100 Watt HRM recording / compare to a 30 watt non-HRM

[Bob-I]

EDIT: I did a quick recording of the Princeton chassis / iron non-HRM. Since the recording equipment was still set up, I left everything else alone so mike position, board settings, guitar, etc are all the same.

Setting on the non-HRM, again a scale from 0 to 10

Gain 6
Treble 7
Mids 6
Bass 6
Drive 4
Ratio 4.5
Master 3
presence 0
PAB off
Mid boost off
LNFB 22M

Remember that this amp is using Primceton iron so the voltages are far lower. B+ is about 360 and it's only 2 6L6's instead of 4

I have such difficulty capturing the sound of the ODS. On this recording I used a Sennheiser 609 into the Alesis Firewire mixer. It's a tad better, but still not 100% what this sounds like live. Forgive the clams, I forgot how this arrangement went and got lost for a bit.

Guitar is a homebuilt 2 Hum with a 24.75" scale Warmoth neck and Kent Armstrong PAF's. I used 3 PU positions (out of a total of 6)

Settings.. on a scale of 0-10

Clean tone
gain 6
Treble 4
Mids 7
Bass 6
Clean master 4

ODS
Drive 6
Master 2.5

That's wacko. Somehow an old take ended up overdubbed.

There's no bugs in Cakewalk right?

EDIT: Fixed. Try again.

Thanks for posting, Bob. I really liked the tones, the OD is "greasy" for the lack of a better description. Very rich. With this settings, my amp isn't as gainy. What are your OD Trim and HRM settings? Also, is it BM PI?

I use similar settings, except the input volume is hotter (around , OD Trim is mild, and clean treble is almost zero (my amp is bright!).

The OD trim is fairly high. I haven't measured it but my guess is about 70%. I adjusted the HRM by turning all controls to min, then adjusting the bass until it was on, maybe 30%, mids just above midway, and treble at 50%.

No, it's not a BM PI, just standard ODS PI.

I found this amp very bright at first too. The OD1 coupler started as a .0022uF Xicon MPP. I added a second in parallel and it took some of the extreme highs out of the OD side, but left the cleans nice and bright.

I don't like to add too much gain because I like the tone of the gutiar to come through.

Thx for listening.

Very nice Bob! What tubes did you end up going with? ( this is Brandon's chassis, right?)

Just when I thought I had my non HRM dialed in and you had to go and post that! It definitly sounds different enough to have both flavors. Anyway, great job!

Mullard re-issue in V1 and V2, Sovtek 12AX7LPS in V3 and Tung SOl 6L6GC TDR in V4-7

Yea, it's a completley different feel too. I'm pretty settlted on the HRM but I have a cool little non-hrm in a Princeton chassis. Gotta have both.

I'm still waiting on the Brandon head cab which he shipped out a few days ago. As soon as it comes I'll be taking this amp to a gig.

PAB? Mid-boost? I'm always more interested in this than any other setting on an HRM. Next would be the HRM trimmers...mind sharing those settings?

I snuck a quick listen @ work and it sounds pretty good. Where'd you get the backing track? I'm so outta touch on these killer backing tracks you guys use.

Not at all. The HRM settings are already posted. PAB on for the ODS tone, mid boost off.

I could tell you, but then I'd have to kill you.

Actually, I don't remember where I got this one, but I've collected quite a few just surfing around forums.

Thanks for posting the clip. It would be fun to hear your non-hrm princeton with the same song and recording setup.

[Blindog]

+1 lets hear it!

That would be great indeed...

Great idea. I guarentee it'll still sound like ME though.

I'll see if I can get to that in the next few days.

I'm surprised no one's asked about the speaker. It's an Emi Delta Pro 12A in a Boogafunk Thiele cabinet. The low end thump on this thing is amazing, it rattles your teeth even at low volumes. As you can hear, the highs are crisp and clean.

Ah, a ported cab...that's why it's so hard to record....

Did you try multiple mics at various points in the room? The lows need a separate mic.

The amp sounds like fun!

Actaully I found this cab easier to record than either the closed back of the open back. I've tried the multiple mike idea, but the room I'm in doesn't really work well.
