The BE50 is my Marshall-like amp that I use these days. True, it's not an exact Marshall sound, but it's very pleasant in its own way. I really like the BE and HBE high gain tones, as it's Dave's version of a high gain Plexi. I had Dave add the Thump option of the JJ100/Slax to my amp (he put a push/pull knob on it). I do prefer the Thump tone of the JJ/Slax, although both are good. However, the other mod he added is a lot more interesting. I originally asked him to add the C45 switch. He did, but it only seemed to add some punch or percussion to the tone. It wasn't an improvement over the regular sound. I asked him to check it and it was correct, but he added an HV (high voltage) switch, which in the left position, it adds the voicing (higher treble and frequencies) of the JEL50. This is very cool because it sounds very close to a high gain JCM800 with this switch engaged. I asked Dave about getting an IRJ and running into the loop and he said there was no need to buy it, as this HV mod is essentially the same.
The only downside I would say about the amp is that, even with the Thump and Bass on 10, the amp does not have a hugh amount of low end. It could be speaker situation, but I don't think it is. I have a Mark IV that has much more low end with the same speaker (Mesa 2x12 with 2 greenbacks).
