No holds barred, spare no expense, use your imagination. Here's what I was thinking about today. 300 watt all tube power section with built in speaker-level di. Tube preamp with sweepable high pass and low pass filters, 4 band fully parametric eq, all of which are servo controlled and Bluetooth enabled, allowing them to be controlled through a mobile app. A simple, one button ts foot switch to switch between 2 user-defined settings (using the servos of course). Shareable presets in the mobile app, and factory presets of famous amps. The digital portion of this amp only works the defeatable servos. If it dies, the amp will still work fine as a fully analog design. Is that really to much to ask? Ha! I wonder how much something like this would cost? What's your dream amp?
