The Thunderfunk TFB550 Bass Amp is the direct descendent of the amp that Jaco Pastorius loved, the legendary AMP BH-420 - redesigned, improved, and handmade in the U.S.A. by Dave Funk.

With an all-aluminium chassis, the TFB550 weighs in at only 6.8kg (15 pounds).

The amp can operate with the fan switched on or off - so it's quiet for Studio or TV use and produces less hum than a tube amp.

While a tube amp might be slightly warmer, you'll soon realise that what you gain in "warmth" you give up in definition and response. With the Thunderfunk Tube Emulator switch you are able to switch between a super clean solid-state style tone for slap and double bass playing and a gutty, warm, tube-tone for all the rest.
