i just did some research, and theres a $%load of laneys that look liek the protube.
From what i've found...
you have your basic jcm 800 kind with presence, 3 eq knobs, gain and volume.
you have your basic jcm 800 unit + reverb (not tube driven verb though)
pro tubes...
pro tube leads...
aor pro tubes
aors...
the protubes are basic single channel 2 inputs...
the AOR means that you have a footswitchable gain stage, basically hit a button and it adds another preamp tube in the circuit. Consider it a "boost channel" So you get your presence, 3 eq's, your regular pre/volume gain, and then your boosted pre/volume gain.
And another detail is some have FX loops and some dont, but again from what i've read, they have no dB controls on them, and can get pretty crackly.
From what i read, what i would do is get a laney AOR pro tube. No reverb, because i would never use it on a powerhouse like this. Also, you get the AOR booster thinger which is pretty damn key for getting higher gain. I wouldnt get the 30 watter because it doesnt have the option of the second set of preamp/volume knobs.
So that leaves a 50 watter and a 100 watter WITH aor circuit to choose from.
hope this helps somewhat.
