The Catalinbread Topanga Burnside Tremolo has all of the springy, surfy mojo of the original Topanga but now features a Trem knob that controls the rate of the lush tremolo effect. Based on an outboard Fender 6G15 spring reverb unit from the '60s, this pedal yields amazing results. Part of its magic, and how it differs from the internal spring reverb found in most Fender-style amps, is that it is run in front of the amp, causing reverb signal to distort and sound more intense.

Because there are additional knobs on the outboard units, you also have more control over the reverb qualities. The Dwell knob controls how hard the springs are getting hit by the guitar signal. The Tone knob allows the treble to be dialed back to just the right degree of brightness. The 6G15's front end is also essentially a tube preamp, so it colors the sound going into the amp. All this adds up to a very distinctive reverb sound with a lot of attitude and complex nonlinearities that are hard to replicate — available now at Replay Guitar Exchange!
