I was rockin' my Trinity Tweed Dlx not more than an hour ago, I love the way it sounds. Just guitar into the amplifier produces some seriously satisfying tones. I had an enjoyable and very easy time building it due to some great prints, specs and manual. I like the components supplied and was very pleased with the support on any questions I had of Stephen. I'd do it again if I had more time to spare these days. I would urge anyone with even an inkling to give it a try, building an amp, because it looked intimidating but it really wasn't when you take it step by step. As for the voltages, just don't lick anything or plug it in while working on it and you'll be fine. Another important thing is having the proper tools, mainly the soldering iron, it makes things easier and quick.
