The Tourbus is a compact version of the Deluxe Memory Man™ pedal. It uses through-hole components and is relatively easy to build as a DIY project. The Tourbus PGE has the same circuit as the mbp Total Recall, with a few changes. It remains positive ground and non-true bypass, but only requires an 18v power supply instead of the EHX 24v. It includes an “overload” LED and offers the option to build it with either traditional modulation or extended modulation. The PCB design was converted to 4-layer for compactness and low noise.

To fit in the 125B enclosure, the circuit was divided into two boards: the Main board and Daughter board. The Main board contains most of the audio and LFO circuit, while the Daughter board includes the MN3005 BBD and calibration trimmers. Stacking the boards limits the size of components that can be used.

Overall, the Tourbus is a small package that retains the pure Memory Man™ sound. It is a versatile pedal that can be built as a DIY project and offers options for modulation.
