Comparison between Nembrini Audio 8180 and the Heavy 51 Lead by Overloud TH-U. Both are emulation of the Peavey 5150 Block Letter. I used exactly the same IR. No Post-Production, No EQs, No Comps. Between the two amp sims I had to use a very different Eq because one responds very differently from the other. So I tried to get the most similar sound from both. Let me know below in the comments what you think and which one you prefer! ✌️🎸
