The 2203/4 is a great amp, and is responsible for some of the best tones in Rock. However it is an amp which most of the time is used in conjunction with some sort of transistorised foot pedal - either to "boost" or increase the gain of the amp - or to attempt to increase volume and gain for solos (which does not work particularly well in my experience if the amp is already saturating....) A better idea would be to produce a similar amp, but with a separate lead channel. The JVM410 is almost that amp - but has small but significant differences in voicing (i.e. it is not as bright) and power section (which is tighter and less prone to Power-Amp distortion). Both these things are easily fixed with quite minor mods (as I have done) - and the result is an amp which can sound and feel like a 2203, but with a lot more versatility and options - and all this can be achieved without the need for external transistorised pedals! Of course what I am describing is a modified amp, not a stock factory one - so rather than see a 2203/4 re-issue (with all the limitations the originals had) - I would rather see what I would call a "JVM800" - which is basically what I have with my modded amp!
