Hello, Effects Fans!
Today we announce our new Swampodillo module. It has multiple configurations that compare to the Schaller TR-68 Tremolo, the Cesar Diaz Texas Tremadillo, Monster Effects' The Swamp Thang, and the DIY pedal building community's Hearthrob by MarkM.
Sometime back in the 60's, maybe 1968, the German company Schaller started making a tremolo pedal designed to sound like the tremolos in Fender brown face amps. That was the Schaller TR-68 Tremolo. It has been out of production for many years, probably since sometime in the 80's when Schaller discontinued a number of product lines.
In the 90's, Cesar Diaz began building his own version of that circuit, which he called the Texas Tremadillo, a quirky tremolo used by some major artists.
Around 2001, Monster Effects released The Swamp Thang, which also utilizes the same circuit. Other boutique builders have released their versions of this vintage circuit, too. Builders in the DIY effects pedal community have also based designs on the circuit, including one by "MarkM" called Hearthrob.
Tremolo is a very simple effect. It is little more than changing the volume by some amount at some speed with a controlling waveform. Most of the components in this circuit are used just to alter the volume. Few of them are in the audio path and have any direct impact on the tone, since there isn't really supposed to be any impact on the tone anyway. So while there are some minor part differences used in the various versions of the circuit, the tone is very similar. The differences are in the shape of the wave that controls the volume changes.
The GT Swampodillo module comes in four configurations. Keeping in mind that the part differences are small among all of them, the Texas Thang and Swampodillo configurations are very similar, as are the German Thang and Throbodillo configurations. Some of the differences are in how the controls work and other minor things that have little impact on the tone. There are some differences due to the wave shape, though the differences are difficult to quantify and describe.
