Mic'ing a closed-back ported cab

Post by Normster »

I installed a RW&B in one of Loren's ported cabs yesterday and got this glorious woody lower end tone that I've never gotten before. Problem is, I can't seem to capture the tone when recording. I only have two mic's, an SM57 and a Nady RSM-5. No matter what I try I can't seem to capture the tone. It's like the tone loosens up by the time it gets to the computer. :?

Here's the clip I was working on. (Guitar is an Ibanez AS83. Amp is a "stock" 100 watt HRM 101 build using Funk's chassis and boards.)

Any recording, mixing, mic'ing tricks to help bring out the woody bottom end?

Have you tried micing right near the very edge of the cone? I find it is often the mellowest place to set the mic, then move it in towards the center to increase brightness (not at an angle, just straight at the speaker).
Of the two mics you named I would guess the SM57 would work better, but I'm not familiar with the other. For myself, I don't much care for the 57, there is an upper mid peak I don't like (great for snare though). I prefer my Sennheiser 609, similar sound character to a 57 but better IMHO, same price.

Looks like the Sennheiser 609 is available on ebay for $80 so I think I'll give it a shot. As for mic placement, I seem to get closest to the tone about 2" from the edge, straight in, and about 4" back from the grill. I think part of the problem is that the ports are adding something to the tone that I haven't been able to dial in yet. How the hell do you mic ports without getting bass mush? :?

nice sounding clip. Try mixing the 2 mics with the 57 at edge of cone and the nady pointing back at the speaker at a 6" height angled toward a point on the floor 2 inches past the speakers "bounce" point (if you had a straight edge on the cone angle, wherever that intersects the floor is the bounce point).

I know what you're saying. That clip sound glorious but if it's missing that woody charactor I can only imagine what it soulds like in the same room. I love that organic woody tone you describe. One of the reasons I've never liked Leslie simulators is they never capture the wood.

Tell me more about the cab. I looked on the brownnote site and can't seem to find a ported cab.

There are some pictures at the Brown Note forum.
Really nice flamed maple cab that I would be afraid to gig with.... :)
But Moss probably would have them available in tolex if they are received well.
But scant details about pricing and other info.

I hadn't even thought about that, but you may be on to something. I may be missing that relected bass coming off the floor.

Bob, the cab is a one-off prototype at this point. Loren is working on a slightly smaller version of the Dumble ported 1 x 12 cab that will be tuned for the G1265. Alf Hermeda has generously helped with the analysis and dimensions so it's getting close. It's similar to the flamed maple cab on Moss's site but built with birch ply (so it IS gig-worthy).

The maple cab is a show-piece so it would take a lot to pry it out of Moss's hands. I think the bare wood cost more than the whole amp! :shock:

Normster,

Your ribbon mic goes down to 30Hz and the SM57 only goes down to around 40Hz. You may fare better with a wider range condenser or two at ear level in the room. An electrical set of "ears" to hear what you are hearing - where you are hearing it. Many condensers will capture down to 20Hz. Mix that content in with your 57 and see what you think.
Good luck. Nice clip! I can really tell that your new amp has you playing more.

Thanks for all the tips, guys. I took my son's advice for this latest attempt. He said, "Why don't you dial in the amp for the recorded tone instead of the room tone?" Doh!

Anyway, another take over the same backing with the bass rolled off, mids bumped a bit, and a different reverb patch. Getting closer. Now it's time to learn the damn song!!!

Sounds deeper and with a richer texture this time around.

Try the close mic with the 57 and ambient with the other mic. You get both the speaker/cab and room tone.

Also, you could be hitting resonance frequency(ies) of the cab wood and may want to experiment with placing a mic facing the side or back of the cab. Sounds odd, but you may be surprised with the results.
