I'm a techie by nature, so when I was first introduced to the dilema of solid state vs. tube amps, I simply built a simple patch cord box with a foot switch that allows me to choose between my antique Fender tube amp and my mega modified tranny amp. Both amps play into an old Fender XFL-1000 Speaker cabinet with 4-12 inchers. I get the warmth I like for country and blues from the tubes, while tecno and metal sound great on the tranny. Just in case there are any crazy surfers left over from the 60's, you might remember the old double spring "Beautiful Woman" reverb units. I also have it incorporated into either amp by way of another foot switch. A third foot switch controls the introduction of a second spring unit for a very special exagerated delay. the final foot switch conrols a simple solenoid from a doorbell that is mounted in such a way that it "kicks" the spring unit for that "splashing" sound. All equipment I have is under continous modification and I would not be without either setup. Let's hear from the rest of you techies about your projects.
