Slaving is quite damn awesome.

@ Blix.

Can you try to slave the 1960 to your 5150 III 50 watt amp using the FX return input of the EVH amp?
I am verry curious how that will sound.

I just tried it, and it sounds really good standing in front of the cab. Very open and punchy.
Interestingly it didn't record half as good, more brittle and kinda hollow mids. I didn't bother to make a clip.
Sounds quite a bit better recorded with the Matrix power amp.

I was using my 5153 as a power amp a few years ago. Sounded 'different', but could never get close to Ed's sound using it. It sounded ok though, but you need the poweramp as clean as you can get, as people have been saying. It's too coloured.

I'm using an old Peavey Classic 60/60 and it works great. Craigslist for $200.

Those old 60/60 Peaveys are great. I used one back in the 1990's w/ a stereo 4x12 cab & a Boogie Studio Preamp, one side dry/one side wet effects from an Alesis Quadraverb... Not exactly slaving the way I did it, but it sounded GREAT!

+1 on Slaving and the Classic 60/60. Check my clip.

This is awesome. Is there a guide on how to do this?

Can I use the David Bray line out?

I understand slaving, what I don't get is where in the chain that big ass resistor goes. I would assume,

speaker output from plexi.......stick of dynamite resister........line out box.........time based effects.....power amp......speaker cab

So, you need a speaker cable on one end a 1/4 jack and then bare wire which you soldier to each end of the resister (in and out?)

confused

I have a Marshall power brake. CAn that be modded to have a line out? Does anybody know a place that will do that?



Thanks

Plexi speaker out has 2 wires, one goes to one end of resistor, the other goes opposite. Then you either connect your line out to those connections, or you connect a parallel resistor then a series as a voltage divider to another 1/4" jack for your line level. The "stick of dynamite" takes the place of a speaker. The line out or voltage divider takes it down to a smaller signal. I also added a isolating transformer in between to eliminate ground loop problems like high pitch sqealing from the effects.

Those 60/60's get high praise from me !. Even the 50/50's for the 2 spacer and in the 1 rack space department I do the ADA MicroTube 200.

Yes you can use the Bray, that's what it's made for...

Amp speaker out-into line out box-into resistor.
The resistor just replace the speaker cab. You wire the speaker cable to the resistor as it were a speaker.


Just get the Bray box, no reason to mod the PB, and will cost less.

There is another drawing for a line out box on the Grateful Dead Forum (http://www.rukind.com/forum/viewtopic.php?f=419&t=11321" onclick="window.open(this.href);return false;) for those who would like to build their own. It does not attenuate. It only taps a signal from the speaker cable. I built one to use with my 50 watt plexi quite some time ago. It cost me less than $10 in parts and it works great. On my line-out box, instead of the 30K resistor marked as R2, I used a 100K Pot in series with a 33K resistor so I could dial the tone of the signal to my liking. See attached pics and a direct link to the drawing below.

you must try to keep the impedance into a decent range : 1-10 k will be pretty fine to acomodate any fx devices. the frequency compensation is debatable as you have not the same signal shape into the output line as in speaker , and anyhow can control that direct from fx tone control. better to use a good speaker simulator in front of fx chain. a good one can take the voltage direct from speaker output aso.
I use other the speaker output direct into a palmer adig through tc electronics m-one and a peavey solid state mono monitor amplifier. if you cab can be use in stereo configuration you can use two speaker for dry signal and two for wet.otherwise two separate cabs will be better
it is awesome indeed. better to mix acoustic signals instead to mix electric ones into a fx loop, no matter which.

Using a quality line-out-box like the CAE I use, or the very similar Suhr , there's absolutely no reason to use speaker simulation, it will ruin the tone.

Is anyone using a reactive dummy load like the one Aiken describes? The difference for slaving is significant.

There is a great thread about it here:

The difference for slaving is significant.

I'm not sure it's that significant after all, some reactive load makers claims resistive loads are useless, but my clips using one tells another story IMO... And EVH seemed to do fine with one the couple tours he used them

Listen to the clips in that TGP thread. The clip with the resistive load sounds flat but the reactive load sounds nearly identical to the non slaved clip. Maybe not significant until you A/B them.
