Finally done with the GSR clone. Done a A and B comparison with the Biyang Overdrive I have.
I immediately notice that what I have on hand are two completely different overdrive pedals. The GSR have a very strong presence and excels in the highs whereas the Biyang is very warm and mellow with a very soothing kind of overdrive. The Sustain is good on both but the GSR fares slightly better and can be turned louder than the Biyang. When gain is turned to max on both, the Biyang tends to be very sharp and harsh whereas the GSR is able to maintain it's tone throughout.
All in all, I would personaly keep both pedals on the board as they both serve different purposes. The GSR for lead and the Biyang for a blues feel.
