Very happy with the 75. I bought it for the use it's intended for, which is practice at low to moderate volumes in a home setting. I use an iPhone 6Plus to control it and practice while watching TV in my family room. Wife acceptance factor is much higher than when I had my JVM410/1960A, or even the V3M/Orange 112 pair out there. Unobtrusive, functional device that met my expectations entirely. If I want to get loud, I hit my tube amps.
