I'm offering my Roland Dice 30 guitar amp. Specifications include a 30-watt amp, a 10" vehicle driver and integrated effects. There's some buzzing when playing quite loud or with only massive distortion - I assume it's the speaker, which would likely should be replaced - however otherwise it works well as well as is in quite good shape.
Marketing "as is" for $20, company.
