The Maxon 9-Series is a line of effects pedals from Maxon that includes the PT-9 Pro+ alongside the CP-9 Pro+ compressor. Both pedals are entirely new designs with true bypass switching and 18-volt circuits, aimed at players who want the 9-Series format on their pedalboard. Both pedals eat batteries, so use of an adaptor is recommended1.
What It Does
The PT-9 Pro+ is the overdrive pedal of the 9-Series. According to a Guitar Player Magazine review of the series, the CP-9 Pro+ and PT-9 Pro+ "are entirely new designs with true bypass switching and 18-volt circuits (for added headroom and reduced noise)"1. For a player, that means the pedal passes your clean signal untouched when switched off, and the higher internal voltage gives the overdrive more room before the signal runs out of headroom, with less noise in the circuit.
One practical point from the same review: "Both pedals eat batteries, so use of an adaptor is recommended"1. If you run the PT-9 Pro+ on a battery, expect to replace it often, so plan on powering it from a supply.
The 18-volt circuits in these pedals drain batteries quickly. Guitar Player's reviewer recommended using an adaptor rather than running on battery power1.
