I recently got my first modded marshall, Ceriatone Molecular 50w. While diode clipping is great, without diodes engaded it sounds very good with sd-1 in front. I know that the amp is based on cameron atomica, so without diodes engaded it's probably similar to stock jcm800, never had one though. Great thing about this amp is that there is resonance control and negative feedback. With stock jcm800 you can't get that extra low end from the amp, i asume. I was wondering now if there's a reason to have 2204 while having molecular which is based on that amp and has more options or maybe tonally they have lot's of difference. Would be cool to get some insight about it from the users of these amps. Cheers.
