I would have Nik build a chupa to molecular specs so you have the added gain, 3 way bright switch and feel switch that are adjustable. I’d have him build it with no iron and install some MM transformers on it.
The chupa spec is more dirty, gainier, darker, and more compressed. The gain just sounds nasty in a good way. The molecular is more classic modded, hot rodded Marshall, that is cleaner, brighter and more open.
