas. Would that be the 510R Bass?
