Big Muff Pi Op Amp Fuzz with RAT filter tone stack option
This device is our take and dedicated interpretation of an op-amp based, Pi-style fuzzstortion/distortiofuzz pedal which authentically captures the late '90s Seattle-based grunge texture and tone, also featuring additional toneshaping options.
The Warlow incorporates LED clipping diodes which bring about a very pronounced low end and a truly barefaced fuzz. As pictured, it features Volume, Tone and Sustain controls, but it also has an internal switch to change the behaviour of the tone filter.
Volume controls the output volume of the pedal, to set how hard the amp is pushed or how loud the pedal is. The Tone filter lets less high frequencies pass through the pedal as it‘s turned up, similar to the Rat pedal. It can also be switched internally, as further explained in the „Internal adjustment options“ paragraph. You can adjust how much gain you want, by using the Sustain control. It ranges from smooth overdrive sounds to immense amounts of distortion/fuzz.
Switch between the Muff and the Rat style Filter. If the switch is in the position towards the jacks the Rat style filter is engaged, having it towards the footswitch selects the Muff style filter. Older models with switch inside are shipped with Rat style filter selected.
