1 JPK 3 years ago This is one of the least known Fender Amps - and there is not a lot of internet info on - so I thought I would share my experience with it.My main amp for gigging and studio the last few years has been the 63 Vibroverb Reissue, which has a unique sounding Trem and Verb compared to other Fenders - plus gives a nice growl. It was a tough call - but I went ahead and sold it to free up funds - and picked up a 90s Dual Professional in excellent condition.After the success of the reissue guitars and amps - Zinky wanted to create some new models that would renew their reputation on the high end w pros. They made the Tone Master, Vibroking, Rumble Bass and the Dual Professional. They were Point to Point and made one at a time in Lake Oswego, Oregon - according to the manual.100 watts 2 x 12 Celestion Vintage 30's 2 switchable Volume controls w fat switch 3 knob Tremolo Direct coupled Oscillator TremI have had it for about a month now and it is has lived up to what I had hoped for - and more. I am seeing this as my Holy Grail amp.Yes it's a heavy 76 pounds - but it is super quiet and there is a 3D sound to it at all levels. Trem and verb are superb. A bonus is that it breaks up earlier than I had been led to believe - works well with Supertrons, Gibson Humbuckers and Fender single coils so far. Recommended.
