Neeed to get my volume to 11...

[larcenasb]

Firstly, I'm glad to see the forum is here and seemingly unchanged since the new ownership. You guys are doing great so far!

I've padded an Alps pot for a Crack build before, but is the 75K/33K resistor padding the same for a Crackatwoa? Because the C2a already has resistors going to the volume pot. So, how would the padding be wired up in this case? Like the title says, I'd like to be able to get closer to 11 on my volume range! Right now, I never have to go past 5 with even my various 600-Ohm AKGs. Any guidance would be appreciated. Thanks so much!

You could move the resistive pad to between the selector switch and the balance pot, but it'll sure look a lot different than it would on the volume pot. Given that you have a balance pot, one of the larger reasons to implement the pad in the first place is already resolved.

Hi PB! Thanks for the lightning quick reply again. So, you mean move the current resistors at the pot to between the selector switch and balance pot, or just add the 75K/33K padding to between the selector and balance pot? Thanks!

In case anyone else is curious about doing this... For the time being, I'm experimenting with using Peace APO to reduce the gain by -12 dB, and also trying -15 dB. Nice I can play with different amounts of attenuation and no soldering required. And then if I want, I can pad the pot, knowing what the perfect amount of attenuation (-12 dB, -15 dB, etc.) is for my preferences.

When applying -15 dB of gain, there's only 2.49 bits lost of the 32 bits from my Chord Mojo 1, making it 29.5 bits. Should be completely inaudible. Someone please let me know if I'm missing something; any downsides. But so far, it sounds great and it's nice to be able to go to 11 safely but still with a lot of power!

You would put the padding resistors between the balance pot and selector switch. The resistors between the volume pot and balance pot must remain in the same position.

Thanks PB!
