Look at the frequency response of an electric bass speaker, then the frequency response of a sub. The only way you get what's coming out of the sub to sound close to the same as what's coming out of the backline is with some serious reduction of the low frequency content in the PA channel, and probably some midrange boost as well. It's different with recorded material, as the necessary EQ adjustment is done in the mixdown. Even with top international touring acts the only FOH guys I've heard who get it right are either bass players or recording engineers.

I see your point. Although, I have to kinda question the logic behind the sound a bass cab creates as being the benchmark. It seems a vast majority of them are either designed to be compact or big with a lot of drivers in them... Designed to sell to the uninformed masses instead of being designed to sound accurate or good. I'm sure exceptions exist. And, "good" is certainly subjective. Much of what guitar and bass cabs lack in accurate or clean reproduction has certainly been accepted as desirable main stream tones (distortion?). Not to say having the lower register enhanced is accurate, but more to point out that, tastes differ. What it "should" sound like is highly based on what we (as individuals) have heard before and think is "normal". Isn't it? I think it's deponent on the genre too.

When I play my Ubass through my little 10" amp, it sounds good. When I played it through and SVT 8x10, it sounds good. When I plug directly into the mixer and play it through a T39 and 2x6 SLA, tuned with a 15dB bump at 45Hz... it sounds phenomenally amazing... to me. (well, my picky ass dad too) The tone is smooth (that's what I prefer, smooth clean bass) and the bottom is lusciously visceral.

I had a curiosity I'd like to play with when I get the chance. Mic the bass cab to get it's tone and highpass it like you say, 80Hz ish. But, then also DI pre cab to get a pure undistorted and/or colored signal to fill in the bottom octave to taste with High/Low band pass filters. Cab tone, clean bottom energy.

You've been doing this stuff for probably longer than I've been alive. I'd be a silly fool to not give high regard to your experience and opinion. So, I'm just thinking out loud here. I'll try high passing the bass at 80 next time I get a chance. See what I think. I highly appreciate the shared insight Bill.

When you take the DI out of the back of an amp, always set it to pre-EQ if that's an option. Otherwise, you'll be getting the EQ he needs to make that little speaker sound good to him - which is not the same as having a PA with subs. If the DI output is only post EQ, then use a Direct box.

small guitar enclosure - What's to chat about?

#1114 Post by Grey Owl » Wed Oct 13, 2021 12:19 am

Gidday Guys & Girls,
Am seriously thinking of retiring my Mesa guitar amp as getting heavy for this old back. :cowboy:
On this forum, has anyone discussed something much lighter?
Looking through Bill's pantheon, how about a short SLA with 2 Alpha 6's no tweets. 8)
Simple handle on the top plus I just saw a cheap n cheerful amp on-line.
Perfect for jamming around with mates???
Could be lotsa fun without the weight. :feedback:
Cheers

Last week we had a house jam with the guitar player using a Supro 5 watt tube combo loaded with an eight. It was plenty.

I went through the same thing a few years ago. I got rid of my Mesa Mark IV. When the Mark V:25 came out, I grabbed one. After using it with a cab for a while (it only came as a head then), I built a cab with a neo 12 and turned it into a combo. 25 pounds all in for a 10/25 watt screamer full of Boogie magic.

It's been a great little workhorse and gets a whole lot of "what's that?" from other guitar players. In fact, the other guy in a band I was in had the same head, so I built two of 'em.

Thanks Kevin,
Nice build there.
What would be the equivalent of those out of stock drivers today please?
Cheers

I'm not sure which he was referring to, but a quick search turned these up as an option... Eminence Patriot 620H. A little spendy though.

Yeah, the driver i used were a buyout special back in the day.
The H20s do look pretty cool, but I though the Alpha 6 drivers were great too!
