Master Effects releases Super 800 Plus Version 2 bass pedal

December 1, 2025 · 1 sources

Master Effects released Version 2 of the Super Eight Hundred Plus in December 2025, adding a biamping feature and a 10dB pad to the bass pedal. The maker describes the pedal as "our interpretation of the 1980s Gallien Krueger 800RB bass amplifier"¹.

With the biamp switch off, both 1/4" outputs carry the same full range signal. With it on, the player selects the crossover frequency and gets independent volume controls and independent 1/4" outputs for the high and low frequencies¹. The 10dB pad, taken from the original amp, is intended to help prevent clipping with active or other high output instruments¹.

The rest of the layout follows the earlier Super Eight Hundred: a 4-band active gyrator EQ with Bass, Lo Mid, Hi Mid and Treble controls, Vol (gain), Master and Boost, plus Lo Cut, Mid Contour and Hi Boost toggle switches that shape the tone at the first gain stage before the equalizer¹. The boost runs from a footswitch rather than the toggle switch used on the Super Eight Hundred, so it can be engaged while playing¹. A full sized XLR DI jack sends a balanced signal to a board or audio interface¹.

The pedal runs on a standard boss-style 9V power supply, with internal circuitry boosting the input to ±15V for headroom in the equalizer section, as in the original amplifier¹. It is housed in a 1590BB2 enclosure with top-mounted jacks, uses soft touch relay true bypass and an FR4 PCB, and is assembled by hand in Calgary, Alberta, Canada, with a 1 year warranty on parts and labor¹.

The price is $269US plus shipping: $20US within Canada and the US, $60US to the UK, Western Europe, Australia and Japan, with other regions asked to inquire¹. Orders typically ship within 2 to 4 weeks, and customers outside Canada are responsible for customs, import or VAT charges¹. The maker states the pedal has the same tone as the Super Eight Hundred¹.
