Dual Rectifier, 3 channels is driving me insane

[fluff191]

The trick is to keep the pickups tight in the cavity of the guitar. Get some foam and put it on the bottom of the pick up, and put it back in the guitar. You want the foam to take up the space between the bottom of the pick up and the cavity of the guitar.

I do this for all of my guitars.

Turn the channel master down to around 10:00 and turn the master output back up to compensate for the volume drop. It'll produce a cleaner signal than you're getting with the channel master up at 12:00 as high channel master settings tend to overdrive the effects loop.

Your pickups shouldn't be the issue. EMGs are filled with epoxy to keep the coils from vibrating. There's also no requirement to ground them due to the design of them, so the wire coming off your Floyd can be left unattached. Taping it off is a good idea.

Consider only using the OD808 when you're soloing. The EMG81 is already EQ'd with lots of treble and a cut bottom end, so you don't really need an overdrive pedal to produce that aggressive result like you do with passive pickups.

Yellowjacket; I searched more info about the Mills Acustics and they only build and ship their Cabs by order and there's no local dealers to try at a local store, i'm from Barcelona and the shipping cost can be a problem :-S, I'm still thinking on 4x12 as well... crazy cab world xD

Mastora and screamingdaisy; I changed my string 3 days ago, and maybe the foam on the pickups have to wait till the next change, but i will do the procedure on the springs cavity on the next few days. Screamingdaisy, are you sure that nothing will change with the foam under the emg?

It won't hurt to try it, but I don't think it'll do a whole lot. Microphonic feedback from pickups is usually due to loose coil windings within the pickups themselves, and dampening the vibration tends (via foam or other methods) usually helps with them. EMGs on the other hand are filled with epoxy to keep the coils from vibrating, so adding foam to dampen vibration won't make a difference since the coils can't vibrate anyway.

To me the only thing that looks unusual is how high your channel master is relative to the amount of gain you're pushing. I find Recto's generally work best with the channel master of the loudest channel between 9:00 and 10:00, with the other channels adjusted to match volumes.

 

[mastora]

it is possible that the pick up itself my be vibrating too and causing a bit of feedback. He already said that when he pressed down on the pick up with his finger , a lot of the feedback went away.

I will try to do a friend's trick, he told me to put some cotton into the springs (into the spiral), and finally cover the springs with the foam like you said.

One of the things you might check is if you have a microphonic pre-amp tube. I have had a couple over the years and they cause all kinds of feedback and noise issues. You could try plugging your guitar into the distortion pedal then going straight into the amp. Turn the volume off on the guitar. You'll probably hear a pretty good amount of hiss. Then start tapping on the top of the amp pretty hard with a couple of fingers and see if you hear any high pitch sounds or rattling coming from the cabinet. If so, you might have a microphonic pre-amp tube. You can also move the amp to the floor a little bit away from the cabinet and see if that helps. (This eliminates the cabinet shaking the head and the tubes) Good luck.

Everything i'm reading from the op makes me think this is just a tube problem. I'm willing to bet a total retube would cure all of these noise/tone problems.

I'm thinking it's either that or the cab. I run my presence high on the modern setting because it's not affecting the top end presence so much as the overall "growl" of the tone so to speak. To me I consider presence on modern the "Raunch" or "throat" control. It's in a different part of the chain. I'm assuming the OP is running modern mode. Check your preamp tubes. If you have extras to swap with, try that one at a time to eliminate a problem tube. If it's not that, then it's probably the cab. Randall cabs are generally well built so if you're looking into speakers, check around. WGS seems to have great prices on those. I don't have any personal experience but people love them. I have a Crate Blue Voodoo 4x12 that I loaded with Hellatone 60Ls that sounds damn good. Also, don't be afraid to buy used. I got my Recto 4x12 off Craigslist for $400 with V30s and the only thing wrong with it was scuffs on the tolex from being gigged. No big deal. It sounds great so I jumped at the price after I got to test it out. And again, roll down your channel volume a bit and use your output to compensate.

With the gain at 1:00, no extra gain from your 808 and just volume for mids, it really sounds like the preamp tubes. I run my gain at 2:30 - 3:00 with my RC and don't have that kind of feedback issue on my Solo 50 or my Tremoverb. Check your cables too.
