I'm debating about switching the pots for the bridge pickups on my Les Pauls from 500K to 250K (or 300K if I can find one) and it's got me curious. I was talking about it on my JB thread, but I figured it might be worth a thread of its own.
My reasoning is I have a bit of an EQ going before my amp in my HX Stomp just shaving off a bit of high-end subtly (less than 1dB). I wonder if I can do without it if I switch to a lower value pot. Is there a way of predicting by how many dB the resonant peak would be attenuated with pot values? What is even the resonant peak of the JB?
I'm a huge nerd for measurements. I love reproductability and predictability. And I'm sure the result won't be the exact same because the resonant frequency on a JB is not actual high-end but high mids, but if I can get some numbers, I can at least start picturing what the result would be and if it's going to be what I'm looking for or not.
I like the tone I get from a single 500K for the most part. Especially with flabbier amps (or, in this case, amp sims) like Rectifiers. But the EVH model I am using right now is super attacky and sometimes need taming. The JB is doing the heavy lifting as it's EQ'd very much in the ballpark for what I want right now. And I like that with a higher value pot, the pickup feels more "open" not just in the highs. The extra high-end (or I suppose high mids in the case of the JB) shift the focus away from the mud in the low and core mids. So I wonder if won't be making things worse rather than better by dropping down to 250K.
The other main question is if I can maybe have what I want in a push pull. Like have the pot behave as a 500K one if I pull up on it, and as 250 if I push down on it to have the option of having both if the mood strikes or if I'm using a different sim, or if I'm going for a brighter tone for whatever reason.
So... any ideas? Hit me up with some mathz.
