The rig you wish was loud enough to play live....

JoshuaTSP · #1 06-16-2011, 09:18 PM

For me it's an old Traynor YBA-1A....sounds SOOOOO good....but not nearly loud enough for a rock show......no headroom.

With really efficient cabs you might be able to. 2 BFM Jack 15s or Omni 15s might work.

I'd just use guitar drivers for an amp like that. Lots of them.

50w guitar amp in a loud rock band? overdriven maybe but clean....NO WAY!

rpsands · #5 06-16-2011, 09:49 PM

Get enough guitar drivers and it'd work fine. You'd probably need around a full stack (two 4x12s).

It'd be pretty light on the low end but you could port the boxes to get a little more juice back.

I could absolutely gig an Ampeg 8x10 and a V4B, and 100 watts - not that much more than 50 watts. Nothing more speakers can't handle.

I've used a B-15N with a loud rock band before and no PA in about a 150 seat bar. OK, it started struggling midway through the 3rd set once the guitar player started boosting, but up till then, it was hanging in there pretty well.

JoshuaTSP · #7 06-16-2011, 09:51 PM

I tried that...out of circumstances.....100 tube watts did not work for me.

but that was through a 2x15 in a loud stoner rock type of situation.

rpsands · #8 06-16-2011, 09:52 PM

For reference, an 8x12 with guitar drivers could come in around 108db in broadband sensitivity, down to 90-100hz or so. With 50 watts, that's 125db.

A standard Ampeg 8x10 is about 100db or so sensitivity, with 100 watts that's 120db.

There's no replacement for craploads of speakers. A high end 2x15 with bass drivers can take lots of power, but gives up lots of sensitivity to get low end extension and power handling.

...but it can't handle the clean output....right?

I don't know, but clean tone always seems to cut better than dirty.

What are you talking about it can't handle the clean output?

Of course it can. 50 watts is like 6 watts a speaker.

If you absolutely must you could put a 70hz 4th order bw filter ahead of the amp, which would drastically improve your power handling.

As long as the amp can put out 50 watts clean, the speakers would reproduce it--with the edge guitar speakers have.

no question one kilo of wattage is enough,,i don't have cabs worthy right now,but i also have a PV combo 300 that when i stack a 4x10 cab on and plug in a pedal is unbelievably loud(comparing to a thousand watts it's phenominal)

but yeah,long live the practice amps they do what they are supposed to but meaty tone,enveloping a room larger than a bedroom,well,,,,,,,,,,buy a PA system and tag into that

(ok where wuz i going here when i logged on?)>---)>

I believe this post is hypothetical.

As boastful as it my sound, My rig is big enough to play loud enough for most gigs except a large concert hall of course. Even still, my rig is used for stage monitoring. The better I hear myself with the best tone possible, the better I play and that transcends in my overall performance! Nothing is more frustrating than when you can barely hear yourself or your tone is not happening, right? Doesn't that same frustration reflect in your overall performance?

If you want your sound dispersed evenly(if that is truly possible) along with a good mix with your band, You should be using a P.A. and pray you have a good soundman with good ears and taste. Then the band should play at a respectable but inspiring stage volume level and not try to compete with the P.A. from off the stage!

I used a Jack 2x10 once. More efficient than the 410 I had by along shot!

Wonderful Wonderful design.

And Josh, these are the cleanest cabs you will ever here.

I think the YBA1A is 90W, but I get it. I used to be in a band with a heavy handed drummer and gutarists with a Fender Super Reverb one side and a Twin on the other. We were pretty loud.

I had been using my B15N with an additional ported 15 and it sounded like a sousaphone it was so driven. Bought a MusicMan HD130 and a Fender Bassman 135, and neither sounded good through a Peavey 2x15. I sold the MM (didn't like the breakup tone) but bought a set of Bill Fitzmaurice cabs - this was back in 03 or 04 when his stuff was more underground than now. I had a Tuba24 sub and DR250a built w/ passive crossover.

The Bassman 135 through those two cabs had simply incredible sound and was waaay louder than I needed. Low extension, projection, dispersion. They have it all. Your 1A would rock through them. By circumstance, I had to play the B15N amp through the BFM stack with that band. The poor girl's Sovtek 5881 were so tired by that time it wasn't a fair evaluation. With the 135, it was one of those situations where you were just kind of cruisin along with plenty of headroom. I didn't think the 135 worked all that well that way, but it it was a fun process to figure out... in retrospect, anyway.

But for me and my current vehicles, they're more of a pain to pack and haul even though they are light. I just don't need that kind of output any more. We only play places that require strong backline a few times per year.

I just played Buffalo's Pride Fest on the waterfront (thousands of very enthusiastic attendees) with my B15N. I wouldn't have brought it, but the sound man from one of our monthly club gigs was working it and I knew the monitor on my side woud take a little of me if it needed filling in. It didn't, but he gave it to me anyway and it was perfect. He absolutely raved about the B and how it worked for him out front. Called it HUGE. Sure helps not having much coming off the stage if you've got the right PA rig.

I am soooooo digressing. Anyway, the only reason I have anything besides the B15N is because its output is so limited. It doen't come up much, as I said, but it does. If it's an easy load in, the SVT 810 rig comes out. If not, it'll usually be the modern stuff - MB Fusion & a pair of Eden D112XLT or whatever.

I loooooove good PAs run well.

will33 · #16 06-16-2011, 10:36 PM

Heck, if I could afford such a novelty, one of my bass rigs would involve about a dozen each valve jr's and sealed box vintage 30's.

Ben Clarke · #17 06-16-2011, 10:58 PM

I should mention that a vintage flat back 810 with that MB Fusion amp works really, really well too. If the load in relatively step-free that's an easier haul for me than a couple 112 that I have to carry.

countrybass007 · #18 06-17-2011, 08:57 PM

I think most of us oldsters wish the Ampeg Portaflex amps were able to put out more.

GeneralElectric · #19 06-17-2011, 08:59 PM

No amp is not loud enough. Get a microphone.

That's a 90 watt amp. With an efficient cab you should be able to rock that thing just fine. I did it for a few years with an Eden 410XLT. You might want to have it checked over by a tech.
