It is in some pedals, but tradition (especially from the +9v battery era) still rules, and it's often less parts to do a vref than it is to add the charge pump. Charge pumps aren't free either, they have their own noise issues.

Yeah the input capacitor thing for sure, the lower the capacitance the more bass will be cut off before the signal enters the circuit, it's crude but it works.

You likely just need to change the input capacitor of the circuit until it cuts the amount of lows you want.

Even just trying to figure out the switching is making my brain hurt.

It's worth noting that even though the TY-141p states 200hz to 2k or whatever, when you actually measure it, it's flat down to 20 hz and up to over 16khz, I need to set aside an after noon to do the testing again soon because I have that one plus a bunch more on hand at the moment.

Check out these measurements I made. Some of the cheaper transformers have a surprising performance. It's hard to beat the price to performance of the Triad ones IMO. I have a few more on hand I need to test...

Unbalanced ones as long as they're not too far above +4 dBu. Running it at 12v would help with headroom.

The jelly bean 2n3903 and 2n3905 both have pretty low hFE as well. The BSX20 is also quite cheap and still available for now.

Hey folks, this is one of the first circuits I designed with intent rather than just sort of circuit bashing. The idea is that's it's essentially a buffer. Except it has a bit of an upwards compression effect, reducing dynamic range slightly but by bringing up the body rather than reducing the...

Do you have an example schematic of the mods? I picked up a few of these myself on the recommendation of the DIYSB forum, but I'm not exactly sure what the safety circuit looks like

You might get more help on a forum more dedicated to embedded devices.

Same, I don't know what I might want to build in the future, might as well build up a bit of a stash and save on later shipping.

You should notice one side is beveled and the other isn't, the datasheet should tell you how that affects the orientation.

Check the data sheet, there is indeed an indicator for which side is "up".

As a FET based compressor I'm pretty sure this will have the distortion you're so keen to avoid.
