I love Marshalls, but the one thing that's bugged me about them is that their build quality doesn't seem to be improving very much. One impressive thing that Mesa has done is that they've managed to become innovative while maintaining very high quality builds. Mesas are a different beast, of course, and I don't particularly like their distorted tones, but they're built very solidly. It seems like there's been a response to the poor Marshall build quality. A ton of small amp clone companies have sprung up, all based on classic Marshall designs. Ceriatone, Metropolis, Egnater, etc. It makes me wonder what modern Marshalls would sound like if they had better build qualities.
