For as long as I can remember I’ve been taking electronics apart to see how they function . I have no real Ideas way ? Maybe it’s in the family blood. As time moved forward I got better and it didn’t take long before i was fixing more complicated problems . I focused on fixing guitar amps ,synthesizers and radios because I could buy them broken for repair and use them for trading or recording .Great thing is when equipment fails, which seems to be a lot when using vintage, I can simply do all the repair work myself. I’ve spent many years building variations of studios in my home and have utilized these skills in wiring and electronics to build my dream studio. I don’t think any of these rare, and some times expensive, recording equipment are necessary, but on my song production it’s the sound quality these pieces add that my ears hear which makes all the difference. To be honest though, I’ve done really great work using bare bones setups too. I always look at things as art- if you have all the paint colors, you don’t need to mix them up but sometimes you find something great in the minimal. It’s all about perspective.
