I didn’t fully think through “Blammo!”…

Just make sure that the fan motor does not produce any sparks!

These two cover my experiences also—both builds were for friends. The Bottlehead projects are really good sounding; I was almost shocked at how good their phono preamp is. (And he used to make a small guitar amp that I am truly sad I didn’t get when they were available.) My current headphone amp...

The LA-1A is almost impossibly quiet, and I think the parallel operation is a definite part of that. Many years ago, I built a phono preamp, for low output moving coils, that used two gain stages before the output stage, all 6DJ8 variations. This was back when you could actually buy, for not too...

When you replace the resistors, leave a gap between the board and the resistor body. (I use a popsicle stick as a spacer, then pull it out.) This let’s the resistor dissipate more heat, protecting it and the board.

i use alligator clips also, but if I need to poke around anything with more than ~40 volts running through it, I use probes with insulation until the point, just to keep from hitting things and creating shorts.

As are these—or you can do a few layers of heat shrink over an existing pset of probes.

I think @Robert usually references the original parts, if they are still available. With the original pedals, it really depends on who the maker was—very often, it's whatever was be least expensive, even if it's just a matter of pennies. Certainly with something like the wild number of Muff...

When you play clean, can you really push the volume through it? If it can play loud while clean, I’d recommend trying just your guitar, amp, and a single drive or distortion peddle, as a test. I‘ve built amps, but can’t pretend to really understand what the electrons are up to. But it seems...

I’ve built a few “dumb” loop switchers, and used 1x 2 inch aluminum tubing as a housing. I cut one of the 2 inch sides so that only 1/4 inch is left on each side, and screw in a thin plate of aluminum on the bottom, with folds at each end to close it up. (There is a slight notch cut into the 1/4...

Not that I’m opposed to building several varieties of switchers (or anything else, it would seem), but knowing what some of the other upcoming options might be would certainly be great. I know it’s still early in the process, and your starting this thread as an organizing one for the possible...

My email from Antique Electronic Supply showed these, and I suddenly knew just what pedals have been waiting for them...

How about the next size up (chicken head)?

I always do a thin tinning coat on both wires, then position them so they’re as tight as possible against each other and wave the soldering iron in the general vicinity. I just saw those Omnifixo clamps for the first time this morning—they look really nice.

The other approach to this is to cut the screw shorter. For screws up to #8, these work very well. (And on most “included” screws, which are usually shit steel, the larger sizes cut fine too.)...

Chop Shop has been mentioned, and I also really like Champ Stamp, both at 18v. (Both are also transistor based boosts, which I’ve come to generally prefer.) Chop Shop doesn’t have any EQ controls, but is dialed in to somehow work with all my guitars anyway.

Same here, Pot and Kettle is my only build of that genotype. It’s one of a handful of favorite boosts though.

At times I really love what the sag does. It sounds convincingly like an amp that’s struggling to get enough power to me—the bass begins to weaken, the dynamics squash in, there’s a bit of lag sometimes with peaks that feel very organic to me. And that’s with me typically running the pedal at 18v…

I’ve plugged various Engineer pliers in several threads, and gotta do it again. Next time you wear out a pair of pliers, or maybe you decide its a style you use a lot and would like a bigger or smaller version— check out what Engineer makes, get over the cost, and treat yourself. Vampire is from...

The charge pump data sheet for the pump specified maxes out at 13 v input. There are several other pin compatible pumps, but I don’t think any work at that high a voltage; with luck you’ll get a more definitive answer soon from a forum member that really knows this stuff. Not as convenient, but...
