Code is BOOM-20-OFF .
Many of their amp sims (Nembrini built) are currently priced at $19.99 and the coupon allows you to get one for free.
 Also, their Knifonium, Oberhausen, and Thorn synths are worth a close look imo.
I think their marketing plan is to do anything possible to get new customer and then rely on the strength of their products and pricing to extract $300 or so out of that new customer. LOL, worked on me over the last year, I’m using their stuff for about 85-90% of total plugin usage now and the improvement is not subtle.
