insane gain... no pedals*

Rockstah, by krang I'm not referring to the ocsillation which I can hear also. I'm just referring to the toney midrange you guys are getting. It almost has a singlecoil type tone to it.

yes. every clip i hear it. most apparent when playing a chord. its a high pitched non musical sound. mosquito buzz on the notes. PO

first thing i would check is that speaker being mic'd - from behind very gently moving the cone back and forth - does it make a rubbing sound or not? a scratching sound - a drag of the voice coil.

adamsapple - take this with a grain of salt cuz i'm a hack if there ever was one - but just to let you know what i do to try and achieve that single coilish mid range is i put put the pickup ring on backwards which raises one coil closer to the strings than the other coil - i hear that same sound in ed's tone especially on old live bootlegs - it's a kickin' sound with lots mid dynamics - i attribute it to him hand winding a pickup and coming up with an uneven amount of resistance on each coil rendering the pickup a hybrid between single coil and humbucker - the better way to try out this effect is to run one of the coils to a pot that can variably send the signal to ground - so you are mixing the balance between the 2 coils with a volume pot on the guitar - i had mine wired like that for a while and really liked it - then i got lazy and switched to the hack way i described above... but... wht do i know.. i can't even hear parasitic oscillation for heaven's sake! wish i could. thankls for your help - i'm going to see if i can get rid of it - kinda hard though since i can't even hear it!

I don't hear it.

any reasonable person would be sipping beer by the barbee at this point on memorial day weekend - but i have never claimed to be reasonable...

re:
parasitic oscillation or blown speaker type buzzing noise

this is a different speaker in the same cab and...
the mic is about an inch closer on 30 degree angle with the close edge of the mic almost touching the cloth and off dead center by about an inch and...
i swapped the 68 tone stack out for a 69: 33K/500p and...
it's a 560p cap on the mixer and...
it's got no bypass cap on V2A and...
the presence was knocked back to 5 and...
the eq boost is an mxr 6 band i got off ebay - arrived today - woo hoo! it is set with a very slight frown/boost - it's too noisy to boost any more than about 4db-ish...

other than that it's exactly the same. rockstah/adamsample, still hearing the oscilliatory noise?

here it is dry:

crappy playing here - sorry - it's about the sound.

Rgalpin, the oscillation I'm hearing is a high swirling noise that you can get from mixing software. It's not your amp or speakers. When I've mixed a track and added lots of reverb etc. and then compress to mp3 format I've gotten that hissing noise also. FWIW.

Your real close...To my ears you are too trebly and a tad fizzy. Looking for more compression in there too. Cut the highs. VH1 is my favorite EVH recording but that is even more trebly then VH1 is.

cool and i agree - thanks for the input - i have a few things i'm looking forward to trying in order to tame that high end and warm it up - sooner or later though i think i'll end up with those G12Ms - they are sounding sweet in the clips i'm hearing.

Have you tried the new caps yet?

rgalpin · Post by **rgalpin** » Sat Jun 10, 2006 6:40 pm

my amp is hurting right now - for some reason the plate voltage dropped from 465 to 420 - now i'm having to change the bias reisistor in order to get the bias adjusted right - don't know what happened...

Just listened to these new clips, I can't hear parasitic oscillation anymore. It was definately coming from your amp though, after trying to get rid of it for months, I can spot that sound a mile away lol.

Somebody should make a sound clip of what PO sounds like.

I agree. I still am not sure I hear anything. Are we listening for high-end fizzes?
