XO Q-Tron Plus Envelope Filter Guitar Effects Pedal Specifications:
- Drive (Up/Down)
selects direction of filter sweep : upwards or downwards.
Normal mode allows setting the Gain control without changing the output volume.
Peak (Q on the Mini Q-Tron)
Determines frequency peak of filter. Makes more "effected sound" when turned up more.
Functions as both a volume control and a filter sensitivity control in boost mode. In normal mode it acts only as a filter sensitivity control, unlike the Mutron-III which also changes the unit's output volume.
Emphasizes vowel like sounds in low position, overtones in high position.
Select the filter used by the effect: Lowpass, Bandpass, Highpass or a mix of Bandpass with dry unprocessed sound.
Selects either a slow, smooth, vowel-like attack or the fast, snappy response of the original Q-Tron.

Comments about Electro-Harmonix XO Q-Tron Plus Envelope Filter Guitar Effects Pedal:
This pedal has tons of features and has a number of good sounds available. I use it for bass and some of the modes lose a lot of low end, so I just don't use those modes. Watch out for volume spikes, though. I recommend a compressor or limiter after this in the chain, as it can get pretty wild. It also requires its own 24V power supply (included), which is kind of a pain when most pedals take 9V.
