Topic: Effects loop output impedance issue. What buffer works best

I have searched all over and havent had much luck. I want to recover the tone from my Carvin  legacy2 whilst running the G 4 cable. My understanding is that the effects loop on the L2 is a 10k ohm send. I have put a Boss GE7 EQ before the G in the loop side and it seems to help but it isn't as good as the guitar straight into the amp with nothing in the loop. I fear all I am doing is mask the problem

All of the info I have found has talked about buffers that are first in line right out of the guitar. I am wondering what works best in the effects loop
Valvulator, Radial dragster, Wampler, Klienulator are the units I have read about.

Anybody have an idea on this

Thanks

If you are putting the buffer between the amp send and the G insert return, I would avoid the Valvulator. The Valvulator sounds great with a guitar plugged into it in front of the G (I use one), but folks who have tried it as a loop buffer have been dissapointed.

If you can find a good passive DI that does not pad the signal, you should try that first. It will be about the same price as the least-expensive of the buffers, and has the advantage of having BALANCED output to help further with signal-quality. If you do this, you'll need an XLR(F)-TRS cable to run between the DI and the G.

Thanks Laird. I did the cable send to return test and it is not that bad. I am running my Boss GE7 right out of the effects loop send & before a Boss NS2 and it sounds great.

Do you see any problems with that type of setup as opposed to using a DI or Buffer of some sort

Thanks again

If it sounds good, then its not worth doing anything about it. Its not like it is going to change as you go from place to place or anything.
