Other companies need a lot of buttons for a good sound, we only need 3 for each overdrive pedal and 2 for the clean boost pedal. From slightly distorted bass with tube sound character to completely distorted - no problem for the LDP (OD/CB). The overdrive pedal has a deep boost (toggle switche) to push the lower frequencies without getting muddy. The clean boost with deep boost (toggle switch) gives a lot of pressure to the sound and up to +20 dB (toggle switch) output level. From sweet to neutral to funky, the clean boost active tone control does it all. Two completely different sounds.
