the amps made today with the hiwatt badge have little more than the name in common with real HIWATTs. Their marketing claims are very misleading.
Their so called CP103 and 504 suck compared to real HIWATTs.
I have a 1969 CP103 that really screams.
The who tabs site is more accurate than the Zep site, they have continued to correct errors in their info.
my brother has a 50W hiwatt, and its just awesome.
What albums/tours did Jimmy Page use the Hiwatts on?
