The M-500 has evolved from the original design in 2002. Over the years we have made numerous improvements to boost performance.

We redesigned a more efficient power output stage and lowered the operating temperature of the output devices with our custom tooling of the power amplifier heat-sink assembly. Higher efficiency and lower operating temperature yields great benefit to the longevity of the M-500. It will run for decades. A new circuit is added to allow the cooling fan to operate only when needed, so it works in the studio without ambient noise from the fan.

The M-500 is a single one channel power house with ultimate tone shaped by the 12-band graphic EQ and 3 band parametric EQ. It can power multiple speaker cabinets with ease. Our exclusive optical limiter circuit gives it a very smooth operation. Bass Player magazine in 2004 review quoted it “the best on board limiter found in a bass amp”.

2% silver solder connections; 2.5 mm steel chassis; heavy duty chrome plated corners; recessed Allen bolt mounted handle; custom machined metal and anodized aluminum knobs; and much more. No details left unattended; and they scream quality.
