whats the difference in a white knob model t and a red knob other than the mid select?
anyone know im curious to know
-
There are several differences.
First, the mid select. the way it is wired, the mid boost is always on. The control simply determines how much mid boost is present. But turning it all the way down does not turn the mid boost off.
The master volume is wired such that it maxes out at about 8, and turning it up beyohnd 8 results in less output. I have no idea why.
The tone stack is different. The first generation is a classic guitar amp tone stack, with the flattest position being with the tone controls at zero. All boost, no cut. The second generation has "hi-fi" tone controls, with the flattest response being at 5. Boost and cut, except fot the midrange control, as noted above.
That's my understanding, anyway.

thanks issac i just always thought it was you got a mid select with the red knob ive been hopeing i could get my hands on a white knob and put um both side by side and see waht all the differences where.
-
just for the sake of asking would one be able to take and make a red knob a white knob by removing a component or something?
and if so how would one go about doing this?

In my opinion, the "white knob" Model T (the centers are actually silver) is the superior amplifier. I don't know why anyone would want to make on into a second generation "red knob" Model T, but opinions differ.
It is possible to convert one to the other, of course, but it's a bit more complicated than just "removing a component or something". At one time, there was a lengthy series on how to convert a second generation Model T to a first generation T, but I don't know that it's still accessible.

thanks dude you rock your like the Dalai lama of sunn amperage. :mrgreen:

Both generations have their merits. A friend of mine has the 2nd gen, and really digs it compared to the first gen. I'd suggest investing in a first gen when you can. Overkill, maybe, but it's a sound investment. :)

My own T is a transition model. Silver knobs, mid boost switch, and, I think, the original tone controls.
I made a couple of mods. I clipped the white/blue wire connected to the master volume control (which makes the volume max out at 8 rather than 10) and changed the mid boost so that it is off at 0. Those are simple changes. I think this makes mine pretty much the same as a first generation T, but with a switchable mid frequency control.
