This is a great amp experience, it a very good clean channel amp as is and can be greatly enhanced depending on the what ever preamp plug in you may want (ToneKing) you can get crazy gain as well with Engel or Friedman models. The power section is a great tried and true 20watt supply, the same as what Friedman uses in his 20 watt heads, like the JEL 20. Serivce is provided by the manufacturer, I think the best in the business. Endless tube preamps for flavor to play with, few options out there give this tube amp fantastic flexibility. Great price and endless options for those looking to get uncompromised tube sound without breaking the bank to buy a single flavor amp every time for your next gig.

"Not a review"

I just wanted to say the gear expert opinion featured on this product is completely misinformed. EL84 tubes are definitely not part of the American tone. They're every bit as associated to British tone as EL34s. Any "gear expert" would know that for the American tone you always go with 6L6 tubes
