This is basically Tech 21's Sansamp pedals built into an amplifier ...with a 10" speaker by Eminence. Great tone!! It's 100% analog...so no tubes to deal with...and no solid state components. 30 watts. Effects loop. Extension speaker output. Headphone jack. Real spring reverb. Black tolex with a tan cane grill cloth. Leather handle. Weighs in at 14 lbs. Factory cover. Built in NYC...USA. A fantastic practice amp with many options. Was $400. new. This one is in virtually new condition....purchased earlier this year.
