5K VOL Pot in Red Llama OK???

[csmatt45]

I'm building the red llama and have a brand new 5K log. I'm assuming this should be OK, but was wondering what would be different? Just slightly less output, and less bassy?

BTW, Mark H. if you answer this, I'm thanking you in advance. I've learned alot from your detailed answers. I also was able to find the UB CMOS at Frye's this-morning, but I didn't pick up a 10k log!

The math of it all is still fuzzy though....babysteps...

BTW#2 Does using a CMOS mean this constitutes calling the Llama a "Digital" pedal?

best,

Matt

The 4049 is a LOGIC chip....I guess you call it logical distortion...

I don't have that schematic, but if it uses the pot connected between an inverter output and ground without an additional series resistor, it will probably make little to no difference. If there is some series resistance, you can try knocking that in half too in order to keep the values scaled by the same amount.

In this case a chip that can be used as either an analog or a digital building block is being used in the analog domain. When you introduce a DC feedback path around the inverter, it starts acting like an inverting opamp with very low headroom. There are also CMOS opamps like the TLC2272 which are totally analog.
