If so, I have both and there really isn't any difference. The speaker will make a big difference though. I was told by someone that you need to get a low powered speaker with a 1 watt to get the best out of it. I certainly did not find that to be true with my JTM1. A vintage 30 sounded good but when I used a 120 watt Eminence Manowar, things changed. I got a ton of bottom end that shook a few things in the room. The top end was quite crisp and I could back down on the tone a bit.
