The definition of a boutique guitar amplifier head. This a Soho HP blue line, hand built in California. It was made by Peter Stroud who played for Sheryl Crow amongst others. It is switchable between 35w and c20w. Includes the famous 'bump' circuit for adding mid and top range grunt. The sound is bright and clean, reminiscent of an AC30 or a HIwatt 103. I played it in the studio mainl through a Hiwatt 2 x 12 (also listed). It is a rare find but I believe the price is fair
