This speaker change, made the amp sound more detailed, and improved also the low end, and top end response, compared to the greenback, wich focused more on the midrange. Since the amp is a very small box, and the speaker is very efficient (100db), I had to use a cover to prevent feedback to the reverb tank. With this speaker, the amp is very loud, and I had to increase the negative feedback a bit (compared to when I was using a greenback) to smooth things out.
When used with a 1x12 extention, I like the G12h 55hz heritage speaker in open back cab, wich combines perfectly with the gold and improves the response of the combo.
