Hey Folks,
Newbie here. I want to purchase either an OTS or HRM. As best I can understand from clips, YouTube, etc., I think I want an HRM.
I play Bluesy Rock, some Hard Rock, and maybe a bit in the Robben Ford-esque Blues. I want the ability to get a little into the Marshall neighborhood, but I already have a 'mean' Marshall-type amp.

From what I can best determine, HRM Mk. 2 might be my best choice.

Can someone elaborate the differences between HRM and HRM Mk. 2? I see Mk. 2 has EL34's. Any other differences that are significant?

Hey Noel

I have an MK2 50watt and the FM 50 watt. I have not played the regular HRM so I cannot say for sure, but based on conversations I have had with Nik and other HRM owners the MK2 will have less gain in OD channel than the HRM. MK2 is smoother for lack of a better word. Although the MK2 uses EL-34's it does not sound anything like my Marshall style amps.
If you already got a Marshall, you could do what I do and run an ABY to both for the best sound if possible. I almost always use my 2550 on the left and then swap between the MK and the FM on the right. Since using this setup I almost always feel something missing when playing on either amp alone.
You cant go wrong with any of the OTS's
I added a switch to bypass the HRM tonestack on my MK2 which I have found very useful BTW. Gives up a little more grind when HRM is bypassed. Maybe ask Nik for this mod when you order if you get an HRM.
