Greg Germino is widely accepted as one of the top Marshall style amp builders to ever do it. This Classic 45 is no exception - the only way to surpass this is to bite the bullet and pay $12k for an original JTM. With nothing but the best components and custom spec transformers, this amp has been tuned to perfection - and even features a PPIV Master Volume, located at the rear of the amp! So the volume should never be an excuse with this one. The amp is in great shape, with only minor signs of previous wear. Also, there is no impedance selector on the back, so you can best assume it's hard-wired for 16ohms, like the original Marshalls.
