The Peavey Windsor is an awesome harp amplifier!!! Way better than the blues junior, pro junior or deluxe. This is an incredible amp without any mods and there is no feedback problemes with it! There is also a "Power Sponge": this is like a volume speaker so you can crank up the tubes and get the tone that you want without any feedback because you reduce de volume of the speaker! This is the best amp to build your own tone!
Oh, it's a 20watts amp with solid state rectifier and preamp with 2x 12ax7 and a El34 or 6L6 preamp tube. Don't jump to conclusion with the description, this amp is fabulous!
