Slaving and feedback with speakers

Post by dirtycooter » Thu Nov 13, 2014 3:15 pm

So I built a load resistor for the peacemaker and while I am in the territory tonally and have complete control of volume to insane complete whisper levels. I have no feedback interaction with my cab.
Usin the DSD the regular striaght to head to cab way is almost completely uncontrollable feedback. Pete Thorn even states this and I know first hand what he means by "Banshee!"
Slavin through the matrix and I can't get it at all :? It takes the liveliness down without that interaction.
You guys usin tube slaves got this issue? I wonder whats not jivin here.
Other than that the top and bottom are where they need to be tonally and the mids are just about right on to my ear. Its a workable tone. Plenty of gain on tap and the amp head volumes are far from maxed. Bass vol noon treble vol 2-3 oclock. Its burn city here in gain land.

I once ran an MXR Dist. + into a 1950's Rickenbacher amplifier w/ 6V6's into a Groove Tubes Speaker Emulator, then out to a MicroLimiter which I output into an Alesis Quadraverb. The only stereo monitor I had for this setup at the time (early 1990's) was a small boom box w/ Aux RCA inputs which I was able to make tonally useable by clipping off the wires inside going to the little plastic "tweeters". I was still able to get harmonic feedback with no problem by positioning the guitar's strings in the path of the monitor's 4"- 6" speakers. It sounded great. Not sure why you're having trouble getting the effect. It should be speaker vibrations interacting with guitar strings to keep them going. I was sitting pretty close and aimed at the monitor though...

I am directly in front of the cab, guitar against the cloth damn near, and my matrix bridged. 1000watts. Cab pumped up loud.
Dsd, sd59, wolfgang. Doesn't feedback even a little bit.

My Rickenbacher amp was so small I had to have it cranked... What is your Peacemaker's level set at?

Its at "Jesus on a Harley" levels. Hows that for a description? :lol:
It has something to do with the slave amp I am sure somehow.

Is that DSD potted? I potted my old DSD and the banshies went away. But still, premium guitar/amp/cab interaction is best when it is just that and super loud right. :rock:

Mine is a newer dsd. I been meaning to give it a good re- soak though its supposed to be potted from the factory for this very reason. The pickup makes nice natural drive and gain but the low end is wooly I feel and I think it could be taken futther away from the strings to remedy that but its a bitch being in a pv wolfgang I already had to dig out now where it sits.
It is a PAF voice kinda deal on steroids as its frequency balance is very similar to my 59. It just has way more balls and thicker due to the high output. Same attack in both and bite.
You just blazing away unattenuated?
