My opinion (I'm far from an expert but I have successfully designed and built a few from scratch while chasing a particular tone.):
In order of what I think is important:
Number of turns (which along with other stuff leads you to inductance), magnetic field strength, shape of magnetic field...
I got a squier tele. When I was traveling, I took the neck off and put it in my suitcase. As long as you're cool on tightening, there shouldn't be a problem with stripping. I put inserts in one before that, but it was more trouble than it was worth.
Sorry no photos right now.
I have 2 teles:
1) cheapest squier affinity tele and a
2) nice alder body by Bunker with warmoth birdseye maple/maple neck partscaster.
The squier is much louder and midrangey. The partscaster is quieter and much more trebly (and heavier).
I picked the...
Just don't use a square wave. I foolishly tried breaking in a cheap set and almost burned them up. I forgot about the power in a square wave being greater than a sine wave. D'oh. Luckily I checked them just when they were getting too warm.
Pulling could well be right, or fretting just a bit harder.
Sounding "perfectly in tune" is actually a bit off from the actual defined major or minor third, or any other interval except for the octave.. That's because most of us use an "equal tempered" 12 tone scale which causes things to be a...
I've been watching DRRI videos on youtube.
Psionic Audio has a ton of good videos on this amp, showing innards and telling you what to look for.
If you're not already a tube tech I wouldn't start learning on this amp. There are some gotchas in the PCB design, but easier to work on than a lot of...
