It’s all grins and giggles until it isn’t. When I was a kid I “may or may not” have inadvertently blown up an amp too along the way. But more case in point, My own case in point; about three years ago, I bought a nearly new used Sandberg California California II TM5 Bass. Absolutely loved it and still do. Since I have done my own set ups for 5 decades +
i thought I’d make a small action adjustment. Started turning screws and and I thought nothing had happened. But suddenly I realized I changed one of the heights screws and the spacing screws. It took me a minute to figure out what I
Had done wrong. And to repair my screw up and get it back to square one.
Moral of the story is: with any piece of gear that is new or you were unfamiliar with, take the time to do a bit of research before you mess things up. A prime example would be the truss rod screws on a Pedulla bass which operate opposite to the de facto industry standard. Many owners and even experienced Luthiers have been fooled by them and done serious expensive damage. $$$ !
But the REAL point is, if you’re going to work on your own stuff, WHETHER YOUR CAR OR YOUR BASS or PLUMBING IN THE HOUSE .learn how to do it correctly. in some cases like tube amplifiers and modern DL amps with high voltage you can literally kill yourself if you don’t know what you’re doing. So it follows that if you’re willing to spend money, pick a number any number, take a minute DO YOUR RESEARCH FIRST. You should know your uses and needs, and the products that are available at your price point. I typically think in terms of how much can I afford to lose on this. But since i can be OCD about some of this stuff, I believe doing your homework is part of the job. I research the crap out of things. The more something is going to cost me, the more research I do. It also makes for far fewer expensive disappointments when buying.
