I play the Metroplex and all I can say that this amp kicks ass. You have basically 3 modes: 66/68/Mod and an internal booster. You can read up the specs, I won't go into that, but what makes this amp outstanding is:
- The Master Volume is very good. I can't explain it technically but it just works. At lower volumes the sound is still very complex and only the silent version of the cranked amp. A very big plus. Its just that good, This alone is worth a lot, you def. won't need an attenuator with this amp.
- The Hot Rodded Super Lead 68era and beyond is the strength of the amp. This raw sticky upper mid pronounced sound, not overly compressed but with lots of harmonics. What a joy to play if one can appreciate it and has the right technique. With th booster you get liquid lead sounds of it, think 80s hard rock
- The loop is very transparent
- the build quality, the quality of components, high quality pots, and so on, the labouring to recreate THE brown Marshall sound, its just a very well made amp which you can see, feel and hear.
If you want this complex, rich, natural and raw uncompressed Marshall sound we all love from the famous records, this is the amp to go. Ist not hyped with strong bass frequencies, it just sits well in the mix, its all about the complex mids. Go for it I would say.
Here is a good representation of the MOD mode of the amp. The first half without the boost engaged sounds good, don't you think? With Boost on 10 its too much for my taste
