The benchmark small tube combo

The Blues Junior has been a gigging staple for decades, and the IV refines it with a smoother reverb and a tweaked preamp. Fifteen valve watts through a 12" speaker gives you that chiming Fender clean at lower volumes, and a lovely natural overdrive when you push the master. The "FAT" switch thickens it up for solos.

It is loud enough for small-to-mid gigs, light enough to carry, and sounds wonderful with pedals in front. For most players wanting their first real valve amp, this is the one.
