nice, where do you get those big knobs from?

that's what I thought, would it be a problem that I followed the GGG schem but am using the madbean wiring diagram? I'll eventually be putting it on a mudbunny PCB anyway.
If it still doesn't work after I've redone the wiring I'll post pics.

Just had a thought, at this stage I'm just wanting to do some component swapping and modding, so could I just hook up input and output with 9v wired in and forget the switch and LED for now just for simplicity, so I'd have an always on circuit?

I have breadboarded the circuit but am getting just a buzzing sound when the effect is both on and disengaged, LED lights up, but nothing but a loud hum. This is the 2nd time I've breadboarded the circuit and I'm almost certain I've done it right, does this sound like a wiring issue?

Welcome! A great choice I must say
Green film caps will work perfectly fine. People claim to hear differences in using different caps, I've haven't tried yet but nothing that's really gonna change the uniqueness of the circuit.

Here's a thread where I've done a diagram for the tone stack lift. I made a small mistake but if you read the post I noted the corrections. There's also info for a mids knob in there too if your interested.

I understand what your saying with the tonestack switch but I can't think of anyway off the top of my head that you could do all three on one switch. There are DPDT ON/ON/ON switches but they still combine the middle with either top lugs or bottom lugs so its not 3 independent choices. Here's what I'm saying..http://3.bp.blogspot.com/_hWtqqQxBsDs/Sctkoll7-tI/AAAAAAAAAFY/V7jHQnasuFA/s400/DPDT_switches.jpg I can think of a way using 2 switches, but honestly I recommend the mids knob as a great mod. It will add tons of versatility by letting you adjust from the scooped mids to flat mids to boosted mids! Along with jumpering the emitter resistors of Q1-Q3 you'll have a tone/gain beast!

I thought about the mid knob but I really only want two or three subtle differences, a mid knob is just gonna be more tweaking and less playing for me, I might just go with green russian specs and then a different setting with the toggle switch which has a less pronounced mid scoop. I've been playing round with the tonestack calculator program with this anway so will probably just find my two favourite sound before I commit to PCB

Hi am building a mudbunny and have a few questions while I'm waiting for the PCB
The partlist recommends film capacitors for most of the caps in this build, all I could get from the local supply store was green caps like this
but I figured they would be okay didn't have any of the plastic rectangular film ones I see in most Big Muff builds.

Also am putting in a tone bypass switch (like the tone wicker on the new big muffs)
and was also wanting to be able to switch between green russian and triangle and possibly rams head tonestack specs. Since the only differences in the tone stack are two resistor values, could I just use a switch with two sets of 3 terminals to switch between the 3 different modes (russian, tri & rams head)
What's that like a DP3T? Sorry for noobness, I'm sure there's a simpler way than how I'm describing it.
