Loud

I got this amp in the early noughties on a closing down deal when I'd got together with some lads to jam/form a band? 100w solid state. It was loud! Better than me and managed to blow my eardrum! Ouch. Randall have ceased to exist since and I wouldn't reccomend searching for one. Best suited to heavy rock/metal in my opinion.

In the band [betwind], I use the Randall RG100G3 Plus amplifier. It's much lighter than the combos I disliked while playing with HardBreakRock. The attached photo from Bzmedia shows it in use.
