The Hiwatt Bulldog 300 shares the same classic analogue preamp with the Bulldog 77. Tried and tested this Hiwatt preamp is a veteran of many recording sessions and small venues - we have replaced the old school power section with a Class -D chip and now have enough power to drive a custom 15" 300 watt speaker (and tweeter). All the low end you need for a good sized gig and DI out for front of house.
