All fuzzes are a bit different but there can be a sweet spot on the fuzz control, a notch below all the way up where the highs returns and it is more focused. More so with Si FFs because of the extreme gain levels. 3. As most point out, FFs love an overdriving amp but most ppl think that means a distorted amp.

WebJul 5, 2024 · The payoff is massive. Plus, it gives you an excuse to dust off your old, unused dirt pedals. 1. Think Volume. In a gain-stack scenario, your pedals’ level controls produce different results. Turning up the volume in the first pedal won’t actually increase it, but it will affect the second pedal’s gain. The second pedal dictates the stack ... In chemistry, pi stacking (also called π–π stacking) refers to the presumptive attractive, noncovalent pi interactions (orbital overlap) between the pi bonds of aromatic rings. However this is a misleading description of the phenomena since direct stacking of aromatic rings (the "sandwich interaction") is electrostatically … See more The benzene dimer is the prototypical system for the study of pi stacking, and is experimentally bound by 8–12 kJ/mol (2–3 kcal/mol) in the gas phase with a separation of 4.96 Å between the centers of mass for the T … See more The ability to fine-tune pi stacking interactions would be useful in numerous synthetic efforts. One example would be to increase the binding affinity of a small-molecule inhibitor to an enzyme pocket containing aromatic residues.
