This is a Valco made, 1965 Supro S6422TR. I've owned a few of these and they never disappoint. Amazing vintage tone! Basllsy and gritty when pushed. Very touch sensitive, so you can clean it up to a sparkling clean, even with the volume on 10. This video cuts off before I can demo the tremolo. Search my other videos for examples of this model's tremolo. It's amazing as well!
