Best boost pedal for RM4

[audioholic]

Where the EQ is placed in the chain is more important than anything. If you place it after your guitar but before the preamp, then you will only be EQing your guitar and not the amp itself. You will really notice the difference placing an EQ post preamp. Idk if a stereo EQ will really be all that different...

And, to end the hearing controversy, here's a good test I found that goes all the way up to 20 KHz: http://www.digital-recordings.com/cgi-bin/www-ht-pro.cgi I can hear all the way up to 20 KHz clearly, oddly enough these frequencies don't really bother me :?: . Although, I didn't know some people couldn't hear past 14 KHz, but that explains why so many people claim 16 KHz does nothing on the MXR 10 band EQ .

I can hear up to 18k, but as the frequencies are lower, and go higher, it requires a significan amount of volume in order to hear it, Fact is 18k is VERY high, you saying you can clearly hear 20k, as easy as 1k? common man

Most playback systems won't go much past 20k, look at the specs. if your monitors claim they don't go past 20k, and you are hearing 25k, then thats just impossible.


either way, these frequencies are doing little if any to a recorded source, so adjusting 20k on an eq is pretty pointless, let alone makign any significant audible difference, specially considering the limited freqquency range of a guitar speaker, which is not full responce.

Actually the frequencies above 10kHz, especially 15-20kHz are difficult for many people to hear but they are audible and do make a difference with anything recorded. Depending on the instrument or voice recorded makes the difference on if it is really "noise" or "sound". Their were some studies about these frequencies and higher. It showed even if you cannot hear above a certain frequency such as 10kHz or 15kHz your brain can still notice them. In actual listening tests some people have up to 25-26kHz hearing and brain scans showed brain acknowledgement up to 45-50kHz . PCM @ 44.1kHz does end up allowing up to 22.05kHz without blocking (half of the 44.1kHz) and can sometimes have energy to 25kHz. High rate PCM and DSD such as available on DVD (DVD-Video and DVD-Audio), and SACD have the ability to go up to much more than that, such as frequencies of 90- 100kHz.

Also, it probably does not make up much difference in guitar rig to worry about the frequencies in my previous post, but up to the mid teens, such as 15 or 16kHz can. The trouble with those frequencies are they can and will be masked by other ones. I find the most important high freq. area is between 4-6kHz for guitar, after that it is less important.

like I said

Air, that is all these higher frequencies are. And while our brain may be able to react to higher and lower frequencies, doesn't mean we can "hear" them. Our brain may be able to respond to it, but doesn't mean its doing anything signifant. You could roll off frequencies above 15k on a guitar and it won't do anything significant what so ever. There may be upper harmonic sounds at this level, but its not significant.

When I apply eq on a master buss, I tend to add 10-12k up top to add air, but its not really doing much important as far as overall mix goes. Converters running at 44.1 will most likely be filtering out top end frequencies to prevent aliasing, and most playback systems have a tolerance of levels up to a point, in which they have a much harder time reproducing higher and lower frequencies, check the specs. I doubt most playback systems will be able to reproduce such high frequencies easily.

Microphones used to capture audio have a limited frequency range as well. usually up to 18-20k with tolerance.

My point is, saying you can clearly hear 25k as easy as 1k, its not possible, and I stand by that no matter what anybody says or claims.

I agree with you audioholic, that those really high frequencies don't make much of a difference; for guitar, more than 16 KHz is pretty useless, but raising 20+ KHz for vocals can make a world of difference. When it comes to guitar EQ, I'm not even using my 10 band EQ unless I'm recording. However, I agree with randalls4ever that really high frequencies do make a difference when recording; the difference isn't really an EQ difference, but more of an "extending" or "opening up" difference. However, if someone played a recording with a filter on 18 KHz, I probably wouldn't know that filter was there.

You know, I really miss recording to tape @ 15ips.....oh,well.....

Back to the boost point. Frequencies most important of all for guitar are generally 120Hz to about 6kHz. A great way to boost pedal wise would be an eq pedal such as the Danelectro Fish and Chips, inexspensive and quiet, or the MXR 10 band or 6 band units. My current favorite boost pedal is the BBE Boosta Grande. A great boost that changes the tone a little. Not totally tranparent, but close. If you want to try something else I have been hearing about a new pedal called the EP-pre. It is a recreation ot the preamp section of a EP3 Echoplex delay. Sounds interesting. The guy building them, Peter Clinch, is out of Australia. His website is http://www.clinchfx.com/
This is supposed to be pretty cool, going to get one soon. Good luck
