Double Bass Ampeg Baby Bass Spirocore Solo size question

[bigmikebass]

Hey friends, I have read through tons of threads recommending spirocore solo's tuned at concert pitch for the BB Bass. There are two varients, one for 4/4 and 3/4, and one for 3/4. Can anyone give me a definitive answer as to which ones will fit the Ampeg best. Mine is the later version with the DB type tailpiece.
Thanks in advance for your time and patience.
Mike

Can you tell us the mensure?

Not in hand at the moment. But will report when I receive it. Thanks very much.

The 3/4 set will be ok.

I know Ruben Rodriguez uses the 3/4 size. That's the definitive answer IMO.
