Coolsound-Lab is a little laboratory of handmade pedals, preamps, amplifiers and other musical gear run by Sandro.
Timeline (by Sandro)
- May 2004: my first audio pre-amplifier for hi-fi :-)

- 2007: selling first pedals and working for a luthier.
- 2008: working seriously at "TubeOnHand" project renamed in "Coolsound" making good quality musical gears, some positive feedback received
- 2009-2011: more visibility in audio context, musician's sessions, forums and websites, better quality and definitely wherever possible "all tube circuit technology philosophy"
