Greetings TalkBass! We are Philosophy Amplifiers LLC. We are a brand new Boutique, Tube Bass Amp Manufacturer located in the San Francisco Bay Area, California. Philosophy Amplifiers Philosophy has never had trouble standing out in todays bass amp marketplace. While the market has been bombarded by countless hi-wattage, pocket size bass amplifier solutions--Philosophy has chosen to deviate from the herd. Philosophys identity stemmed with the concept of bringing the spotlight back onto the bass-player. Each amplifier delivers 200-Watts of pure, analog tube power. From a listener perspective, the amp has as much low-end and punch as a 500+ watt solid-state type amplifier. The amps harmonically rich midrange is the key to its complex and signature sound. The low end stays firm throughout the entirety of the power band, and the treble remains clear and pleasing to the ear. Most notably, the amp has a gain knob that allows the user to achieve a natural tube crunch tone if they so desire. No overdrive pedal required. Our amplifier surpasses all nearby competitors due to its unique and warm tonality, versatility, all-tube circuitry, bold and attractive aesthetics, and functionality. We stand alone in quality, as well as in our desire to build life-long relationships with our clients both local and domestic.
