In this photo taken at a gig circa 1966 Pete can be seen rocking out thru a Selmer Treble and Bass 50 with the late 60s black tolex. According to the [year-by-year gear list on Whotabs](http://www.thewho.net/whotabs/gear/guitar/history.html) Pete used these amps in [early '66](http://www.thewho.net/whotabs/gear/guitar/history.html#stage66) on the road as an alternative to the early Marshall 100 watt stacks he was also using live.more
if marhsall made a brownfaced bassman with british tubes and iron instead of making a tweed bassman that way ti woudla sounded like the selmer treble 'n bass model. A might british beast thatsplits the difference between plexi and fender with some hints of hiwatt to boot. Muscley clean and righteous EL34 grind. LOUD LOUD LOUD. Grounding is not superb, a problem common to many 60s brit amps. Nosiefloor isn't great but the whole amp likely needs to be gone over by a better tech than myself. love this guy. Its got a stout and manly sound. These can still be had for under $1kUSD if you're patient and don't care about good cosmetics.
