Rosewell Amps

13/11/2025

Thinking of having an open evening or a weekend afternoon at the workshop within the Westfield centre, this would take place in the main hall.

I have several custom amp designs almost ready, a couple are Dumble inspired, some are my own.

There will be a short talk introducing each model followed by a demo, I have a couple of guest players in mind, afterwards anyone is welcome to have a play,

Early days yet, it would be in the new year, just putting this out there to test the response, please feel free to comment, share and any suggestions?

Free entry of course! Refreshments will be available.
