I installed the above strings on my Pono Cedar topped, mahogany back and sides tenor. The sustain is really remarkable, I don't know if it's the tuning (DGBE), the strings themselves or the woods in the instrument, but as I said the sustain is amazing. This is my first experience with Romero/LaBella strings and I am impressed. I may try this mfrs. strings on another instrument. Has anyone else out there tried these Baby Baritone strings? if so, what do you think.
