Muroidea Bass Boost Mod

[mckillacuddy]

I just threw it in the existing circuit on a whim, haven’t tested it extensively at all but it works and sounds fine. Gonna do some more poking around when I’m off work today.

I’m very curious. Datasheet shows 1.8-5.5v supply

Well I should probably take it out then it was just something I had around, I didn’t really look.

Sounds like it's on the verge of melting...

Sweet.

Nothing really happened lol. No smell or pops

I guess I gotta build another rat

Just keep in mind you're letting more bass through at the gain stage, meaning you get a very flubby low end on a pedal that is already known to fuzz/fart out at high gain settings. If you want more bass but keep the response, you'd have to add an EQ stage after clipping.

This can be mitigated by scaling the filter in the feedback loop.

560r and 4u7 can become 5.6k and 470nf, keeping the filter the same but lowering the gain. I actually do this to both filters and then use a 250k gain pot. All the “way too much” of the original, and now a low gain setting.

Yeah that's just not turning up the gain with extra steps...

have you tried chuck's contour mod? I prefer it to messing with those filters if you wanna bring in more lows, or messing with the 3.3n/1.5k tone stack

I just built the Frajeelay yesterday where the weight control is basically this, but with a C1K pot. Cool and useful mod!

I was curious how the 1K pot compares to Chuck's 5K pot, so here's a comparison within a simulation of the Frajeelay circuit. Top is 1K, bottom is 5K. So, smoother sweep with the 1K, but at minimum it will add more bass than the 5K pot.
