Simble Predrive is not just a preamp, it is a preamp/booster/compressor/upper harmonic enhancer.
Simble Predrive boosts the signal and compress it without slow attack time and also adds musical harmonic overtones too.
This musical tonal combination is totally adjustable with your picking attack and guitar volume pot.
Easy to use, you do not even want to use the switch (to turn it off).
