Exceedingly good changes with the addition of the 22, but here are some suggestions for improvement, new products in the line (hey forum users: chime in; maybe Fender reads this!)

1. Add a 2x12 combo for at least the 60. Maybe even a 4x10 (voiced like a SuperReverb).

2. The Marshall JVM410 (and 210 and 205) have the ability to run the preamp in standby. The power section is just turned to "heater" mode. The whole preamp runs, including parallel send/return, serial send/return, and emulated line out. The Supersonic's should have that feature. It's great for silent practice and for recording direct without sound in the room. And it saves the output tubes.

Question: can this be done partially now by using preamp (line) out to drive recording or headphone equipment, and then plugging a null jack into Preamp IN so that there's no power output? Does doing that turn the premp off so nothing comes out of "preamp out?" Only partial because the power tubes are still on, just not working hard or at all.

3. Implement MIDI control similar to Marshall: allow midi program change to select the same things the footswitch does: normal/fat (vibrolux/bassman); burn, reverb, loop. Since the footswitch cable is special, it can't generally be used from things like TC G-System. This is an even better way (imho) to control amp channels.

A lot of good ideas;
On remark, the valve shall not be heated for nothing. In fact when a filament is heated, there is a space charge around without "electron beam", this space charge protects the filament and the cathode. Nevertheless there is "probability" to poisoned the filament and/or kathode by other metals positve ions even gaz in the valves. It is worse for "cold" emission for instance for valve amps without standby.
(The good habit I have had with my Marshall in '80s is to heat up half an hour before playing, to put in standby in case of less than 1 hour breack and put in standby after a playing to cool down a little bit before shut down avoiding cold emission. It a compromise between number heat-ups and time of heated).

I agree, standby is an important function. For both my Marshall and Fender Tube Amps, I always turn on to standby for at least 10 minutes; breaks go to standby, then standby for at least 10 minutes before powering down. Prolongs tube life not to cold start any of them.
