The JTM 30 does the best clean fender sound around, the dirty channel is a bit farther.
The design is more for Iceland than Aus, the horizontal power tubes vent into circuit board and that vents.... Well nowhere.
Apparently the solder they used in making this was 'bad' so dry joints are not uncommon.
Then there are the spade joints on the standby switch, and the cheap jacks that tend to corrode.
BUT the sound!!!!!!
And yes I had an Alpha Sprint, there's nothing like having to hold up peak hour traffic while you roll the fuses so the idle circuit works LOL
