    pedal output and "line level" output - difference in output impedance

    I think I posted some of this before - but I'm still confused about "output" stages in pedals. I assume most pedals are "designed" to work with guitar inputs on amps. So the amp typically has a high impedance 1meg etc right? But if you want to plug a pedal into a "line level" (either +4dBu...

    Harmonic Tremolo - switch to "normal"?

    So a harmonic tremolo has a High Pass and Low Pass section. Each with a LDR (not sown in circuit). Can you get a "normal" tremolo sound by only using one of the paths and opening up the filter? Something like below where you switch C7 and C5 so they are either "off" (as shown = normal...

    Not too much smt experience - working on a driver board for some RD. First Question I have a 80 pin BGA array package that I *have* to use, with all other thru hole components. Somebody mentioned I need a "tooling rail". ? Cant figure out what that means. Is that just a boarder around the...

    Anyone tried the "toner transfer" method for pedal artwork? Looking for recommendations and success stores on what brand of paper etc My -pedals have a thin (0.030") aluminum 2.1"x2.1" plate where all the graphics are - so Im not heating a large area and I would think this method would have at...

    Tayda or Alpha pots?

    Are the Tayda standard 16mm same as or as good as the Alpha? Anyone have issues with either? Just curious - they look the same - likely from the same factory.

    PCB design: surface mount layout help (tracks)

    So I'm doing a surface mount board for the first time. I've done a few dozen though hole projects, etc. It's going to require a different strategy I guess! In my through hole designs it sure is nice to have the option of FRONT or BACK (2 sided board) due to the nature of "through holes"...

    what software is the pedalPCB forum?

    I know way off topic, but the forum has a really nice clean look to it. Is it custom or opensource or ??? I used to do websites but that was AGES ago. I'm probably pretty far behind the times....

    BC560C source

    Need a bunch of BC560C (not B) for a project(s). Mouser/Digikey are phased out (they have the BC550C) and tayda has the BC560B. Any sources that are reliable? Looking for about 40-50 parts. There's China - are these likely counterfits or too cheap to bother...

    Dark Rift Delay 1uF caps - ceramic?

    There are a boatload of 1uF coupling caps in the Dark Rift Delay - why the small package footprint? It pretty much dictates ceramic - which I have but.... Is it better to try to cram a 1uF film in there? Or doesn't it matter?

    checking for fake OPA2134?

    I think ChuckDBones posted awhile back that he had spotted some fake OPA2134 by measuring current - is this the geneal method to check for fakes?

    Enclosures from Tayda?

    I usually buy my 1590B's from LoveMySwitches - but they're not in stock and I'm placing a Tayda order anyway. Anyone have good (or bad) things to say about Tayda encolsures? I only build for myself and don't need new car type paint and finish - but something that looks decent and doesn't...

    Fuchsia Fuzz Treble Pot A25K

    Tayda doesn't stock A25k (the treble) pots - B25k or A20k - yes. Which is better to swap or do you really need the A25k? SmallBeard does - but ordering 1 pot is going to nail me for shipping

    TAYDA for OP2134

    Tayda has 2134s for $3.5 - a buck cheaper than Mouser but I don't get hit with Mousers $9 shipping. Anyone bought these from Tayda or have opinion on reputability for these types of components? No dis intended - I've had GREAT luck with them but the market is flooded with fake JFETS, OP AMPS...

    Recent score of several hundred NOS 2N2222A, some gold leads. Not a burning question - but any reason not to use them over 2n3904? And they just look cooler....

    using NPN instead of PNP in fuzz

    So looking at all the cool fuzz projects and a lot are PNP - not all but a lot. Given that I've recently inherited a bunch of NOS NPN germaniums I was wondering.... Anything wrong with - aside from not being correct vintage wise :oops: - using NPN and jumping / leaving out the charge pump...
