Before I purchased mine, I tried/played/borrowed many heads. I knew I wanted SS and light, so class D seemed the way to go.
There was a GK I was impressed by, the Aguilar didn't do it for me, nor any Mark Bass, some were way out of my budget, and others bigger than 1u in height.
When I tried a TecAmp Puma, it ticked all my boxes plus it was easy to get a great sound straightaway with my bass. So when one became available on Basschat at a more than reasonable price I bought it
If you want to have a fiddle with it on Saturday you are more than welcome?
