Interesting "tech notes" in the Egnater manuals

[jayj]

Looking at picking up an Egnater Renegade. Found some interesting articules at the end of the manual that might be of general interest here, presumably by Bruce Egnater himself.

http://egnateramps.com/manuals/RenegadeManual.pdf

Page 16:
"WATTS vs VOLUME and other stuff" -- all about the difference between why Watts and volume, why the EL84's and 6L6 tube mixes dont' sound very different at low volumes, etc.

Page 17:
"Sound dispersion" -- why your audience has bleeding ears, but it sounds great to you and some possible solutions.


Both interesting reads, figured I'd share.

Thanks for the link. The information on p. 17 is not new, but I had not heard of the 4" x 1" foam disk trick before. I wonder if someone sells these--or at least the material.

what if you tipped your amp so it is beaming the highs to the ceiling? My amp stand points my amp up anyway.

The part about the watts vs volume is something that we all learn eventually as we learn more about amps. I just wish some of the young cats could understand it off the bat instead of automatically thinking that higher wattage is better for everything.

The sound dispersion stuff is gold. I hate when I go to a show and standing off to the side sounds better. I always EQ my amp with a bit less treble than I think I need and try to point the cab upwards. Slanted cabs work wonders for sound dispersement.

I'd like to know too. I've been using beam blockers and they're ok but I wouldn't mind trying the foam disk.

I think the point isn't so much where you point your amp, but that you are in front of it when you EQ. The problem with that though is that it seems like if you tame the treble directly in front of the speaker, it has to cut a lot of the highs when you are standing off center from the speaker.

Either you put the amp way back on the stage behind you, and/or you use sound reinforcement (aka PA) to do this "right" for a live venue.

One of the selling points of the Renegade for me is the additional option it gives you here: the XLR line out with speaker emulation. This way I can point the amp right at me as a monitor (opposite the audience), and let the PA handle the rest.

If you have the cab pointed upwards at a good angle, especially if the stage is raised off the ground, the sound direction will fly over the audience's heads, and they will (in theory) hear what you hear when you stand a little off to the side of your amp. When you do this and you're mic'd, it's a good idea to put the mic a bit in front of your amp at the edge of the cabinet instead of dead center, that way the PA system is picking up a similar tone to the non-directional sound from your rig.

In a non mic'd venue where you're basically playing in a corner of a room at floor level with your amp pointed at the audience, like say gigging at a bar, those foam discs are probably the best bet.

This and the others are great links! Very helpful and informative! Thanks again!!!

I really need to get a plexiglass baffle- like the ones Clearsonic makes. I cannot think of a better tool to getting better sound for your audience. They direct the sound upwards so your audience doesn't get those shrill, center cone highs. Joe Bonamassa is a major user of these.
