Reamping means to record the clean guitar signal without any effects or amps. Then the recorded clean guitar can be played through any possible effects and amps combination until you get the desired sound.
The problem is that it is almost impossible to play a clean tapping guitar solo. Therefore you need to split the signal path into two parts. The first for the recording and the second is connect to the effects and the amp of the guitarist.
For this to do we don't need any special hardware. Only the external effects loop of our Boss GT-8 / GT-10.
The external effects loop must be at the beginning of the fx chain and has to be set in the correct mode.
Now you can connect the external effects loop send to your recorder.
