I have both. They are different enough to justify having both, but they are clearly similar.
BM with Alnico is lovely. More typically John Mayer
HRM with EVM is cleaner, but less 60s Fender. More typically SRV
I'd have the BM if I had to keep one

I never noticed the pull switch on the HRM OD Level before. I think I would prefer the opposite! I need to set the trimmers

Cheers

just tell Nik what you want to play like
But tbh these are the most flexible amps I've ever used, so I think no customisation is really needed
If you want a JM sound, I thought the Bluesmaster HRM might be better. Depends if you like ultra-clean fender sounds through an EVM12, or blackfacey sounds through Alnico drivers. I like both, so got a BM and a plain HRM

not mine, just saw it on ebay:

now Matt Schofield has a signature pedal:

I would have thought so too, but in interviews he says he doesn't like the crystal-clean sound, and likes it a bit more ermm.. unclear
When I bought a CD at his gig, I asked which of his pedals he'd most recommend. I just wanted a nice one to try, but he fairly told me it would not replicate his sound. Anyway, it was a Providence Stampede, and  when I got one, I found that it somehow crisps up a fender super, so maybe he starts dirty, and uses a pedal to get cleaner

Personally I prefer to do it the other way round
I didn't think the £4k two rock I tried was in any way better than the HRM 100, but really - why should it be?

hi mckinku, you had previously said "Overtone Skyliner HRM 100
Clean tone is practically the same as OTS or S&M. "

But the OTS I had was much less clean than this HRM100 I just acquired
Not complaining, just want to know what advise to give others, the OTS was built by Nik, the HRM100 by MJW

I've had a BM50 for 2-3 years
Before that I had a Fuchs ODS30
I did have an OTS, I found it was a little more like a Super - not as clean (with an EVM12) as the BM with a Celestion Gold
Now I have an HRM100, and it is much cleaner than the BM50
Is this normal, or did the builder change something?

Matt Schofield's Two rock has broken I think, his facebook page is asking for a loan amp for tonight

£85

the jtm45 is awesome, but needs full volume to develop its character
that said, using it at home with a really good boutique OD could crack the level issue, and leave you with a proper amp for live use. How about a Lovedrive Eternity burst or clone?
I really doubt that MV or an attenuator would be as good. I had power scaling on 3 amps, no joy for me. I've tried all these, I now use pedals, after originally abandoning all the crappy pedals in the 90s - today's boutique pedals have killed the myth that only power stage OD is musical, I am now very critical of some amps for their OD offering, contrary to my valve-amp-preferences, the very best pedals can more than match the OD provided by many amps

For quieter Marshall tones, the Ceriatone EF86 36w TMB is excellent.
pre- PI master vol though, but more into ACDC tones I think, and switchable to 18w
Then the EF86 channel adds a very different channel.

btw I know Marshall build quality is lower, but for quieter fun at home, the Class 5 combos are worth a try

I have a BM50. I like the internal OD set to a modest amount of grit, but not Santana-type OD

When the BM50 is set to ultraclean I sometimes use a Zendrive 2 with it, works very well for slightly more driven tones
For just a little grit, a Klone
for feel but more grit, a Honeybee clone, backing off the vol with this is very Mayer I think

I could ditch the rest and stick with these 3, but they are all doing something different, so choosing would be hard.
All excellent for playing JMayer-range of sounds on a strat


I tried a Zendrive v1.0. very nice, but the v2 is nicer

bear in mind that running 2 different speaker types in parallel does not have predictable results, since the impedance of each driver varies with frequency, each driver will not have a 50% share of the signal at all frequencies. i.e. this will not sound the same as 2 identical amps run into the same 2 drivers individually. It usually takes a lot of trial and error to find a pair that works well. You might be well advised to copy the Matchless/Badcat approach, or anyone else that sells mismatched 2x12s

AFAIK all "normal" guitar speakers colour the sound a lot, but in different ways, probably 20x as much variation between models and brands than you'd get in hifi speakers
Very few are as clean and uncoloured as the EVM12.

Certainly it's not just Celestion with this type of colouration (which for most amps is usually considered a good thing)

it sounds nice with a gold or a fane axa
better with a real matchless mismatched pair though
