I run a very small FX board and no more than 10' or so of chord from guitar to board, board to amp. Don't know at that point if I need a buffer, but if I do I'd rather have it housed in a tuner or FX pedal to save space. There's a couple of buffer PCB's in the catalog that I would build into my lead dirt pedal. I read about how there are buffers, then there are GOOD buffers. Do these do the job in a commendable way? In the same vain, I'm thinking of incorporating a compressor to the lead pedal in my rig that would typically be an always-on. If the output impedance of the compressor is down around 100 ohms or so wouldn't it function in the same capcity as the buffer?
