The SC Alembics are great. Interesting as they have a filter preamp. A more affordable and conventional one is the Chowny SWB, which is a very well made guitar (I have an Indian made one, the newer ones are reportedly even better). Very slim necks if you’re having hand issues.
To get to the sound of the Alembic, a short scale filter preamp ACG nails it. Second hand they can be ridiculously undervalued.
