Tanglewood TW55A acoustic bass preamp question

[fifty1fifty]

Hi all New here but will cut straight to the chase: would anybody with knowledge on the Tanglewood TW55A acoustic bass know whether they have recently changed the bass's preamp (specs), from a Fishman Presys + to a Fishman Matrix Infinity (or equivalent) - or vice versa?

Why I ask is because I played one today which had a Matrix Infinity (or equivalent), and I wanted to check whether that was correct for the model?

Thank you for your feedback!

UPDATE: Spoke to the Australian distributor and I am told the preamp is a Fishman Sonitone, and that Tanglewood change their specs on the occasion... interesting. Apparently a good pre and doesn't get in the way of the sound with too much processing. Has anyone had experience with the Sonitone- particularly on a TW55a?
