The bass is fine, I have a Warwick 5 String Fretless that is smaller bodied like this Alembic, no problem with reach though! Yeah he's a bit of a giant, unlike myself haha
I think I probably have a similar build as you, but 15 years on ya. A "few" years working in an IV room and desk duty have made my hands a lot more sensitive to something like this bass. I also started on basses with really long top horns.
