It looks nice, I like that switch

Thank you. I haven't found the time to finish the build, but hopefully this weekend i'll be able to try that nasty compressor!

Thank you, Bow & Error! I finished the veroboard yesterday, and used 12k and 33R ;) With the power supply changes, the 470µF are a bit tight to fit, but it still fit. I need to do all the wiring in the next days, I will let you know how it goes! By the way, about the transistors (Q2-Q7), which i...

Hello, I am building it, and I noticed that I am missing a couple resistors values in my resistor drawer. Quite often, I tend to use the closest value, but in this case, I think some values are crucial to the sound (and some others not so much), so I'd rather ask first :) - Can use a 12K instead of ...

Awesome, thank you so much, Kizzer!

Hello,
I am counting only 52 cuts (and I think that the cut in column 29/ row 18 is not needed)?

Awesome!
Thank you!
I see I had made a little mistake on my layout (the 10k resistor column 19, which is on the way of the 10µF to output).

... and the version with the power supply mods.
It's quite ugly, but hopefully accurate (?)
Please let me know if you find anything

Hi, I "frankentweaked" the layout to reflect some "Lacquer" mods : - R13, R44, R45 feature the modified values; - The VOLUME pot is added, as well as the 220nF cap (C22) going to lug2; - pulldown resistors added (R46, R48) - R47 added; - C23 added; It's a bit messy and not very e...

I compared the two schematics (level-loc 2.8 and level lacquer 3.7), and noticed 15 differences : - 3 values were changed (R13,R44, R45); - 12 components were added : R46 to 51, C22, C23, CPF1, CPF2, as well as D1 (the 5817 was removed, and replaced by a 4001 in a different place in the circuit) and...

@Bow & Error, thank you so much for your work! It's been a while i'm eyeballing over the top compressors like the Level-Loc, and I am going to build this one on veroboard! Your build looks awesome, too :) @Kizzer, thank you for the veroboard layout! A couple questions : Did the final (" Lev...

Hi, asbestosaurus,
It is not a big issue : I have built the pedal how you traced it previously, and I like a lot the sound I get from it
It might not be an accurate clone of the MI Blue Boy Deluxe, but it's a great sounding transparent OD!
Thank you for sharing your schematics and insight!

Thank you for your comprehensive answer, Manfred.

(by the way, I wired the pots correctly, and I am enjoying the pedal a lot : thank you for the schematic!)

also with fast(er) opamps like the 5532 it does pay to bypass the supply pins with a ceramic or poly 100n cap. Newb question : Out of curiosity, what does it do? Am I right assuming that it aims at getting a cleaner signal by removing DC noise? A bypass capacitor is a capacitor that shorts AC signa...

Thank you, Asbestosaurus! Duncan Tonestack calculator was very useful, and I'm sharing my findings : - The BigMuff tonestack is setup with values such as it is flat when not used (without the usual mid dip). You can get a nice tilt eq if you don't use the MID pot. - The MID pot is only cutting value...

Hello, I built it today : it's a very nice overdrive, with a very interesting EQ section. Thank you for sharing the schematic! I used a 5532 opamp, because i was aiming for a more hi-fi sound. Some knob action seems backwards (namely the CHARACTER and TILT pots), but I may have to check my wiring :)...

I am building it, and realized i don't have any more 22nF capacitor left. Am I right assuming that : - by using 33nF caps at the input & output, I will let more bass pass through, - and by using 15 or 18nF caps for the 2 others, I will change the cutoff point of the tilt eq and the low pass filt...

Thank you Asbestosaurus, your "humble suggestions" are really helpful

As an aside Gain calculation, if you (or other possible readers) aren't aware, is (R1/R2)+1. For an answer in dB, take the log in base 10 of the above result and multiply that by 20. To make the stage a unity gain buffer, short R1 and remove R2 completely. So, am I right assuming that with R1 = 47k...
