Would there be any benefits from increasing the input impedance of the SD-1/TS9/DS-1 from (around) 500 kohm to 1 Mohm? It seems other Boss pedals have a 1-Mohm input impedance and I'm curious as to why the SD-1, DS-1, or TS9 have about half the input impedance.
Thanks for any info.
Lowering the Input impadence "shaves off" abit of the edgy harshness, and contribute to a darker, smoother sound (some would say muddy). that is by my own ear at least. I increased my TS-9 input to 680K, and I recives humbukers much better now.
Thanks for the info, Phorhas. :D
Yeah, guitar pickups respond differently to different input impedances. There does exist a 'sweet spot' for pickups (though not the same for all pickups) and it seems to be in the range of 300k to 700k...but then again, what is a "sweet spot"? It's all defined by what your ears like.
When you mess with input impedance, changing diodes, ICs and capacitors, just be objective. Most of the time it makes an ever-so-subtle effect that you couldn't hear it in a side-by-side recording, but it makes you feel better about it somehow. There's some people who I could get to pay me $50 to mod their pedal, and all I would do is open the box and put in a new battery snap and give it back to them. They would swear there was an amazing difference. However, some people aren't quite that naive, fortunately...so I encourage you to be one of those fortunate people. That way you can come up with a mod to try and you will be able to tell if it actually made a desirable difference. Happy modding!
