Hello I have a small question concerning the types of potentiometers referenced on your layouts. when it's noted B, does that mean linear, and similarly for A, does it mean logarithmic? the reason is that standards are not the same depending on the country, and A / B can be reversed! Of course C is antilog, which seems obvious to me! Thanks
The 1k is right there B13-16, it has a link leading down to row I, then another link from I to ground? It’s kinda hard to see since it’s transparent & over a cut?
push 2 needs to move to row A. I built this up last night but it didn’t fire up right away. I’m working now then off to Kurt Elling concert. I saw Charlie Hunter last month. If you’re in Europe you can see them together later this year. I’ll check back in tomorrow on this circuit and the concert.
If you are looking at the lugs on the bottom of a 3PDT stomp switch, and they are facing side to side, not top to bottom, they are numbered like this: _1_4_7 _2_5_8 _3_6_9
Sorry I should've been more specific. The dpdt. I have a layout for the stomp switch. Thanks though! Appreciate it. Also, after looking at the layout and using my brain, I figured out the switch pinout... I think. I got it working anyways! Haha Just started building a couple months ago and already have a shelf full of circuits. Just never sure of the pinout numbering on these. I usually just trial and error.
DPDT is just the first six lugs. Most two-position switches have a center lug that swaps back and forth between the lugs above it and below it to make or break connections. Build enough and eventually this stuff will all become second nature.
When I first started I had cheat-sheets hanging above my work station with lug numbering for pots and switches, as well as conversion charts for pF to nF to uF capacitor values...
Hadn’t heard of this one. Sound demos sound rad.

Yup, A-log, B-linear, C-reverse log
DeleteDon’t forget about the confusing W taper. First half of the pot functions as a reverse log(C) pot, second half functions as a regular log(A) pot?
Deletethanks!

ReplyDeleteif im reading the schematic correct :
ReplyDeletepush3-->d1
q3 e -->vcc
q3 c needs 1k to ground

ReplyDeletethat 1k needs to go to q4 not q8 ( b16 is q8)
Deletewhat a confusing layout lol wtf
Deletei think im wrong cause that link is ground again like i said so confusing this one lol
DeleteQ4 & 8 emitters go to ground tho? I agree, it’s a tricky one!
DeleteThe layout is updated since there was a missing resistor across the base and collector at Q8.

ReplyDeleteQ4 Missing 1k collector resistor, it’ll fit nicely G-J16. I wish I was home to test it!
ReplyDeleteTag it! Works with changes noted. Sick and disgusting, just like the demos. Thanks Anders!
DeleteI’ll box this one up, for sure! And: Kurt Elling! What a show, SOPAC, S.Orange, NJ!
DeleteThanks guys!
DeleteJust updated the layout and tagged it,
lol after "altering" the original board I cut and made I can also confirm these fixes work. and it sounds raw and nasty in a great way.
ReplyDeleteHello fuzzhead!
ReplyDeleteI have made a layout of the latest retroflect schematic, how can I send it to you?
Hey, just wondering what numbering layout you use for these switches. Top left corner is 1, then down 2, or right 2?
