The Rocktron PRO Q is nothing short of amazing. I have used it with a MESA MARK IV, dual rectifier, and also an Ampeg tube head back in the day. Think of this unit as one of the best guitar EQ systems ever made. It lets you fine tune specific frequencies that really change the sound and drive of your tone. One thing that’s awesome is this unit is fully MIDI controllable. So basically you can setup all of your presets then select them with a MIDI foot pedal. That’s how I had it setup for years and it works flawlessly. It’s great if you want a couple of rhythm and lead settings. You can also adjust the main output volume with the unit so you don’t need to touch your amp.

Famous players like Dimebag Darrel and Kirk Hammett have used it in the past.

The Rocktron PRO Q is a MIDI programmable true – stereo guitar enhancement system designed to give your existing system an added dimension of tonal variation. The unit offers a boost of up to 25dBu at carefully selected low and high band frequencies in each channel, along with a notch/boost feature in which both the notch depth/peak boost levels and frequencies are user selectable for each channel over a wide range. A mix level control is also provided for each. In addition, a phase control feature for each channel (also with mix level control) allows for even greater tonal variation while individual HUSH noise reduction circuits (with user selectable threshold controls) ensure quiet operation of not only the PRO Q but will also reduce extraneous noise from preamps and other effects router prior to the PRO Q in the signal chain.
