Re: Diy amp kit - for a beginner
I would recommend reading some threads over at ax84.com and ampgarage.com, and using the info from there to get a better idea of what to do.
Besides that, I would recommend starting out with smaller, easier projects. Things like swapping out guitar pickups/pots/caps, modding and/or building a pedal, or maybe even modding an existing amp. This is basically what I've been doing for the past year. I've swapped out pickups is a few of my guitars, some of them several times, and up graded the pots too. I've also modded my Marshall JVM (still have a bad solder joint to track down, my bad), modded both my MXR Wylde Overdrive pedals to run 18 volts, and have the parts to mod one of my wah pedals when I get the time.
All of it has been a learning experience for me, plus it has helped me get better at soldering. And looking back, I'm glad I did all of this before building an amp, because the amp I want to build is a Trainwreck Express, which is a design that is very finicky about how the components are layed out and the leade dress of the wires. But it's first on my list, so I'm determined to do it. The kit I've been looking at for it can be found over at triodeelectronics.com.
