Guitar "samples" for testing purposes

Post by iulker »

Maybe it's a stupid question, I don't know, but for some time I was wondering if it is any computer/tablet/smartphone program, whatever, or even an device of some kind, capable of reproducing the EXACT tone, level and wave form as come out from a real electric guitar! In other words, to simulate the guitar output for testing/tuning a tube amp, without the need of another guitarist to play.
It will be very helpful for me, as a builder, 'cause I don't usually have any help from a guitarist to play my new built amps, and I'm not a guitar player myself, unfortunately ... I consider even making some demos with those samples to demonstrate the capabilities of the amplifiers.
The ideal will be to get different guitar demos, Strat, LP, Tele etc., to see how the amp respond to various type of guitars ...

You might google "reamping guitar" for a very long list of considerations and even some suggestions that are cheapish.

It's complicated, sort of.

Just get a looper. It ain't perfect, but it's very close.

Brilliant.

What are you going to tweak with the amp running?

I just need "something" able to play various type of tracks/songs/licks instead of me, if possible by selecting different type of guitars ... that's the idea ...
I'm not capable to play different type of songs - clean/blues/rock/metal/whatever, and when I build a particular type of amp, my client wanna hear the sound of that specific style through the amp.
I cannot just play 2-3 chords to show the capabilities of a Soldano SLO clone, for example ... it's useless.
Of course, I should hire a professional guitar player instead :lol:, but it's not an option for me right now.
Often, testing by the client himself is not physical possible, because of the distance ... I shipped the amps most of the time.

LE. I have read something about reamping, and the obvious down-sides, but even so I still need the dry tracks, and it seems nobody share that, or I cannot find none yet ...

I think you need direct recordings from guitar output.

Even that won't be ideal, because part of playing is based on auditory feedback.

There aren't any 'to find' you have to make them or have them made.

Agreed. There are very few unprocessed guitar tracks "out there", a few acoustic ones, but nothing much to write home about.

For testing the looper is good. Makes you want to fix the issue really quick before you go nuts.

For demonstration purposes it would be more effective to employ a guitarist who can bring those guitars and deliver the goods.
It should not take long, but you need to get the recording done right.
So equally, or perhaps even more important, is an experienced sound engineer and all the tools that he needs to capture the event too.
Sounds like a trip to a good studio, or am I over-thinking this?

Best, tony

One trip with a guy who plays a few different styles on a couple guitars. Recorded direct (meaning direct box) and then you match the levels and the input R counts. This is just a simple reamp setup but you are probably looking at 3-4 hours of time to get a bunch to work with.

Yeap, this may be working, i'll give a try. Thanks.
I'm not interested in steeling someone else's tracks, just to demonstrate the sound of the amp.
I will pay for a solution or another, if is what I need.

Just check your levels carefully. A guitar output is in the millivolt range

I'm gonna buy an Redial X-Amp to do this job properly ... I hope will help.

Reamp device won't work on its own he would still need to record the tracks and then export them, adjust volume etc.

The problem with this particular request is the volume. Not the impedance a simple 150:600 ohm transformer will knock the line level signal down to guitar signal. So you won't over load the input preamp. But you should probably still meter the MiliVoltage from the guitar cord pre your sample and match it at the cord going into the amp.

As for tone.... Ehhh it's not going to be 100% exact but it's not going to that far off depending the quality of your recording equipment and levels you track them at, sample size, etc. the kicker is some guitars can have octave flashes up in the 30khz but once this information hits an amp and is processed the speaker cabinets limit the high frequencies to about 7khz by design.

An iPod or mp3 limits your sample bandwidth with lossy compression so that is not the best avenue for samples.
Try sticking to wave files in the digital domaine or even analog tape for higher fidelity. If possible track in a computer at highest samples possible no peaking no processing and play it back inside the session so you don't have to render or bounce down to 44.1 / 16 to play in a CD (red book standard)

The looper is a good idea but only as true to tone as the quality of the converter.


Hope it helps

This is a really big problem because every guitar and player is different.

For example:
I made an amp which sounded really good with my guitar.
Then I bought "better" guitar which made my amp sound not that good.

I think the whole sound thing is about the chain:
player-fingers-guitar-cord-(pedal/s?-why?)-amp-speaker-audience

Everything is connected - I like... :)
