would this harm my amp?

[nero1985]

im gonna build one of those FX LOOP volume boxes but i was wondering if it would harm my amp if i put the master volume all the way to 10 and the FX LOOP volume to control the overal output,

thanks!

To my knowledge, not at all.

On ANY amp, you should be able to turn all the knobs to 10 and not harm the amp. (Unless there's a warning, which is highly unlikely). It's the manufacturer's job to make the amp foolproof.

Not likely if you do it right.

You should get the schematic of your amp, just so you know how you'd be modifying the circuit.

He won't be modding the amp, he'll be putting a pot in the FX loop.

I understand that. The advice is still valid.

Nero, your amp is a Valvestate right?  That means it has a pre-amp tube in the pre-amp but uses a solid state power amp.  The volume box probably won't help much because all the "good" saturation of solid state amps is in the pre-amp.  It's not like tube amps where there's good overdrive in the power amp when pushing those power tubes.  If you saturate a solid state power amp, it will most likely sound like s**t . 

Using the volume box in your effects loop won't hurt your amp any, but it won't help either even if you set your master volume to 10.  Heck, even in tube amps it's not letting your push the power tubes more.  It's just limiting the signal going through the loop so you can adjust that touchy master volume without it cutting off at 1 and blowing the neighbors in to the next zip code on 1 1/2.    Fender master volumes are touchy like this.
