Line Driver / Buffer - A Quick Question

[cat]

Hey all,

I am planning on building this {pdf} line driver. I was thinking about building it into a true bypass strip that I am making. I was planning on having a Jim Dunlop Jimi Hendrix wah in front of the true bypass strip.

My question is - I have read that buffer / line drivers dont like to have other pedals in front of them. Can anyone tell me if having the wah in front of the line driver would be a problem?

Thanks guys,

Cat

If you used a non-inverting op-amp buffer with the input impedance set high enough (like in that diagram or in GGG's IC buffer), it won't matter if anything is before the buffer or not.  Based on personal experience, however, I believe you would be better off putting the buffer in front of your wah.

I should have mentioned that I have converted my Wah to true bypass. Does this affect that at all? I am planning on using the GGG IC Buffer.

In bypass mode, probably not.  In wah mode, I'm guessing you might appreciate it.  I have an inductor-based wah/volume that uses a stereo pot.  It's not true bypass because I would want it in-circuit all the time.  I don't use a Fuzz Face so I don't worry about that.  I think I have the buffering handled because I have a compressor and a Boss Acoustic Simulator in front of it.  I also have a GGG buffer all built up with nothing to do, so I'll probably stick it into this wah.

Cool, thanks for your help David, I appreciate it
