How to Make a Small On Board Buffer
Today, I would like to show you how to make a really small on-board guitar buffer.
It's based on the TL071 op-amp, which is very good for that purposes. It will allow you to make an active buffer with high impedance on the input (1M), and low impedance on the output (it's very important for buffers). The TL071 will not eat your power source too quick - will work hundreds of hours on one, typical 9V battery.

It is a very popular construction in guitar electronics. Nothing original, but will work fine for the most of our purposes. You need only six parts to make it: the op-amp, two resistors, two capacitors (one film, one electrolytic) and some small multipurpose PCB.
