Hi guys 'n dolls...I ve just started playing electric ( after 30 years of playing acoustic ) and is a bit on the "stupid" side here...lol
I have my guitar plugged in the V-AMP....then to the PA. The sound is fantastic, but i seem to have a prob with my sounds going away, then comming back again ( intermittently )...Im not talking about my "effects"...thats normal...I have 2x 300W IMINENCE USA speakers, and my PA pushes 2x100W...The room i play in is about 3M x 6M ( very small ), so i was thinking...Could it be because of the BASS that's to heavy for the room??...It sounds like my speakers are "sucking in" by themselfes...As soon as i "hit" the strings again ( after the sound seems to be fading away), it comes back like normal...but only for about 2 secs then fades away, and comes back "jerky" again, im just worried that its my amp...:dunno:

...if what your saying your problem is intermittent signal and you've eliminated the v-amp as your problem (works fine with headphones, batteries/ac supply are fine/don't have it cranked into the board) it could be the PA's power amp but:

Make sure you're not overloading the channel on the PA's board that the v-amp is in as it will have an overload protect and do weird stuff to your signal. When I heard your tune that you posted it sounded like you were overloading the soundcard with that v-amp too so I would look into that (turning down the v-amp)

GL :)

The PA has LED's that shows the input signal, and its hardly moving which eliminates the overloading...I might be wrong, but i realy think the place where i play is just toooo small as well...That could also be a prob, not so, eh?

From what I understand, the size and shape of the room could have a significant impact. However, though it is hard to get a clear understanding of what your problem is, the description doesn't seem to follow what would happen.

The problem with room accoustics and cancelation (what you think the problem might be) is that some certain frequencies will be less audible than others. It wouldn't cause volume across the spectrum to go down, it would just make it more difficult to hear some of the sound and so you end up sounding like shit. It might also make you appear at less of a volume than you really are, but it wouldn't make volume drop and come back.

I'm not a sound engineer, this is just my take on what I've read on the subject. You seem to be describing a real amplification problem, not an accoustic one.

mmm....not good news....I just bought this amp about 1 week ago...but ill check into it.....thx for the advice....

I think i just solved my prob...It was the f'n NOISE GATE that was set to high...lol...sh!t, now i feel better...was worried there for a while...thanks for trying to help nroberts....much appreciated :)

Yep, that would make strange things happen. Glad nothing's broken.

I was just comming on after thinking this over and was going to say check your noise gate. I never use them. You should be clean enough without it imo.
