ratiug Posted March 11, 2004 Report Share Posted March 11, 2004 hey all, my first post: I've got a late 70's early 80's fender twin 100 watts. I also reciently aquired a preamp called a peavey tg raxx. It's a tube pre amp. I like it because it allows me to overdrive the twin a little bit more. Without it the twin has to be at an insane volumn to just barely start to break up. Anyway I run the guitar through a bunch of boss pedals then to the preamp then the amp input. Now I was told by someone that that is not a good thing to do b/c the signal going into the twin is to much! He said typically a preamp is placed in the effects loop of which I don't have. Please tell me if I should stop doing this or if it's ok. Thanks Quote Link to comment Share on other sites More sharing options...
ansil Posted March 12, 2004 Report Share Posted March 12, 2004 most inputs on amps are made to withstand 1v peak to peak. so it is a wise idea to pad down the output volume a bit but it should be fine. i have done similar things with wonderful results and no problematic issues.

JohnnyG Posted March 12, 2004 Report Share Posted March 12, 2004 man personally id just stick the preamp there and just learn how to fix any problems with the amp myself lol Quote Link to comment Share on other sites More sharing options...
lovekraft Posted March 12, 2004 Report Share Posted March 12, 2004 If you pump too much signal into a Twin, you should be getting insane blocking distortion - if you're not, rock on and don't worry about it. Unless you're getting what sounds like a gated fuzz sound, you're just overdriving the first preamp stage, just like a Mezza/Boggie (yeah, remember, Randall got his start adding a gain stage to Fender amps).

ansil Posted March 12, 2004 Report Share Posted March 12, 2004 also if you have a multileter you could measure the otuput voltage off of the preamp.. by inputing a sine wave.. say at 1khz and measure it with the settings that you are playing with currently..

ratiug Posted March 16, 2004 Author Report Share Posted March 16, 2004 Thanks all I appreciate the response.One of the music stores I do work for has all sorts of electronic measuring gadgets that I may look into for measuring the out put. In the mean time I think I will go on using it. Quote Link to comment Share on other sites More sharing options...
