Expertly handcrafted in typical Matchless fashion with artfully simple controls, the 45 watt Thunderman bass amp is designed to be any bass player’s workhorse.


Like all Matchless amps, the Thunderman will provide clean and usable headroom as well as plenty of raw bottom-end.  The Thunderman’s compression circuit is provided for adding a cleaner attack for tight back-up passages as well as for hard string slaps.   
The power amp is fed by a 12AX7 phase inverter which drives two EL34 power tubes which gives the amp punch and extremely sensitive touch response.  The rectifier circuit is driven by one 5U4G for warm sag.  
Other professional features include an effects loop, output impedance selector (4, 8, 16 ohms), a speaker phase-reverse switch and two courtesy AC receptacles.  
All of this is encased in an extremely sturdy hand-made 11-ply, ¾” Baltic birch cabinet, wrapped in richly textured black vinyl.  The finishing touch is our signature backlit nameplate and control panel, which lets you (and the audience) know when the power is on.
