I had a Thunderjet identical to the one at the top, it was a work of art, just beautiful, even the Mrs liked it, BUT, as pretty as it was, I couldn't get on with it at all, neither could the chap that bought it from me.
I used it live once, but couldn't get any kind of sound I was happy with, it was very middy sounding, no top end at all, no punch, and the rest of the band were grimacing at me mid set wanting me to put the Jazz back on, which I did, and hey presto, the bass could be heard again.
Stunning looking bass, I was so happy the day I bought it, but I only kept it a month and away it went, shame.
