A solid-state amp with something to prove.

This amp is a real "sneaky pete". Designed by Paul Rivera, this is one of the only amps with a parametric EQ, accutronics reverb can, and true channel switching. Heavy? The transformer's HUGE. Swap in your favorite 12" speaker or plug into an external cab and this becomes your new best buddy. Turn it up, and watch heads spin. Clean or dirty, the 50-watt 1x12 is as impressive and fun as its bigger brother the G100-212 II.

Very reliable for its usual price.

Got this in a trade for a beaten up Peavey T-40 amp.

Now its my #1 gigging and home amp. Its a great platform for pedals, amd can do some very high quality cleans. Very underrated, more people should know about these things!
