Original 400RB vs. 400RB III...same with features?

[chandman1004]

I find myself wanting a 400rb so I can acheive the tone that I had at one time with an original 400rb. I have seen some 400RB III's for sale, does anyone know if they are the same amp plus features? Or are they a totally different design?

Largely the same.
If you want the exact same tone there are still early ones out there, if you look.

I had the first version with the plug in power cord . It never let me down , you could pound nails with it . And picked up an RB IV about thirty years later . To be honest , I liked the later version a little better .

I've owned an original RB and a MkIV. I liked both, but thought they sounded different. The pre shape filter buttons were very different than the variable contour and presence knobs. the Boost was also different. I couldn't quite get the MkIV to hit the rails like the original RB. I think the original and RBII are pretty similar, and the MkIII, and IV are a different amp.
