Slaving is quite damn awesome.

Edcor manufactures transformers for $7 that may be suitable for line out boxes. The PC10k-10k has a frequency response of 20Hz to 20KHz. I bought a couple for testing. There is no magnetic shield. However, since this audio transformer is for reamping it should test well, if not great, for guitar frequencies. I won't be plugging into a mic preamp. If I was I probably would have purchased either a Jenson or a Hammond.

See attached drawing. It depicts a box with both phase and ground switches.

Does it work?

It works great live for my wet/dry rig. Silent recording is a different story. I didn't have the same success as Blix. I still need to use a speaker cabinet impulse (Red Wire) in my DAW to refine the sound to get my tone. I used a 39K resistor instead of 21K. I tried a few different values and I ended up on the 39k.

I would not go for a cheap transformer for these applications... a couple of points:
If we are talking about a 1:1 tx
1) Freq response: Just because the transformer can pass a particular frequency does not mean that its amplitude or quality is acceptable. You want the amplitude to be the same for the input as the output at any given frequency.
2) Quality: Even if the tranny has an "even" frequency response from input to output, it might add undesirable artifacts (or deficiencies) to the waveform. Audiophiles check for this by running a square wave thru at various frequencies, then look for the corners of the wave to maintain their sharpness.

I uploaded a brief sample that was recorded using the line out box with the edcor audio tranny. You can judge for yourselves the quality of the 10k:10K transformer. Amp was dimed and was made silent with two 16ohm resistors in parallel at 150W each. In the DAW the sample was eq'd and speaker impulses were added to simulate a cab. I can't get anywhere near the quality of Blix's recordings without using impulses. I need to simulate the moving air of the speakers.

The pickup isn't anything special. A simple alnico 5 humbucker. In the attachment, my sample riff is first and the Women In Love iso is second.

IMO I think this line out box is a good cheap option for guitarists who can only record their tube amps quietly. Some creative eq'ing will help to get a usable tone.

Peace.

For the record, my clip is a miced cab, not direct.

whoa johnnybgood - that sounds nice - i like the snap of the G string on that - open and reactive to the touch - very cool - would love to hear it w/o VH track.

[johnnybgoood]

would love to hear it w/o VH track.

Here's the riff without Eddie's track. One with drums and one without. Thanks!

dude. that sounds JUST LIKE IT! excellent job man. wow. i need to back through this thread to see if you listed everything you are using because this is a definite recipe for the DUTCH TREAT.

reference the man himself:

WOW - i just read the thread - this is DIRECT?!! I think it sounds really really good.

What's a DAW? I'm an idiot.

[johnnybgoood]

What's a DAW?

Here is the routing for direct recording.

guitar --> amp --> line out box --> USB digital audio interface --> computer --> Digital Audio Workstation software (DAW)

Important: Amp must also be connected to a load with a matching impedance to the amp (ex. Wire wound resistor(s) with heat sink @ 8 ohms & 300 watts)

Examples of DAW software are Cakewalk, Pro Tools, Reaper, Cubase, and Ableton Live. They're all great.

Sound engineers use mostly computers now for recording. It's just more convenient than tape. Hope this info helps.

[rgalpin]

oh! DAW. duh!

when you say "speaker impulses in DAW" what are you referring to? A plugin? Or are you actually feeding something into the input in addition to the line out DI signal?

I have been lurking around this site for a few years but have never posted until now. The slaving and re-amping threads are intriguing to say the least. While I do not necessarily strive to reproduce Eddie's tone, the concepts within this thread apply to many issues those of us with large rigs deal with - which is playing at a resonable volume while still getting the tone of a cranked amp. This thread has some very encouraging sound clips, one from a miced cab, and one from a line out source. What would be great is to have a sample of the first clip (Blix) recorded from the line out and a clip from the second source (johnnybgoood) from the miced cab of the slaved setup. Comparing how the miced cab sounds with respect to the line out in both situations would be most helpful. It appears that both are using a resistive load, but since each player is using a different slaving amp, are different players, and are using different recording methods, comparing the two is like comparing apples and oranges.

Anyway, thanks for all of the great info already!

[rgalpin]

got it thanks!

This past Friday, I got to do a live show with my 12 Series and a Peavy 60/60 PA (thanks to YMI5150?) and man what a difference. When compared to doing straight attn with a HotPlate, there's a night and day difference. Less nasally artifacts and the rig just responded harmonically and the compression was insane. The other HUGE benefit was that I was able to run an EQ pedal in the line out with a slight level adjustment and finally had a true boosting system for leads. Yes it's more of a hassle, but probably will only use this setup for larger gigs and home.

Did you use the Hotplate as your load?
