They were made 2012 - 2018.
I have a 50w Paisley Blue Sierra , and it is to me a paisley plexi , thick and delicious. It has a 2x12 closed back matching cab,
for the Carlos or Derek Trucks tone it is the best I've played.
Les has an HXDA and can offer his insight
The paisleys are rare beasts , the run had a limited amount of the material .. and it certainly isn't for everyone ... being an old hippie ..well it's just love
My DG30 and 2x12 is a cleaner and more versatile amp , together well.. just MAGIC
