Working on gear
Posted in Geekery, Main on January 25th, 2008 by MarkusIt’s a Friday night, rainy and cold. Glenn and Therese invited me to go out with them, go to a bar or two and maybe sing karaoke, but instead I decided to chill out at home and get a leg up on a project or two.
I have this Alesis guitar amp, a Spitfire 15, which gives away the fact that it isn’t so new any more. Alesis changed the name of this line to Wildfire some time ago.
Still, the amp isn’t really all that old. If it were, it wouldn’t have the damned plastic quarter-inch jacks that I have learned to hate so heartily.
It’s a good amp, all in all, but the plastic threads on the input jack got stripped and would no longer hold the metal nut. (Metal on plastic, in a place that can be subject to repeated stress. Brilliant. But I’m venting.)
I’ve had it apart several times, to investigate and then to patch. The input jack is soldered in three places onto a PCB. I finally found an outfit that carries such a jack (thank you, Studio Sound Electronics), and took a chance, going mostly by the picture and also somewhat by the description (which did not say “Alesis”, but was still encouraging). They tack on an extra buck-fifty, IIRC, unless you order at least five bucks’ worth of stuff, and this was $4.95. Of course. I thought about ordering two, but instead I grabbed a cheap set of allen keys. I can’t find the two or three I must have around here that would fit the bridge of my Squier ’57, and the string height has been bugging me. I could have just paid the little bit of extra shipping and spent less money, but for about two-fifty I got something else useful, until I lose it/them as well.
The operation on the amp commenced this evening, and it was a pain in the ass. I do not have a solder sucker, so getting this three-legged monster out of the PCB was not fun. The old jack had started disintegrating, however, which helped me. By first taking it to pieces, I was able to remove it one leg at a time (one of the legs being amazingly, almost magically stubborn). Then I had to engineer a way to clear the holes. Then I lost the new jack, and spent a few minutes searching, cussing, and searching some more. It was way more complicated than it should have been, as such things usually are, and several of my fingers and the soldering iron made very brief contact, but I managed not to burn myself, and at last I got it done.
Naturally I pulled out my guitar to test it, and my eyes fell on the allen keys.
At first I thought none were going to fit, but happily I was wrong, and soon I had my strings nice and low. A long story on that, but this is very sweet–only now I’m too tired to play, having stayed up way too late this morning, and so I’m half-asleep and it’s only a little after ten-thirty.
I set my guitar’s intonation a few days ago, which was a huge improvement. That intonation thing is really all it’s cracked up to be. I might need to double-check it now, maybe tweak the action a little more–it just might need a small truss rod adjustment. But not tonight. At least it’s much closer to dialed-in than it was before. It’s a sweet-playing guitar now. Best of all, I can plug in to my amp without the jack falling inside.
Note to self: thread the patch cord through the handle. It’s a great strain relief. Just sayin’.
