Great Pedal. Bought from Analogman with LED and true bypass.
This pedal does add character to your sound... it is not transparent. This however, is it's greatest virtue! As comps go it tightens your bass and treble but in a very musical way. It has a nice doinky doink (sorry my phrase) to you sound. Great Gilmour, Dire Straits, Eagles etc clean sound but also works well with overdrive etc more so if you set the output higher than 2 O'clock to full. This works well in driving any OD/Dist/Fuzz pedals.
Conclusion: From " character to clean"
Boss 4 knob thing = Not for me although the three knob is meant to be good. 5/10
MXR Super Comp = Good sustain not as clean as the 1974 Script. 7/10
MXR 1974 Script = Best character and best sustain. 9.2/10
Keeley Comp = Good clean with good sustain. 8.2/10
Mr Squishy = Cleaner than Keeley slightly less sustain. 8/10
Demeter Comp = Most transparent with good sustain. 9.6/10
I hope this helps.
