I want to pull the driver and check for liner/stuffing. I suspect it is bare...
A Hilti hammer drill is the time honored solution. HTH...
Does the cabinet have handles that you can remove to take a look inside?
If this is the first generation MB-115 combo, just remove two screws on each side. Then hook a large allen wrench through the grill at one corner and pull. You may need to do this at two corners before it comes free. When you install the grill make sure those screws are in pretty tight to avoid grill vibration.
Sweet! Cab was bare as expected. Now has 1 layer of poly batting. I’m going to button it up in the morning and gig it tomorrow night. Then decide another layer or not...
Bob Gallien has mentioned that he feels it works better without, FWIW.
I had a NEO 210 a few years ago that was un-lined. I contacted GK and was told it was designed that way. I lined it anyway and was pleasantly surprised. It had more clarity and better mid presence. I don't in any way to claim to know more than Mr. Gallien, but I trust my ears.
I don't necessarily trust anyone's ears, including my own.
All good, just wanted to get that out there though.
I lined an mb-112 that I had briefly. I felt it dropped the tuning - or maybe suppressed the low mids. Either way I felt I had a more solid low end, or something less boomy. Now, that could also lead to maybe overpowering the driver and Bob’s concern may have been based as much in reliability as tone. IIRC later generations of the amp are delivered lined. I reserve the right to be wrong there however. I haven’t been following closely for a long time.
Anyhow, I’ll give it a test and either add more, pull it out or leave it as is...
Cool. Not sure if I can make it to your gig tonight, but it's on my radar at least.
Well it’s also the first outdoor open mic of the White Buffalo season. If it’s dry then that might be fun. At least an opportunity to catch up with the Baja returnees ;-)
Thanks for the heads-up. If I don't play the open mike I could do both for a while. Or I could just take a nap...snerk, zzzzzzzzzz.
While taking the driver out of my MB115 to measure the TS parameters (out of curiosity) I found that the cab had no acoustic damping material. Appalled, I lined the entire interior with dacron and eagerly anticipated hearing the improvement. I was indeed amazed... at how the change had sapped the tone of energy and aggressiveness, taking much of the 'life' out of the sound. I reduced interior coverage by half - still lifeless. Reduced to 1/3 coverage, including behind the driver and had a satisfying compromise. IMO, this is strictly a personal preference issue. Bob Gallien's design choice is perfectly valid. Fortunately, if you disagree, it's easily adjusted.
Thanks. I thought I remembered all of that, save that you were the one who posted it.
Well the light stuffing job I did seems to have reduced the boom. So far so good.
Seemed like an improvement from your last gig there to me, even though the room stuffing wasn't really working in your favor last night.
