A mini highpass/lowpass filter/buffer thing in a Gorva M45

Charlie Escher's  (@passinwind) design is a good place to start with that. https://github.com/Passinwind/PW3B-LPF/blob/main/V4 Schematics and BOMs.md

Nice plans! I have some of my own as well 😁

• My prunes and custard clone, the Plüm will go through some changes. I want to build my own version, slightly changing some stuff, e.g. trying out some LEDs instead of the diodes, etc. I think it could do with softer clipping, and I am a sucker for the sound of LEDs.
  Not that satisfied with the OD part of the original, and the drive pot's usable range is also quite small in my opinion. I found anything apart from between 2pm-4pm positions basically useless. That's going to the breadboard soon.
• I also need to test if a P&C can benefit from a BLEND, or if it's useless in that context. What can I say, I am a big BLEND fan, I think almost every pedal should have it 😁
• If I get the Fázz working, I am also looking to change some pots and R and C values in there to fine-tune it a bit to what I think it should sound like  E.g. the original Mastotron has a switch to cut off the whole bass or some of it - NOT IN MY HOUSE! Already removed that switch.
• Once that's done, I want to create an SMT version of it and slowly transition away from through-holes.

 

Speaking of SMTs, how do you do yours? Your Aotearoa looks so nice. Do you use a hot plate / hot air gun, or are you a solder iron wizard? I got a hot plate, but haven't got the chance to use it yet.

that’s interesting, for me the aggressive Wavefolding is what I like about that pedal - and my gain pot is pretty good for most of its range, which schematic did you use? Will it do the wah wah thing with a volume pot that Justin medal Johnson showed in the video with pedals and effects? 

in terms of blend…. The prunes and custard does have a blend already, and a switch to inject extra low end into the signal … what have you built if there’s no blend??!  

 

 

SMD stuff - I cheated and got jlcpcb to do the assembly for me! So much simpler and cost effective.

My laziness means ild like to try replacing the film caps with smd parts - but know it’s not quite so simple as that - and when I looked for some values the c0g part cost more than a box film cap would.

I will check it out, I’ve been looking at the fdeck one and the broughton one for inspiration so far.

I used the Fuzzdog one, Dirt Dessert. Drive below 2pm is quiet and useless, and between 3pm and 4pm it gets incredibly loud and overdriven very very quickly. I can wah it, yeah.

As blend, I assume you're referring to MIX? For me, that's not really a type of clean blend, as it's very much driven and impacted by the DRIVE value. The touch dynamic also changes greatly between low MIX and high MIX, it does not just change the signal balance/level.

The bass switch will be removed, as it will be always on.

I would be blending the clean bass signal into the driven bubbly mixed signal, but I'll breadboard this out to see if it makes any sense.

 

On the long run when I might actually be selling anything more than 1 pedal per 3 months, I am also planning to have JLC solder on at least the resistors, and maybe some caps (depending on cost), to speed up things. But I also want to give it a go myself first  SMT just seems like a different kind of fun.

Interesting, I think our pedals must sound different- I used the PedalPCB schematic. 
it depends on input signal but mine is distortion with gain below 12oclock and then gets increasingly wave folded as you turn it up. The mix for me lets me blend between wave folded madness and a cleaner signal - it’s gone through a preamp stage which has its own colour but running it with a clean blend in the loop of my hx stomp the effect isn’t much different at all. 
 

I had smd resistors, ceramic caps and the diodes in the diode ladder - saved ages soldering!
