Thanky Sir! I wish I could say I did it with mine own little eyeballs...but I was peering through a monstrous "stero scope" during soldering.
Very nice! My process tech that does all of the handbuild prototypes at work would be impressed (and her skills are highly sought after, so that's a serious compliment)
...thought you would. I came close to setting up four 4-channel scopes so I'd have 16 channels total, but I finally figured out the problem to my functional test; I had some pattern expect data placed one vector too soon. Later, DJ
Love it! I have to make the post 10 chars so here are some more.
Hi Pliers - thanks for the feedback! DJ
Nice instructions. I use the uni-bit a lot.
WBA - thank YOU! I am gratified that this info (and Peter's input) was useful. DJ
Hi Jazzed - thanks again. Been doing the "gig" for 10 years and it's been an interesting ride. "Open mic"? Man, you're brave! DJ
Wow, excellent post! We use copper tape from time to time but get it from Grainger ($$$). I will definitely keep an eye out for that tape on my next Home Depot trip!
Dave, nice to hear you're involved with the community. Last time I played out was at an open mic before the turn of the century in Campbell. My muse still lives with easy classics piano, guitar ballads, and some composition.
Hi Eric - actually, the modern replacement from Dunlop (who now holds the product rights) charge upwards of $25 for the pot! Ouch! I've recently seen another manufacturer that offers a replacement for $15, so I may go that route. Tubes? Ahhhh, the absolute best amplification method for guitar. Depending on what type (naturally) there are current production sources that make reliable product. Svetlana was one until New Sensor bought the name rights and then there's JJ/Tesla that makes outstanding product. Later, DJ
Hi DJ, It was a long time ago so I don't remember whether it was a 1:1 reversal or if I had to fiddle to find an equivalent volume. The answer might also depend on the type of pot and the connections. I think this one was a simple center tap variable resistor. So one end was input, the other ground, with the dial controlling the wiper. And although a NOS Allen/Bradley pot might cost you $25 (kinda like finding replacement tubes), I suspect there are modern equivalents which would be a whole lot less.
Eric, Yeah if you put any audio gear in storage you should always leave all the pots at MAX. Then the dead-spot is never hit (well okay, but how often to you actually put a knob on MAX). Bean
...good tip. But wouldn't that have reversed the taper? DJ
At one point I had an old Pioneer Receiver where the main volume pot had sat so long at one spot that it didn't work well at other volumes near that spot. What I did was to desolder it and add jumper wires to reverse the polarity. So now what was previously maximum volume was now minimum volume and the "dead spot" wasn't a problem.
Hi Jazzed - thanks much! I'm a "weekend warrior" on the music team at church and alternate between guitar and bass. Do you play out? BOSS? Good stuff. My pedal board currently: Jen volume -> Tri-AC -> CE-5 -> DOD FX-70 -> DD-5 -> CabTone -> to the sanctuary sound board. I'm thinking about getting a different chorus to replace the CE-5; it's just not "lush" enough. Any suggestions? DJ
Nice blog entry. My wah pedal disappeared long ago. I do have several BOSS stomp boxes though. Do you play gigs in San Jose?
Lowes and its like 10 Mils or so . like half a fingernail thick . thickness . It comes in rolls . some with tar and some with none . It was like $30 . Peter
Peter - source and thickness? DJ
I use copper roof flashing for High current stuff. Peter
