Beyer M201 On Finger Picked Acoustic

Is it very wrong of me to feed the line in of Channel 2 of my Audio Buddy from Channel 1 to get a decent level without having to turn Channel 1 all the way up or have the mic so close it's practically touching the strings?

I can't afford a new pre amp

won't work - lots of distortion. The audio buddy (like most pres) has hi-impedance outputs. The inputs are lower impedance.
The low distortion rule is that whatever you plug into has to be the same or higher impedance.
You could solder a 1 megohm resistor in line with the center connection. That might work.

What's wrong with just turning channel 1 all the way up? Seems like that would be a lot better than pre-amping it twice (just asking for distortion). Just MHO.

Should be no problem impedance and distortion-wise. Just take the output of one channel into the 1/4" (Hi-Z) input of the other. You'll have to fiddle with the gain of each stage to make sure your not overdriving the second channel into distortion or clipping.

The problem is going to be with noise, as you're also amplifying the noise of the first channel and adding it to any noise of the second. Again, by fiddling with the gain of each channel you can get this as low as possible, and hopefully will be less than by using a single channel and cranking it all the way up.

Let us know the outcome (as I'm too lazy to try it myself.)

Actually I tried it and it worked surprisingly well. The Audio Buddy doesn't have a lot of headroom and gets pretty noisy above 4 O'Clock. The Beyer M201 doesn't have a great deal of output, and requires a lot of gain for this type of application. Put the two together and you get way too much noise. By sending a signal from Channel 1 into the 1/4" Line Input of Channel 2 I was able to get a reasonably quiet recording; without having to stick the mic right up against the strings or turn the gain up on either channel above 1 O'Clock (I used a setting of 1 O'Clock on Channel 1 and 10 O'Clock on 2).

If I had the means I'd post a sample.

BTW: No distortion
