TC Electronics G-Sharp Question

[Axis Sport]

Happy Holidays all,

Do you know why they say you cannot plug your guitar directly to this unit. The manual says to go with a pedal or pre-amp first. I tried this last night and had a strong signal, so what is the issue?

Also, this thing has a hiss no matter what the settings are. What options are there to reduce this noise.

Thanks for the help.

don't know as I don't have this unit... maybe you could try HRI or the Gear Page... those guys would know the answer to this one..

Weird... I have a G Major too and I gig with it all the time and it never crashed.

The issue is with the input impedance - it's designed for a line-level impedance, guitars require a much higher input impedance. Most pedals have a low-impedance output, as do preamps, so you'll get a better signal if you use some kind of pedal (like a clean boost). Right now you might be getting good amplitude from your guitar's output, but the signal will be loaded down by the TC, so you're definitely losing some high end, unless you're playing with active pickups.

I'd guess that it's also got something to do with it just giving time-based effects as well.

The convention says that these types of effects are best placed after a pre-amp.

If you are using the preamp for any kind of drive/distortion, then yes - this is true. That's why effects loops in amps are usually placed between the preamp and the poweramp. But definitely in TC's case they say it*must* be placed after a preamp because of it's input impedance. The specs put it at 13kOhms, which is not a high impedance input. Compare that to (just for example) an ADA MP-1 which has a 1Meg input impedance, much better suited for a guitar.
