BOSS DS-1 mod

Sound demonstration of a mod developed for BOSS DS-1 (the NJM2904L op-amp 2006 version) that alters the sound towards the first version of the pedal (1978 - TA7136AP pre-amplifier) that is considered to be smoother and warmer. To our ears the modded pedal sounds closer to the 1978 version (actually it was compared to a 1979) with better sustain and clarity - as opposite to current production pedals that sound a bit more aggressive and with less detail. Listen with headphones or a good sound system. You are more than welcome to share your thoughts!!
