Here is what Mike says...
'Tin of Rock: Rock Loud with the Tin of Rock Cranked amp overdrive at your feet.
The Tin of Rock allows you to get that pushed amp sound at reasonable volumes from your amp. The controls are simple.. Rock and Loud.
Rock is your Gain control and Loud is your Volume. The Tin of Rock runs on 9v external pedal power or internal 9v battery.
For those that care.. This is a transistor based overdrive utilising asymmetrical diode clipping to get a more tube amp feel. Get great tones and keep the neighbours happy.
Get the Tin of Rock. '
