Boss TR-2 Tremolo|Boss TR-2 Tremolo is now part of! All the Boss pedals you love are still here, along with expert reviews of electric guitars, amps, and more.

The PN-2’s replacement has a little fewer features than its predecessor. Gone is the stereo in and outputs and gone is the panning functionality. Instead the TR-2 is a pure tremolo pedal. It has a Low Frequency Oscillator (LFO) that can be gradually adjusted between square and triangular wave forms and this makes for a wide spectrum of tremolo sounds.
