Re: Shure - Level Loc Compressor
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!

Re: Shure - Level Loc 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...

Re: Shure - Level Loc Compressor
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 ...

Re: Shure - Level Loc Compressor
Hello,
I am counting only 52 cuts (and I think that the cut in column 29/ row 18 is not needed)?

Re: Shure - Level Loc Compressor
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).

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

Re: Shure - Level Loc Compressor
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...

Re: Shure - Level Loc Compressor
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...

Re: Shure - Level Loc Compressor
@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...

Re: M.I. Audio - Blue Boy Deluxe [traced]
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!

Re: M.I. Audio Blue Boy Deluxe [traced]
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...

Re: M.I. Audio Blue Boy Deluxe [traced]
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...

Re: M.I. Audio Blue Boy Deluxe [traced]
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 :)...

Re: M.I. Audio Blue Boy Deluxe [traced]
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...

Re: M.I. Audio Blue Boy Deluxe [traced] [traced]
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...
