Record electric guitar with HI-Z

Postby aviorrok » Wed Sep 23, 2020 9:40 pm

Hi,
I’m trying to record my guitars with my audio interface (UR242) I turn on the Hi-Z the gain now louder but not enough. I also tried to record with my preamp (WA273) and the gain is low (lower than the UR242) why? The problem maybe on the TS cable?
(With 70% gain knob and pick the db pick is 13-12dbfs)
Thanks!

12dbfs or 70% gain? I want to reach 12 with 30-40% gain knob

Why? Almost does not matter how you get it there but you want your initial guitar recording at around -20dBfs (24 bit, 44.1kHz recording). If, with the guitar controls flat out the AI is giving you about that level then good on the designers. Quite a few AIs put too much gain in instrument inputs, I suppose the 'Marketing Men' insisted that 0dB fs is always possible with even the wimpiest plywood Strat. The result is, a hot humbucker will overload the front end of the interface and that does not sound nice. There was at least one famous AI maker that fell foul of this problem a few years ago.

Even recordings at -30dBfs can be digitally boosted and the only noise with be that of the guitar which, by the way will be only some 60dB below the wanted signal.....IF you are lucky!

But, if you really want to hit the DAW harder there are clean boost pedals about.

Both. You’re able to reach a decent level (perhaps a bit too hot, even) with the given gain range of the interface, so there is no problem.

Also bear in mind that a lot of preamps in interfaces suffer from ‘gain bunching’, where most of the available gain is bunched up in the gain knob’s last few degrees of travel. Taking that into account, there’s a chance that you’re at quite a bit less than 70% of the available gain, even if the knob position suggests it.

Then use a high output pickup.. :)

"Taking that into account, there’s a chance that you’re at quite a bit less than 70% of the available gain, even if the knob position suggests it."

Very good point Ramirez, the gain or volume control of a device, be it interface or guitar amplifier never gives a genuine relationship between angular position and electronic effect. Only very expensive, high end gear will have properly 'calibrated' controls and faders.

This is encapsulated in the famous line from the film Spinal Tap "This one goes up to eleven!"
Only a very tiny proportion of us audio geeks ever really 'got' that!

Loud enough for what?

I also tried to record with my preamp (WA273) and the gain is low (lower than the UR242) why?

It has a different gain structure

The problem maybe on the TS cable?

What problem? But a TS cable is very easy to test with a cable tester or another source.

With 70% gain knob and pick the db pick is 13-12dbfs

That sounds perfectly ideal to me as a tracking peak level.
