I like pre-1977 Hiwatt amps for either guitar or bass...impeccable build quality, great transformers (Partridge) with huge broadband, touch sensitive to string dynamics and guitar volume knob, pedal friendly, very durable, and best tone to my ears. I've played many, many amps over the years, but I keep sticking with the old Hiwatts: 100 watt DR103 for guitar and 400 watt DR405 for bass.
