The Pot dilemma

My daughter knows the fella who did the panorama video for Sweet Talk.

I thought this might be interesting and as I already had a spice model of a tube screamer that I play with I decided to plot the differences between the options. Keep in mind this is a TS808 with the gain and tone in the middle of their sweep and then the level control turned from 0%-25%-50%-75% and 100% of the rotation.

Thanks for the visual. I ended up rolling with the b100k w/o modification and it seems to be just fine.

I don't know how to interpret swyse's scope's findings.

I see the colour bands bunch up differently between the A and B tapers, but the A100k and A500k are nearly identical in terms of spacing between coloured lines, at 10Hz — -10dB, -20dB, -30dB and -40dB.


So I guess if I had to sub out A100k for either A500k or B100k I'd choose the A500k.

I'd use the pot in the BOM.
