Hi Does anyone own a Yamaha BBT 500H amp head. I've just bought one. I've kept my original 2 hand made 12 inch cabs which are at 4ohms so it runs at 250 Watts. I play in a big band so it has plenty of power for my needs. The head really suits me because I like to use different sounds for DB and EB plus a third sound for slapping and popping. The 11 different sounds and 5 presets gives me plenty to choose from. The biggest challenge is to make sure the presets are all at the same volume. We don't tend to do proper soundchecks in the big band so its largely guesswork and adjusting as I go. Its slowly getting there and I've enjoyed learning to use the EQ functions and the compression functions to really shape and build each sound. I'd be interested to know how other bass players have found it.
